These multi-purpose units are ideal for incubation and activation of cultures, enzyme
reactions, immunoassays, melting/boiling points and a wide variety of other laboratory
procedures.
1. Switch the three (3) position rocker power switch from the center off position to
the low range or high range position as desired. The controls are divided into two
separate heating ranges, both thermostats having graduations to assist in setting
the desired temperatures. The left hand ‘low temperature adjust’ controls from
slightly above ambient to approximately 100°C. The right hand ‘high temperature
adjust’ controls from approximately 75°C to 150°C.
2. The rocker switch has a center off position and is used to select the desired operating
range. When operating at the point where the two thermostats overlap in temperature
range, the proper thermostat must be chosen for the task being performed. Move
the power switch to the desired operating range and turn the matching range
temperature control knob clockwise to increase the temperature within the range
selected. The heat indicator light will illuminate during the operation of the heater.
3. The temperature may be verified by placing a calibrated thermometer in the test
solution or by insertion in the modular block thermometer well provided. This hole
fits regular glass bulb thermometers or small diameter digital probes. Due to air
currents and radiation losses, the temperature in the test solution will be lower than
the temperature in the block itself. For the most accurate readings a thermometer
should be placed in a sample test tube with solution matching the samples being
tested. If the temperature is too high or too low, adjust clockwise to increase
temperature, counter-clockwise to decrease temperature. Slight adjustments will
usually suffice to correct the temperature setting. When the heat indicator light
flashes on and off intermittently, check the temperature again. Allow sufficient
time for the temperature to stabilize before re-adjusting. This procedure should be
followed until the desired temperature is reached.

Designed for applications that require repeatable results and superior temperature
stability. These multi-purpose units are ideal for incubation and activation of cultures,
enzyme reactions, immunoassays, melting/boiling points, and a wide variety of other
laboratory procedures.
For best performance, the Dry Block Heater should be used in a stable environment.
The unit’s environment should have no air currents, drafts or temperature changes
and it cannot be placed in direct sunlight. The unit requires a stable electrical supply
that is free of voltage fluctuations. An unstable environment will adversely affect the
performance of the unit. For example, even minor air drafts or temperature changes
will adversely affect the unit’s ability to maintain a stable temperature.
1. Getting ready:
a. When using the external RTD probe, plug the RTD probe into the three (3) pin
DIN connector at the back of the unit and place the thermometer portion in the
thermometer well of the modular block. When using multiple blocks, place the
RTD probe in the front right modular block.
b. Press the standby button to change the unit from standby mode. The
temperature display, time display and probe indicator light will illuminate. When
not using the RTD probe, the plate indicator light will illuminate. The temperature
display will alternate between the actual and set-point temperatures.
2. Setting temperature:
a. Press the up/down arrows to the right of the temperature display until you reach
the desired temperature. Holding down either the up or down arrow will cause
the set temperature to change rapidly, a single pressing of either key will move
the set temperature by 0.1°C. When you release the button, the display will
blink off and then on, indicating the new set temperature has been accepted.
Once the set-point has been programmed and the keys are not being pressed,
press the on/off button to the right of the temperature display to activate the
heating function. A green indicator light will illuminate next to the on/off button
indicating the heating function is on. The actual and set-point indicator lights
will alternate between set and actual temperatures. There are three (3) audible
beeps to indicate the set-point temperature has been reached.
b. Set-point temperature adjustments can be made without interrupting heating
using the up/down arrows to the right of the temperature display. After the
change has been made and you release the button, the display will blink off and
then on indicating the new set temperature has been accepted.
c. To stop heating, press the on/off button to the right of the temperature display.
d. Allow time for the temperature to stabilize. The actual temperature displayed is
the temperature at the bottom of the modular block or of the RTD probe. Once
the displayed actual temperature agrees with the set temperature, several
minutes should be allowed for the temperature to stabilize throughout the block
evenly.
Overshoot protection: If the unit exceeds the set temperature by 10°C, the unit will
automatically stop heating.
3. Setting timed mode: Programmed time.
a. Press the up/down arrows to the right of the time display until you reach the
desired time.
b. Start this function by pressing the on/off button to the right of the time display,
the unit will run for the selected time. When using the timer in conjunction
with the heating function, when the time display reaches zero (0:00), four (4)
audible beeps will indicate the time down function is complete. Both the time
and heating functions will shut off automatically and the time display will default
back to the set time. To repeat for the same time, simply depress the on/off
button again.
c. To interrupt an automatic timing cycle before it is completed, press the on/
off button to the right of the time display. The time display will flash until you
resume the time function by pressing the on/off button again. This interrupt will
not stop the heating function, the heating function will stop only when the timer
reaches zero (0:00).

4. Setting time to zero (0:00) and continuous mode: Accumulated time.
a. Press and hold the on/off button to the right of the time display. After three (3)
seconds, the display will indicate the previous set time.
b. Simultaneously press both the up and the down arrows, the display will indicate
zero (0:00). The unit time is now set to zero (0:00) minutes. Alternately, you can
use the up/down arrows to get to zero (0:00).
c. Press the on/off button to the right of the time display, the display will indicate
actual running time. The up/down arrows will become inactive. To stop timer,
press the on/off button again. IMPORTANT: This will not affect the heating
function. Press the on/off button to the right of the heat display to interrupt the
heating function.
d. To reset, press and hold the on/off button to the right of the time display. After

(0:00).
5. Turning unit off:
a. To turn the unit off, press the standby button, the temperature and time displays
will be blank, the standby indicator light will turn on.
CALIBRATION PROCEDURE
This procedure is used to fine tune and calibrate the block temperature at a specific
temperature setting. It will only be active without an external temperature probe
connected. This process may be repeated for up to three (3) separate set-points. If
a fourth calibration set-point is entered, the first set-point entered will be overwritten.
1. Turn unit on.
2. Set desired temperature.
3. Stabilize twenty (20) minutes or more, measuring the block temperature with a
calibrated precision instrument or thermometer.
4. Press and hold standby button, then press the temperature up button once. The
unit will beep two (2) times, confirming calibration mode. The display will now be
flashing.
5. Press the temperature up/down arrows until the display matches the temperature
probe/thermometer.
6. Press standby button to exit calibration mode and return to normal heating.
This process may be repeated at the same set-point multiple times for fine tuning if
desired.
The unit will now use the biased offset for that specific temperature setting and
increase or decrease temperature accordingly to bring the block temperature to set
temperature. The decimal point of the display will flash to indicate a biased offset is
being used. All other temperature settings will use the standard internal calibration. This
offset will be stored in memory and retained until reset.
To restore unit to factory setting:
Press and hold standby button while pressing the temperature down button once. The
reset will be confirmed with two (2) beeps. Press the standby button to exit calibration
mode and return to normal heating.
BEEPER PREFERENCE
To silence beeper operation (except for error codes), with the unit in standby mode,
press and hold the time on/off button and press the standby button. To restore
normal beeper operation, remove AC power to unit for 10 seconds and then restore.
Alternately, you may have to turn the unit on and press and hold the standby button
and press and hold the time on/off button simultaneously.

MODULAR HEATING BLOCKS AND SAMPLES
Only Ohaus Modular Heating Blocks are to be used in the Dry Block Heaters.
1. Select the proper blocks that will be a precise fit for the tubes, plates, or vials that
you will be using for your application.
2. Only plastic or glass tubes, plates, or vials are to be used in the Modular Heating
Blocks. Metal vessels will adversely affect the temperature performance of the unit.
Metal vessels will dissipate too much heat into the air, thus adversely affecting the
temperature readings of the unit.
3. Blocks need to be in all positions on the unit so the heating plate is not exposed to
the environment.
4. To ensure proper heating, the tubes, plates, or vials that are used must be the
correct size for the Modular Heating Block. The tubes, plates or vials must fit
securely in the hole with no air gaps and maintain as much contact as possible with the
wall of the block. This will ensure good thermal contact between the Modular Heating
Block and the tube, plate or vial you are using for your application.
5. For proper heating, the fluid level within your tube, plate or vial should not exceed
the height of the Modular Heating Block. If your application requires the fluid level
to be above the height of the block, then a temperature cover is recommended.
6. When using a temperature measuring device in a sample, the end of the probe
should be placed at the bottom of the sample and the height of the liquid should
not exceed the height of the Modular Heating Block. Ensure that your temperature
measuring device is designed for immersion in liquids.
7. Contact your Ohaus representative for information on ordering Modular Heating
Blocks and other Dry Block Heater accessories.

TEMPERATURE TESTING
1. To ensure good thermal conductivity, select the proper Modular Heating Block
for your application. Select the proper tubes or vials which are the proper size for
the Modular Heating Block. Close contact, with no air gaps, must be maintained
between the walls of the Modular Heating Block well and the sides of the tubes or
vials.
2. Fill the tubes or vials so that the fluid level does not rise above the top surface of
the Modular Heating Block.
3. Select a temperature measuring device that is designed for immersion in liquids.
Place your calibrated temperature measuring device in one of the samples so it
reaches the bottom of the tube or vial. Once the temperature measuring device is
placed in the fluid sample, ensure the fluid level is still below the top surface of the
Modular Heating Block.
4. Set the desired temperature on the unit, allow the unit to reach this temperature,
and let the unit stabilize for an additional twenty (20) minutes or more before taking
any temperature readings.
5. The temperature can also be tested by utilizing the thermometer hole in the Modular
Heating Block. A calibrated temperature measuring device can be inserted into the
thermometer hole where there is a snug fit and close contact between the walls
of the block and the temperature device. The temperature device must reach the
bottom of this hole with no air gaps. Follow the procedure above for allowing the
unit to reach temperature and stabilize before taking any temperature readings.
6. If the measured temperature on your temperature measuring device does not
match the actual temperature on the display of the unit (for Digital units only), then
the single point calibration procedure can be used. By doing this, the unit will now
be more accurate at that set-point for your specific application.
STABILITY TESTING
1. The manufacturer has performed temperature stability tests on Dry Block Heaters.
The manufacturer used calibrated temperature measuring device for the stability
tests. Units were set-up with the proper number of Modular Heating Blocks so
the heater plates were not exposed to the environment. A calibrated temperature
measuring device was inserted into the thermometer well of one block on each
unit. The testing temperature was set, the units were allowed to heat up and
stabilize for a minimum of twenty (20) minutes and then temperature readings
were recorded at regular intervals for four (4) hours. These tests confirmed the
temperature stability of the units.
2. The recommended procedure for testing the unit’s stability is as follows:
a. Set-up the unit in a stable environment.
b. Set-up the unit with the proper number of Modular Heating Blocks for the unit.
Place a calibrated temperature measuring device into the thermometer well of
the Modular Heating Block. The temperature device should have a snug fit with
no air gaps in the thermometer well. Set the temperature of the unit. Allow the
unit to reach temperature and stabilize for twenty (20) minutes or more and then
take temperature readings for stability.
c. Another method to test for stability is to set up the unit with the proper number of
Modular Heating Blocks and then place the proper fitting tubes or vials into the
blocks. Fill the tubes or vials with liquid, where the liquid level is lower than
the top surface of the Modular Heating Block. Use a calibrated temperature
measuring device that is designed for immersion in liquids, and place the
temperature probe in the bottom of one of the tubes or vials in one block. Set
the temperature of the unit. Allow the unit to reach temperature and stabilize for
twenty (20) minutes or more and then take temperature readings for stability.
Please note the characteristics of the liquid used for the test and the fit of the
tube or vial in the Modular Heating Block can affect the results of a stability
test for the Dry Block Heaters. Tubes and vials must be the proper size for the
Modular Heating Block so there is a secure fit with no air gaps to ensure good
thermal contact.

UNIFORMITY TESTING
1. The manufacturer has performed uniformity tests on Dry Block Heaters to
ensure even heating across the entire heater plate. For the one block heaters,
the manufacturer used a specially designed Modular Heating Block with five (5)
temperature holes. Five independent calibrated temperature measuring devices
were used during the test. For multiple block units, Modular Heating Blocks were
placed in all positions to cover the entire heating plate and then an independent
calibrated temperature measuring device was used in the thermometer well of
each block. For all tests, the tip of the temperature measuring device was an exact
fit for the temperature well in the Modular Heating Block with no air gaps. The
temperature was set and the units were allowed to heat up and stabilize for twenty
(20) minutes or more. Readings were then taken at regular intervals to monitor the
temperature uniformity for four (4) hours. These tests were repeated after rotating
the temperature measuring devices to different thermometer well positions to confirm
the temperature uniformity of the units.
2. The recommended procedure for testing the unit’s temperature uniformity is as
follows:
a. Set-up the unit in a stable environment.
b. Set-up the unit with the proper number of Modular Heating Blocks to cover the
entire heating plate. Then set up the blocks with the proper fitting tubes or vials.
Place liquid samples in tubes or vials where the liquid level is lower than the
height of the top surface of the Modular Heating Block.
c. Select multiple calibrated temperature measuring devices that are designed
for immersion in liquids. Use these temperature measuring devices at the
same time across various positions in the Modular Heating Block(s). Place the
temperature probes in the bottom of several of the filled tubes or vials. Ensure
the liquid levels in the tubes or vials with the temperature probes does not rise
above the height of the top surface of the Modular Heating Block.
d. Set the temperature of the unit. Allow the unit to reach temperature and stabilize
for twenty (20) minutes or more and then take temperature readings from all the
temperature devices to test for temperature uniformity
