1. Take the narrow end of the connector (4) in one hand and the main body (2) in the other and

unscrew the two. Pull away the cable clamp (3) and unscrew the end plug (1) to reveal the four

parts that make up the connector.

2. Loosen the screws on the cable clamp (3) to allow enough room to pass the power cable through.

3. Pass the power cable through the end plug (1), the main body (2), and the cable clamp (3), and

then connect the three wires (live, neutral and earth) to the connector (4) as follows:

1. Live (brown)

2. Neutral (blue)

Calibration

Calibrations can only be performed once the instrument has been installed and configured.

Note: The temperature sensor is factory calibrated and can only be changed by a Hach representative.

K-M1100 sensor calibration

Sensor calibration

The sensor can be calibrated manually on an ad hoc basis. By default, the mode is set to zero

calibration with auto-end.

For higher level concentrations (above 1% oxygen which corresponds to about 400 ppb dissolved

O

2

) a high level adjustment can be performed using a gas mixture containing more than 1% oxygen,

or a known line sample. However, this should not be done without first ensuring the zero point is

accurate. This can be achieved by performing a zero calibration first.

Low range sensors: (K-M1100-L spots)

There are two calibration modes available - zero or high level adjustment. The sensor is factory

calibrated at zero. During use, the zero calibration is the best calibration to guarantee the sensor

specifications. After a spot replacement, a zero calibration is recommended.

High range sensors: (K-M1100-H spots)

There are three calibration modes available - zero, high level adjustment or in 100% humid air. The

sensor is factory calibrated at zero and in 100% humid air. During use, humid air calibration is the

best calibration to guarantee the sensor specifications. After a spot replacement, a zero calibration

and a 100% humid air calibration are recommended.

Initial sensor calibration

The sensor has been calibrated at the factory prior to shipment and is ready for use upon delivery.

However, if the sensor has not been used for a period of more than six months since delivery or if the

sensor spot has been replaced or changed in any way, then a sensor calibration will be required.

1. From the Main menu, select Calibration followed by Gas sensor and then Configuration. Make

sure the parameters are set as follows:

Option Description

Auto-calibration Not available for this sensor.

Manual-calibration Make sure that the Auto-End box is checked.

Hold during calibration or

verification

Make sure this box is checked.

Zero calibration bottle Make sure this is disabled by unchecking the box as it is not relevant

for this sensor.

2. Exit from the configuration screen by pressing OK.

3. Select Calibration and perform a manual zero calibration as described in Zero calibration

on page 19. For high range sensors perform an additional 100% humid air calibration as

described in 100% humid air calibration (high range sensors only) on page 19.

Manual calibration

Manual calibrations can be made at any time by following these steps:

1. Remove the sensor from the sample line.

2. Rinse the sensor head with clean water.

3. Wipe the sensor head with a clean soft tissue to remove any excess moisture.

4. If using the supplied calibration device insert the sensor into the sensor holder on top of the

calibration device. If not using the calibration device insert the sensor into the flow chamber.

5. Flow the calibration sample through the calibration device or flow chamber as applicable. If using

the calibration device fully open the valve on the pressure reducer to give a gas flow rate of

0.1 L/min. If you are not using the supplied calibration device with pressure reducer the maximum

allowable inlet pressure must be no more than 2 bar absolute.

Note: The manufacturer recommends to keep the flow chamber at atmospheric pressure. Adjust the sample

flow before it goes into the flow chamber.

6. Configure the calibration as described in Calibration configuration on page 18.

7. Start the calibration as described in Zero calibration on page 19, 100% humid air calibration

(high range sensors only) on page 19 or High level adjustment on page 20 depending on the

preferred calibration method.

Calibration configuration

Note: This option can also be invoked by pressing the Modify button in either the Zero calibration or High level

adjustment calibration screens.

1. From the Main menu, select Calibration followed by Gas sensor and then Configuration.

Option Description

Auto-calibration Not available for this sensor.

Manual-calibration When Auto-End is enabled a manual calibration will complete automatically when the

parameters defined in Stop parameters are reached. Press on Configure to set the

manual calibration parameters. If the calibration fails, the previous calibration

parameters remain unchanged and a warning message displayed.

Hold during

calibration or

verification

If checked this keeps the last measured value and stops updating the outputs during

the calibration or verification process. This avoids sending invalid information to any

connected device. At the end of a calibration, this hold remains on for a further

10 minutes to allow the system to stabilize.

Option Description

Zero calibration

bottle

Make sure this is disabled by unchecking the box as it is not relevant for this sensor.

Stop parameters If this button is pressed you can view or change the existing values or restore the

default values. It is highly recommended to leave these parameters at their default

values. These values apply to manual calibrations with the Auto-End parameter

enabled.

Configure manual calibration

1. Set the parameters for a manual sensor calibration:

Option Description

Calibration mode Select Zero calibration or High level adjustment. If using a high range sensor you also

have the option of 100% humid air calibration.

Note: If zero calibration or 100% humid air calibration is selected, no other parameters

are required. The following are only required for high level adjustment.

Cal. sample Set to In line sample, Gas bottle or Factory parameters. If factory parameters is

selected, the Ksv value is displayed but can be changed.

These additional parameters are required if in line sample or gas bottle has been

selected as the calibration sample:

Medium This is automatically set to Liquid if in line sample has been selected as the calibration

sample, or Gas if gas bottle has been selected.

Gas unit type Either Partial or Dissolved are available for an in line sample. If gas bottle was selected

this is set to Fraction.

Gas unit The list of available units depends on unit type selected above.

Liquid Select Water for the for the K1100 sensor (default) or Beer for the M1100 sensor.

Reference value Enter the reference value for calibration.

Zero calibration

With this method, the sensor should be removed from the sample and exposed to pure N

2

gas. It is

recommended to use the specially designed portable calibration device for this purpose.

Press Start to start the calibration.

A screen is displayed showing the measured values and length of time the sensor has been under

calibration. These values are continually refreshed.

The value % last calibration is an informational message showing the difference between the

current and previous sensor calibrations.

The Signal within range and Stability reached boxes indicate whether the calibration is within

acceptable limits. When both boxes indicate YES, press Finish to accept the new calibration. If one

or both boxes continue to show NO you can still perform a calibration but it is not recommended

and the calibration should be aborted by pressing the Cancel button.

In the case of a calibration failure, attempt a second calibration after about 5 minutes. If the second

attempt also fails, then refer to your Hach representative for advice.

Note: If the Auto-End parameter is enabled then the calibration will be considered successful when the parameters

defined in Stop parameters are met.

If you have not accepted or cancelled the calibration after an elapsed time of 10 minutes then the

process will time-out.

100% humid air calibration (high range sensors only)

With this method, the sensor should be removed from the sample and exposed to air saturated with

humidity. Do this by putting a drop of water in the calibration cap before installing the cap on the

sensor. Press Start to start the calibration. The process is then the same as for the Zero calibration

described previously.

High level adjustment

Note: Before using this option, ensure a zero calibration has been successfully completed first.

This calibration exposes the sensor to a gas or a liquid sample with a known gas concentration. You

also have the option to reset the sensor’s calibration parameters to factory settings (from drop-down

list for Cal. sample).

Press Start to start the calibration. The process is then the same as for the Zero calibration

described previously.

Barometric pressure calibration

Note: The barometric pressure sensor has been factory calibrated but should be periodically verified with a

precision certified barometer. The barometric pressure is necessary for the O2 sensor calibration. Make sure that

the barometric pressure is correct before the sensor calibration. If necessary, calibrate the barometric pressure.

The upper box shows the barometric pressure as measured by the instrument.

Using a precision certified barometer measure barometric pressure in the location where the

measuring instrument is used. Compare the values and if they are the same press Cancel, otherwise

enter the new barometric pressure value in the lower box and press Validation to validate the new

setting.

Maintenance

Instrument maintenance

C A U T I O N

Personal Injury Hazard. Any instrument maintenance should be carried out by a qualified Hach Service

Technician. Please contact your local representative should you feel any maintenance or instrument adjustments

are required.

Sensor maintenance

The sensor spot needs to be replaced about once a year. The procedure is very simple and takes no

more than a couple of minutes. Based on the measurement range of oxygen, the sensor lifetime can

be shorter and the maintenance—and calibration—frequency increased. If there are bleaching

compounds and strong oxidants (e.g., ClO

2

) in the sample, the sensor lifetime can also be shorter.

Equipment required

1.

A replacement sensor spot

2. The maintenance tool delivered with the sensor

3. O-ring supplied with the sensor spot
