FUNCTION 2
Function varies depending on what is selected in the menu.
ZERO
Used to reset the displayed weight to Zero.
TARE
Captures current weight as a tare value, and sets terminal to Net
mode.
CLEAR
When in the net weight mode, press CLEAR to clear the current tare
value; the display will revert to the gross weight value. CLEAR
operates regardless of motion on the scale.
Note that once the tare value has been cleared, it cannot be recalled.
The complete tare process as described above must be performed.

The ZERO and TARE functions will not operate when there is motion on the scale. If one of these keys is
pressed while the scale is in motion, the command will be retained for the programmed number of
seconds while the terminal waits for no-motion. If a no-motion condition is not detected within the
timeout period, the request is cancelled and discarded.

Backlight, adjustment. The procedure for assigning functions to the keys is described below.
1.3.1. Configuring Function Keys
To access the function key assignment interface, press and hold the
or key when in basic
weighing mode. The normal weight display will change to show an array of function icons, as seen
in Figure 1-5. The currently selected function is indicated by a small arrow and a line linking it to
the F1 or F2 symbol. Use the LEFT and RIGHT direction keys ( and ) to position the arrow
next to the desired function. Figure 1-5 shows the X10 function assigned to F1 (left) and the Switch
Units function assigned to F2 (right).

1.4. Basic Functionality
This section provides information the basical functionality of IND231/IND236. The following
functions are addressed in this section:
• Expand x10
• Unit Switch
• Date & Time
• Brightness adjustment
• Zero
• Tare
•
Print
1.4.1. Expand x 10
This icon toggles the weight display between standard and expanded mode. It is used to increase
the selected weight display resolution by one additional digit.
For example, an extra digit of resolution is added to the main weight display, which then changes
from
2.264
to
2.2645
, as shown in Figure 1-6; a star symbol
appears at the left of the weight
display to indicate that the weight value is expanded.
Standard
Expanded
Figure 1-6: Standard and Expanded Weighing Modes
To exit expanded mode, either:
• Wait five seconds; the terminal will automatically return to normal resolution.
Or
• Press the x10 function key again
Printing is disabled when the weight is expanded.
1.4.2. Unit Switching
In order to support locations and applications that require multiple measurement units, the
IND231/IND236 supports unit switching. This is illustrated in Figure 1-7
, which shows the display
switching from
Kg
to
g
. The SWITCH UNITS function enables switching between primary units (the
main unit of measure) and alternate units.
Primary unit is set in the submenu F1.2.1. The second unit is set in the submenu F1.6. More
information, please refer to Chapter 3,
Configuration
.
30100541 | 00 | 08/2013
1-7
English
Figure 1-7: Unit Switching: Kilograms to Grams
When the SWITCH UNITS function is assigned to a function key and that key is pressed, the display
changes from the primary unit to the second unit. Pressing the function key again returns the
display to the primary unit. Each subsequent key press switches between display units.
When units are switched, the units indicator changes to show the selected unit, and the display
value is converted. The display division changes to an equivalent weight value in the switched unit
(for example, from 0.02 lb to 0.01 kg) and the decimal location switches to indicate the
conversion.
When switching units, the capacity of the converted units is dictated by the original number of
divisions established in the capacity and increments area of setup. In some situations, this may
reduce the capacity of the terminal when converting to second unit. If switching would result in a
value that is not supported by IND231/IND236, the unit switch will not occur.
1.4.3. Date and Time
The Date & Time function key is only used to display date or time. Configure the Date & Time in
setup at
F3 - Terminal > F3.3 - Date &Time
. When the function key is first pressed, the time will be
shown. A second press displays the date. The third press returns the display to weighing mode. To
return directly to weighing mode at any time, press the CLEAR
.
1.4.4. Backlight Adjustment
The Backlight Adjustment function key is used to set the brightness of the backlight. There are three
options:
off
,
low
and
high
. Each press of the key moves the backlight to the next setting.
1.4.5. Zero
When a function key is set to ZERO, it has the same effect as the dedicated zero key
.
The Zero function is used to set or reset the initial zero reference point of the terminal. There are
three types of zero setting modes:
• Automatic Zero Maintenance
• Power Up Zero
• Pushbutton Zero
1-8
METTLER TOLEDO IND231/IND236 Quick Guide
30100541 | 00 | 08/2013
Operation
When the scale platform or weighbridge is empty, the terminal should indicate zero. The gross zero
reference is recorded during calibration. If pushbutton zero is enabled in configuration and the
weight is within the zero range, pressing ZERO will capture a new gross zero reference point.
1.4.5.1. Automatic Zero Maintenance
Automatic Zero Maintenance (AZM) enables the IND231/IND236 to reset to the center of zero in
order to compensate for conditions such as terminal or load cell drift or debris on a scale platform.
The AZM operating range is selectable from 0.5, 1, 3 or 10 divisions. Within the configured range,
when the terminal is in a no motion condition, AZM makes small adjustments to the current zero
reading to drive the weight reading toward the true center-of-zero. The feature does not function
when the weight is outside the configured AZM range.
1.4.5.2. Power up Zero
Power up Zero enables the IND231/IND236 terminal to capture a new zero reference point after
power is applied. If there is a motion during power-up zero capture function, the terminal will
continue to check for a no-motion condition until zero is captured.
Power up zero can be disabled or enabled, and a range above and below calibrated zero can be
configured. The range is selectable from +/-2%, +/-10% or +/-20% of capacity and can include a
positive range and also a range below calibrated zero.
1.4.5.3. Pushbutton Zero
The pushbutton (semi-automatic) zero function can be activated by pressing the ZERO key
, by
programming a discrete input, or by issuing a serial command.
Any type of semi-automatic zero can be set to
+/-2%
,
+/- 10%
or
+/- 20%
, relative to the
calibrated zero point.
The semi-automatic Zero command can be initiated via a discrete input, or an ASCII ‘Z’ command
sent serially (in CPTZ and SICS interface modes).
1.4.6. Tare
When a function key is set to Tare, it has the same effect as the tare key .
Tare is the weight of an empty container. A tare value is subtracted from the gross weight
measurement, providing the computation of the net weight (material without the container). The tare
function can also be used to track the net amount of material being added to or removed from a
vessel or container. In this second case, the weight of the material in the container is included with
the tare weight of the container and the display then reflects the net result of any additions to or
subtractions from the vessel.
Tare operations in the IND231/IND236 include:
• Automatic Tare • Clearing Tare
• Tare Interlock • Keyboard Tare
30100541 | 00 | 08/2013
1-9
English
1.4.6.1. Automatic Tare
The IND231 can be configured so that tare is taken automatically (auto tare) after the weight on the
scale exceeds a programmed tare threshold weight. Auto tare can be configured in setup as
enabled or disabled. When auto tare is enabled, the display changes to a zero net weight indication
after the weight exceeds the threshold value. Auto tare operations involve:
Auto tare
threshold Weight
When weight on the scale platform exceeds the tare threshold value,
the terminal automatically tares.
Auto tare reset
Threshold Weight
The reset threshold weight must be less than the tare threshold weight.
When the weight on the scale platform falls below the reset threshold
value, such as when a load has been removed, the terminal
automatically resets the auto tare trigger.
1.4.6.2. Clearing Tare
Tare values can be cleared manually or automatically.
1.4.6.2.1. Manual Clear
Manually clear tare values by pressing the CLEAR key
on the keypad when the
IND231/IND236 is in the net mode and has completed the weighing operation. Motion on the scale
will not impact a manual clear.
If configured in setup, pressing the ZERO scale function key will first clear the tare, then issue a
zero command.
1.4.6.2.2. Auto Clear Tare
The IND231/IND236 can be configured to clear tare automatically when the weight returns to zero
point. Once the tare is cleared, the display returns to the gross weighing mode.
