■ ZERO & SPAN ADJUSTMENTS
After the transmitter is installed and operational, fine zero
and span tuning can be performed as explained below. Both
zero and span are adjustable within ±15%.
1) Run Mode: Confirm that the green LED is blinking
(model M3LU2-x/A) or the green LED turns on (model
M3LU2-x/B).
2) Fine Zero Adjustment Mode: Hold down MODE button
for 1 or 2 seconds until the LD1 red LED is ON and the
LD2 green LED is blinking.
Use UP (increase) and DOWN (decrease) buttons to
adjust the output to 0%.

*1. DC, RTD, Resistance, Potentiometer input: Or ±0.1% of span, whichever is greater.
Thermocouple input: [Accuracy + Cold Junction Compensation Error 1.0°C (1.80.9°F)] or ±0.1% of span, whichever is greater.
For current output, overall accuracy degrades another 0.1% with spans ≤ 2 mA.

3) Fine Span Adjustment Mode: Press MODE button and
confirm that the LD3 green LED instead of LD2 is
blinking.
Use UP (increase) and DOWN (decrease) buttons to
adjust the output to 100%.
4) Run Mode: When fine adjustment is completed, press
MODE button once and confirm that: the LD1 green LED
is blinking in case of M3LU2-x/A; and the LD1 green
LED is ON in case of M3LU2-x/B.
Note 1: Calibration steps can be skipped when not needed by
repeating pushing MODE buttons.
Note 2: There is no stated order of setting 0% and 100% levels
or no limitation of entering values for multiple times
within one step of Calibration Mode. Signal level is
stored each time the respective UP or DOWN button is
pressed.
