Status Indicator Led - M-system M3LR Instruction Manual

■ 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 M3LR-x/A) or the green LED turns on (model
M3LR-x/B).
2 ) Fine Zero Calibration Mode: Press MODE button for 1
or 2 seconds until the LD1 red LED is ON and the LD2
green LED is blinking.
3 ) Use UP (increase) and DOWN (decrease) buttons to
adjust the output to 0%.
4 ) Fine Span Calibration Mode: Push MODE button and
confirm that the LD3 green LED instead of LD2 is
blinking.
5 ) Use UP (increase) and DOWN (decrease) buttons to
adjust the output to 100%.
6 ) Run Mode: Push MODE button and confirm that only
the LD1 green LED is blinking.
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 multi-
ple times within one step of Calibration Mode. Sig-
nal level is stored each time the respective UP or
DOWN button is pressed.
