When you set 0% or 100% input/output ranges,
keep pressing UP or DOWN button until the
LD1 flashes for approx. 5 seconds and turns off,
which indicates the setup is complete.
When you release the button, the LD1 is returned
to ON.
If the LED does not change, the entered level may
be inappropriate: e.g. out of usable range.
*For the model M3LPA2-x/A, the green LED is blinking.
For the model M3LPA2-x/B, the green LED turns on.
In order to change the threshold, apply simulated
100% input signal and push UP (increase) or DOWN
(decrease) buttons until the output meter shows
100% output signal as in the example below.
When polarity is set to Bipolor, because the internal
threshold level is fixed to 0V, the threshold calibration
mode does not function.
[Example]
Input range: 0 to 100 Hz
Output range: -10 to +10V
Apply 100 Hz and the output meters must show +10V.
Once the transmitter
enters the fine zero
calibration mode,
the output goes to
preadjusted 0%
value regardless
of the present input
signal.
Once the transmitter
enters the fine span
calibration mode,
the output goes to
preadjusted 100%
value regardless
of the present input
signal.
