-
When the peripheral device of the remote current setting is disconnected, measure and
record voltage in the measurement point 3 on the CH21 board in extreme positions of the
local current setting potentiometer.
-
Connect the peripheral device of the remote current setting and set the setting
potentiometer to the minimum value.
-
Using the RP2 assembly potentiometer in point 3 on the CH21 board set the same
voltage as for the minimum position of the local setting potentiometer.
-
Set the setting in the peripheral device to the maximum value and using the RP3
potentiometer, in point 3 on the CH21 board set the same voltage as for the maximum
position of the local setting potentiometer.
