Adjustment examples
1) Input
0…20 mA or 0…10 V
Output
4…20 mA or 2…10 V
Zero point: with zero signal at the input (set 0 mA or 0 V or bridge input), adjust the current or voltage output
with the potentiometer “Zero”.
•
For current output 4…20 mA (terminals 6 and 7) adjust to 4.00 mA,
•
For voltage output 2…10 V (terminals 8 and 7) adjust to 2.00 V.
Full- scale: set the input to max. signal (20 mA or 10 V), adjust the current or voltage output with the
potentiometer “Scale”.
•
For current output 4…20 mA (terminals 6 and 7) adjust to 20.00 mA,
•
For voltage output 2…10 V (terminals 8 and 7) adjust to 10.00 V.
Check zero and Full- scale and repeat if necessary.
