CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) DIP switches: Check the output range selector setting.
3) Power input: Check the power input voltage.
4) Input: Check voltage across the terminal B (+) – C (–)
with a voltmeter to show 0 V at the minimum potenti-
ometer input (0 Ω) and the same voltage as that across A
(+) – C (–) at the maximum input.
If the potentiometer wires are broken, the output goes
over 100% (below 0% with downscale protection) due to
burnout function. Confirm the status indicator LED pat-
tern and check leadwires in such a case.
5) Output: Check that the load resistance meets the de-
scribed specifications.
6) Status indicator LED: Check that it blinks in a regular
pattern.
