6.6.5. Error in analog output
Status Probable cause Troubleshooting
Current output is not
matched. Range setting is wrong. z Set the range correctly.
Not 4mA when
measurement value is 0. Analog output is misadjusted. z Perform analog output calibration.
Output is 0mA. Break of wiring
Output rises beyond
20mA. “OVER FLOW” appears on the LCD. Range over
z Recommence setting of range data of
analog output.
The output becomes
lower than 4mA. “UNDER FLOW” appears on the LCD. Back flow
z Set upper/lower stream properly.
Indication is changed but
analog output remains
the same. The output load is 1 k ȍ or more. z It must be less than 1 kȍ.
Indication does not agree
with analog output. Analog output is misadjusted. z Perform analog output calibration.
Analog output doesn’t
change even after it has
been adjusted. Hard failure z Contact manufacture for service.
