6.5.5. Error in analog output
Status Probable cause Troubleshooting
Current output is not
matched.
Range setting is wrong. Set the range correctly.
Not 4mA when
measurement value is 0.
Analog output is misadjusted. Perform analog output calibration.
Output is 0mA. Break of wiring
Output rises beyond
20mA.
“OVER FLOW” appears on the LCD. Range over
Recommence setting of range data of
analog output.
The output becomes
lower than 4mA.
“UNDER FLOW” appears on the LCD. Back flow
Set upper/lower stream properly.
Indication is changed but
analog output remains

The output load is 600 Ω or more. It must be less than 600 Ω.
Indication does not agree
with analog output.
Analog output is misadjusted. Perform analog output calibration.
Analog output doesn’t
