Dwyer PUX - Manual (Page 85)

11 - 5
State
Output remains at 4mA
though indication value
is other than 0.
Output is 0mA.
Output is not 4mA
when indication value
is 0.
Output rises beyond
20mA.
Analog output remains
the same despite
change in indication
value.
Indication value does
not match analog output.
Output remains the
same even after
calibration of analog
output.
Cause
Analog span setting has not been
made.
Cable is broken.
The zero point of analog output is not
adjusted properly.
Indication value is larger than analog
span value.
Span is deviated.
Output load is larger than 1k
Ω
.
• Zero point and span of analog output
are deviated.
• Hardware error
11.4 Error in analog output
Remedy
Set the span.
Otherwise, output remains at
4mA.
Repair
Calibrate analog output.
Overshoot
Set analog span again.
Calibrate analog output.
Permissible load is 1k
Ω
.
Reduce the load to less than 1k
Ω
.
Calibrate analog output.

11.5 Display of error
Remedy
Select the error check item
"BACKUP BATTERY FAIL"
using the system check page to
display the data of processing the
error, and then perform the
following operation on the
measurement panel.
• When "BACKUP BATTERY
FAIL" is released, set
measurement conditions.
• When "BACKUP BATTERY
FAIL" is not released, the
