2-1 Measured val-
ues are unstable.
TC ON The temperature sensor is not appro-
priately positioned.
→
Move the temperature sensor
closer to the measurement target.
→
Position the temperature sensor so
that it is not exposed to wind.
→
If the response to the measurement
target’s temperature change is
slower than the temperature sen-
sor’s response, increase the
response time by covering the tem-
perature sensor with something.
The temperature sensor’s
response time is about 10 minutes
(reference value).
p.17
OFF The measurement target’s resistance
value is changing due to the tempera-
ture, for example because the room
temperature has not stabilized.
→
Turn ON temperature correction
(TC).
p.75
OVC OFF The measurement is affected by ther-
mal EMF.
→
Turn ON the OVC function.
p.82
2-2 Measured val-
ues differ from
expected values.
(A negative value
is shown.)
Zero-adjustment ON Zero-adjustment is not accurate.
→
Perform zero-adjustment again.
p.68
p.52
OFF Values are being affected by wiring
resistance or thermoelectric power
due to two-terminal measurement.
→
Perform zero-adjustment.
p.68
Scaling function ON The offset setting is incorrect.
→
Turn scaling OFF, or reconfigure
the setting properly.
p.77
p.52
The measurement leads are not con-
nected properly.
→
Check the connections.
