TC ON The temperature sensor is not
appropriately positioned.
Move the temperature sensor
closer to the measurement tar-
get.
Position the temperature sensor
so that it is not exposed to wind.
If the response to the measure-
ment target’s temperature
change is slower than the tem-
perature sensor’s response,
increase the response time by
covering the temperature sen-
sor with something. The tem-
perature sensor’s response
time is about 10 minutes (refer-
ence value).
p.13
OFF The measurement target’s resis-
tance value is changing due to the
temperature, for example because
the room temperature has not sta-
bilized.
Turn ON temperature correction
(TC).
