Causes and countermeasures
Dry bulb or wet bulb temperature
has fallen below 0
℃
* Exceeds the conditions for use. Use it at
temperature of higher than 0
℃
Dry bulb or wet bulb temperature
has risen to more than 51
℃
* Exceeds the conditions for use. Use it at
temperature of lower the 50
℃
Operation result of relative humidity
has become less than 0% RH
* Operation function may be abnormal.
* Turn off power switch and turn on again.
* There will be something wrong with the
instrument if it is not restored.
Consult us.
Operation result of relative humidity
has become more than 100%R.H.
* Wet bulb temperature is higher than dry bulb
temperature.
* Check with water level of feed water tank and
check if wet bulb paper string contains water
or not. There is a possibility that this may
occur in atmosphere where the relative
humidity is over saturated.
It is because the instrument is used beyond
the conditions for use.
Operation result of dew point has
become lower than -41
℃
* Exceeds the display range for dew point.
When capacity of battery is not
enough or power source is less
than 90VAC.
* Charge the exclusive battery.
Use the instrument at 100VAC
