Countermeasure
1)
“Er1”
is displayed in the
main display 1.
Temperature measurement can’t be
executed.
Check the connection of the temperature/humidity sensor.
(Ref. [7. Replacement of temperature/humidity sensor])
Check if dew has been condensed in the temperature/humidity
sensor.
Measurement is possible after recovering from dew condensation.
100%RH has been measured in the
humidity measurement.
Check the connection of the temperature/humidity sensor.
(Ref. [7. Replacement of temperature/humidity sensor])
2) The humidity value in the
main display 2 is 100
%
RH
(The dew-point temperature
display becomes the same
value as the temperature
measured value.).
Interchangeability of the tempera-
ture/humidity sensor has not been
obtained.
Press
∨
key while pressing
∧
key.
(Ref. [7. Replacement of temperature/humidity sensor])
The humidity measurement from 0%RH is possible.
Check if an object is not in absolute dry condition.
0%RH has been measured in the
humidity measurement.
Check the connection of the temperature/humidity sensor.
(Ref. [7. Replacement of temperature/humidity sensor])
3) The humidity value in the
main display 2 is 0
%
RH
(The dew-point temperature
display becomes -60
ºC
.).
Interchangeability of the tempera-
ture/humidity sensor has not been
obtained.
Press
∨
key while pressing
∧
key.
(Ref. [7. Replacement of temperature/humidity sensor])
4)
“Er1”
is displayed in the
main display 2.
Humidity measurement can’t be
executed.
Check the connection of the temperature/humidity sensor.
(Ref. [7. Replacement of temperature/humidity sensor])
5)
“Er2”
is displayed in the
main display 2.
In the dew-point temperature dis-
play, the dew-point computation is
not possible due to abnormal
temperature data.
If
“Er1”
is displayed in the main display 1, check the connection of
the temperature/humidity sensor.
(Ref. [7. Replacement of temperature/humidity sensor])
