CHAPTER 3 Settings and Measurement
Temperature and humidity sensor (GS-TH: optional) setting
Performs the setting related to the input of temperature and humidity sensor.
The Setting screen is displayed at the end of the group by connecting the temperature and humidity sensor
and turning On the GL840’s power.
(1)-13 Input settings
Setting Description
Off The input signal is not measured. The waveform and digital display also are not performed.
1ch TEMP Used to measure the temperature
2ch RH Used to measure the humidity.
3ch DEW Used to measure the dew-point temperature.
4ch ACC. TEMP Used to measure the accumulated temperature.
5ch to 8ch No AMP When connecting the two GS series and terminal / addapter using a branch adapter for GS, the
following combination is displayed.
Combination CH1 to 4 CH5 to 8
TH+LXUV TH LXUV
TH+CO2 TH CO2
LXUV+CO2 LXUV CO2
Symbols in the table are as follows:
TH: Temperature and humidity sensor
LXUV: Illumination / ultraviolet sensor
CO2: CO2 sensor
(1)-14 Range settings
This is used to select the voltage range to be measured. The temperature range is xed.
Setting Description
TEMP 100℃ xed range
RH 100% xed range
(1)-15 EU setting
The offset of temperature/dew point temperature only can be adjusted.
Refer to “EU Function, Meas. Value, EU Output Value, and Reads the current temperature measurement
value” in “(1)-5 EU (Scaling settings)” in “3.4 Setting Menus”.
Even if the scaling setting is applied to the original measured value of CH, the accumulated temperature is
not reected in the accumulated temperature CH.
