CHAPTER 3 Settings and Measurement
Branch adapter for GS (GS-DPA: optional) setting
When the branch adapter for GS is used, the composite measurements with combination of three ways can
be performed.
Combined GS sensor list
Temperature and humidity sensor (GS-TH) Illumination / ultraviolet sensor (GS-LXUV)
Temperature and humidity sensor (GS-TH) CO2 sensor (GS-CO2)
CO2 sensor (GS-CO2) Illumination / ultraviolet sensor (GS-LXUV)
As an example, the setting screen of temperature or humidity sensor (GS-TH) and illumination / ultraviolet
sensor (GS-LXUV) is displayed.
The setting screen is displayed by connecting temperature and humidity sensor (GS-TH) or illumination /
ultraviolet sensor (GS-LXUV) to the branch adapter for GS and turning On the power.
(1)-46 Input setting
This is used to select the input conditions.
When the two types of sensors are connected, the information that can be input to the 1ch to 4ch and 5ch to
8ch is displayed.
In this GL840, 1ch to 4ch correspond to the temperature and humidity sensor and 5ch to 8ch correspond to
the illumination / ultraviolet sensor.
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 ILLUM Used to measure the illuminance.
6ch UV Used to measure the ultraviolet.
7ch ACC. ILLUM Used to measure the accumulated illuminance.
8ch ACC. UV Used to measure the accumulated ultraviolet.
The following shows the CH allocation when connecting a plurality of sensors.
