(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 reflected in the accumulated temperature CH.
3-32
The input signal is not measured. The waveform and digital display also are not performed.
Used to measure the temperature
Used to measure the humidity.
Used to measure the dew-point temperature.
Used to measure the accumulated temperature.
When connecting the two GS series and terminal / addapter using a branch adapter for GS, the
following combination is displayed.
