CHAPTER 3 Settings and Measurement
(1)-27 Logic / Pulse setting
This is used to perform the setting related to the digital input to the GL840.
Refer to “(1)-7 Logic/Pulse” in “3.4 Setting Menus”.
However, for Group settings, LOGIC5 to LOGIC8 and PULSE5 to PULSE8 are displayed.
When the pulse is measured by the GL100-WL or GS sensor, the pulse measurement is executed in GL100-
WL or GS sensor side.
The fastest sampling speed of the GL100-WL and GS sensor is 500 ms.
When the sampling speed of the GL840 is faster than 500 ms, there is a possibility that the error between
the value captured in 500 ms by the GL100-WL and GS sensor and the pulse captured by the GL840 may
occur, in order to execute the calculation processing within the sampling interval of GL840.
4ch Thermistor Terminal (GS-4TSR: optional) setting
Performs the setting related to the input of 4ch thermistor terminal.
The Setting screen is displayed at the end of the group by connecting the 4ch thermistor terminal and
turning On the GL840’s power.
(1)-28 Input setting
This is used to select the input conditions.
Setting Description
1ch to 4ch Off The input signal is not measured. The waveform and digital display also are not performed.
TEMP Used to measure the temperature.
5ch to 8ch No AMP Because the amplier cannot be installed, the “No AMP” is displayed.
