CHAPTER 2 Checks and Preparation
2 .7 Connecting the Input Signal Cables
This section describes how to connect the input signal cables.
When wiring, turn off the signal supply source to prevent electric shock .
Also, position the input cables away from any power lines and ground cables .
Terminal Configuration and Signal Types
CH8
CH1
High potential input terminal
Low potential input terminal
BNC connector
Screw terminal
The screw terminal and the BNC connector are internally connected . You
can measure with either input .
When wiring, turn off the signal supply source to prevent electric shock .
Also, wire as far as possible from the power line and ground cable .
BNC connector
Screw terminal
GL980
The screw terminals of the same CH and the BNC
connector are connected .
Do not input signals to the screw terminal and
BNC connector of the same CH at the same time .
If a signal is input at the same time, the
measurement target device may become
damaged .
When wiring, turn off the signal supply source to prevent electric shock . When applying a voltage of 60V or
more, please use an insulated BNC cable (RIC-142/143/147: Option) sold separately to prevent any electric
shock .
