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 Conguration and Signal Types
CH8 CH1
High potential input terminal
Low potential input terminal
BNC connectorScrew 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.
