Analog Output
The analog output of resistance measurement values is recorded by connecting
the analog output to a recorder to record the changes in resistance values.
⚫
To avoid electric shock and instrument malfunction, please set the power
supply of this instrument and the connected instrument to OFF when
connecting the analog output terminal.
