Setting Interlock Function
4.7 Setting Interlock Function
It is considered to be safe to install the interlock on another installation because the measurement
voltage is not output when a shielding box lid is open.
Use the interlock function for such a case.
The output of measurement voltage and the measurement function are disabled when the interlock
function is activated.
If the interlock setting is set to [ON] while the terminals of the INTER LOCK terminal are open, the
interlock function is activated and the interlock cannot be set to [OFF] on the settings screen.
Either deactivate the interlock (p. 63) or set the interlock setting to [OFF] by using the following
method.
• Turn o󰀨 the instrument once and then turn on it again while pressing both the MENU key and the
down cursor key.
• Send the command
:INTerlock OFF
through the USB, the RS-232C, or the GP-IB
communication.
First, connect the instrument and the shielding box with each other.
See “2.7 For Safe Measurement” (p. 34).
