Keysight E4981A - Disconnecting from the Supply Source

Keysight E4981A 120 Hz/1 kHz/1 MHz Capacitance Meter 21
Unpacking and Preparation
Starting the E4981A
Disconnecting from the supply source
The plug attached to the power cable (on the power outlet side or device side
of the cable) serves as the disconnecting device (device that cuts off the power
supply) of the E4981A. When the power supply must be cut off to avoid such
danger as electric shock, pull out the power cable’s plug (on the power outlet
side or device side of the cable).
To allow this operation to be performed smoothly, be sure to follow the
guidelines in “Ensuring adequate free space around the capacitance meter
for immediate disconnection of the power cable in case of emergency” on
page 15.
When turning the power OFF under normal circumstances, always follow
the methods described in “Turning the power OFF” on page 20.
