Rear Panel Detail

The Power Cable and Power Supply Disconnection

The intended power supply disconnect device is the ON/OFF switch that is located on the
Multimeter's rear panel.
The ON/OFF switch must be readily accessible while the instrument is operating. If this
operating condition cannot be met, the power cable plug or other power disconnecting
device must be readily accessible to the operator.
To avoid electric shock and fire hazard, make sure that the power cable
is not damaged, and that it is adequately rated against power supply
network fusing.
If the power cable plug is to be the accessible disconnect device, the
power cable must not be longer than 3 meters.
