WARNING
The Instrument should only be plugged to an AC outlet with a 90 – 120V voltage range to avoid
damaging the Instrument.
To avoid electrical shock, personal injury, or fire hazard, connect the factory-supplied three-
conductor-line power cord to a properly grounded power outlet.
During test operation, a two-conductor adapter or extension cord MUST NOT be used. This will break
the protective ground connection and will affect the measurement accuracy of the Instruments.
The power outlets supplying the Instrument system should be controlled by an emergency switch so
that power can be switched off if a hazard arises.
2.5 Utility Meter Insertion/Extraction
The electric meter socket requires
zero insertion
force
to mount a meter, as well as to dismount
it, upon pressing the meter release button.
WARNING
When mounting a meter, the Instrument must be
switched OFF. In both mounting or dismounting a
meter, the Instrument should not be performing a
test to avoid electrical shock, personal injury, or
fire hazard.
The meter release button* is only operational
when the Instrument is powered up. No meter can
be dismounted when the Instrument is powered
off.
*When the button lights up in glowing red, it can be
pressed to dismount a meter.
INSERTION:
To load a meter into the socket, ensure meter is oriented properly. Then insert meter into
socket, keeping the meter weight fully supported. The device will automatically clamp to the jaws of
the meter. When the METER RELEASE indicator turns on, the meter is fully supported. Align optical
pickup to meter prior to testing.
EXTRACTION:
To remove the meter from the socket, ensure optical pickup is removed from the face of
the meter. Support the meter shell then press the METER RELEASE button. Once the METER RELEASE
indicator turns off, the meter is safe for removal from the socket.
NOTE:
The socket cannot be powered unless a meter is installed, and if the release button is pressed,
power to the socket will be shut off.
