*Note: When measuring a 3-phase system, special attention should be taken to the
phase-to-phase voltage which is significantly higher than the phase-to-earth voltage. To
avoid exceeding the voltage rating of the protection fuse(s) accidentally, always
consider the phase-to-phase voltage as the working voltage for the protection fuse(s).
Electric Field EF-Detection
At Volt or Current function, press the
EF
button for one second or more and release to
toggle to EF-Detection feature. The meter displays “E.F.” when it is ready. Signal
strength is indicated as a series of bar-graph segments on the display plus variable
beep tones.
Non-Contact EF-Detection:
An antenna is located along the top-right end of the meter,
which detects electric field surrounds current-carrying conductors. It is ideal for tracing
live wiring connections, locating wiring breakage and to distinguish between live or earth
connections.
Probe-Contact EF-Detection:
For more precise indication of live wires, such as
distinguishing between live and ground connections, use the Red (+) test probe for
direct contact measurements.
PC computer interface capabilities
The instrument equips with an optical isolated interface port at the meter back for data
communication. Press
HOLD
button while turning the meter on to enable meter PC-
COMM output. Optional purchase PC interface kit AMD 9025 is required to connect the
meter to the PC computer RS232 or USB ports.
Hold
The hold feature freezes the display for later view. Press the
HOLD
button
momentarily to toggle the hold feature.
