Electric Field EF-Detection
The meter displays “
EF
” when it is ready. Signal strength is indicated
as a series of bar-graph segments on the display together with
variable beep tones.
v
Non-Contact EF-Detection :
An antenna is located along the
top-right end of the stationary clamp jaw, which detects electric
field that surround energized conductors. It is ideal for tracing
live wiring connections, locating wiring breakage and to
distinguish between live or earth connections.
v
Probe-Contact EF-Detection :
For more precise indication of
live wires, such as distinguishing between Live and Ground
connections, use one single probe to test via terminal
COM
for
direct contact EF-Detection with best sensitivity.

CAUTION & WARNING for Non-Invasive (Clamp-on)
Current Measurements :
CAUTION :
(Application and Removal of the Clamp-on Jaws) For non-invasive
current measurements, press the jaw trigger and clamp the jaws
around conductor(s) of only one single pole of a circuit for load
current measurement. Make sure the jaws are completely closed, or
else it will introduce measurement errors. Enclosing conductor(s) of
more than one pole of a circuit may result in differential current (like
identifying leakage current) measurement. Align the conductor(s) to
TM
the Jaws center indicators (Regular or AmpTip indicators where
applicable) as much as possible to get the best measuring accuracy.
For removal, press the jaw trigger and remove the jaws from the
conductor(s).
Adjacent current-carrying devices such as transformers, motors and
conductor wires may affect measurement accuracy. Keep the jaws
away from them as much as possible to minimize influence.
WARNING :
Do not use the meter to measure currents above the rated frequency
(400Hz). Circulating currents may cause the magnetic circuits of the
Jaws reach a hazardous temperature.
