*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
On Voltage or Current functions, hold down the
EF
button for one second or
more to toggle the 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 in the top-right of the
meter, which detects the electric field of 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 is equiped with an optically isolated interface port on the rear for
data communication. Hold down the
HOLD
button while turning the meter on to
enable the PC-COMM output. The optional PC interface kit ACT/6000IK is
required to connect the meter to your PC`s RS232 or USB ports.
