Brief instructions for EP4 continuity testers
These brief instructions allow to start working with the EP4 continuity tester right
away. For safety reasons, please observe the additional information provided in
the detailed instructions for use.
Switching the continuity tester on
"+1" indicates that the device is operational (as long
as the button is kept pressed when switching on the
device, a self-test is performed)
Zero balancing "CAL" with measuring cable
Press both buttons at the same time.
Connect the measuring cable (any cable up to max. 3
W) to the test prod as long as "CAL"
(about 15 s).
The value is stored and used for
measurements until a new zero balancing is performed.
This value is not deleted if the EP4 continuity tester is
switched on or off.
Selecting a measuring range
In case of resistance values of less than 10 Ω, the EP4
continuity tester automatically switches over to the Lo
Ω mode and measures with a measuring current of 200
mA.
Standard measurement
Standard measurements are performed to measure resi-
stances without storing them. The measured value is dis-
played. "+1" appears again two seconds after a
measurement, meaning that the EP4 continuity tester
is operational.
Change of polarity during standard
measurements
The direction of the measuring current is changed and
displayed by (+) or (-). In case of earth testing with direct
currents, the (+) and (-) values must be determined to
be able to detect incorrect results in case of deviations.
