Operation
Make sure the battery terminals are clean and all electrical connections are good.
Always replace the test probe cover after use.
Current flows through all preceding LED indicators, so the highest indicated voltage
should be taken.
a) Function test / self test
• Before using, perform a test on a known voltage source.
• Do not use if one or several functions fail or if no functionality is indicated.
b) Testing
The “-” polarity LED will light up if
(1)
/
(3)
and
(6)
are connected the wrong way
around.
Batteries / lights
1. Connect the test clamp
(6)
to the
negative
terminal.
2. Use the test probe
(1)
to make contact with the
positive
terminal.
3. The voltage indicator LEDs
(4)
will light up when a voltage is present.
Cables
1. Connect the test clamp
(6)
to the
negative
terminal.
2. Adjust the probe slider
(5)
and wedge the cable inside the cable guide
(2)
.
3. Gently apply pressure to the probe slider to pierce the cable with the punch-through test
probe
(3)
.
4. The voltage indicator LEDs
(4)
will light up when a voltage is present.

service or other technical personnel.
• Measurement instruments used in schools,
training facilities, do-it-yourself, and
hobby workshops should not be handled
unless supervised by trained, responsible
personnel.
b) Voltage tester
•
Only test voltages up to a maximum of
48 V/DC or 48 V/AC. Non-compliance
can lead to serious injury and/or
damage to the test tool.
• Test probe and test clamp may only be
touched at handle surfaces provided.
Absolutely avoid the direct contact of the
test probes.
• Always ensure that the probe and clamp
are dry and never use the instrument when
your hands are wet!
• Prior to usage ensure perfect instrument
function (e.g. on known voltage source).
• Regularly check for damage to the casing,
probes, clamp, and cable. The tester should
never be opened or used if the covers have
been removed. RISK OF FATAL INJURY!
• The instrument should only be used within
the operating ranges as specified in the
