OPERATING THE TESTER
Safety Instructions
The voltage testers have been designated and tested in
accordance with the safety regulations for voltage testers
when left the factory. To prevent injuries and damages
to the user and the voltage tester, follow the safety
instructions in this manual.
W
Read Before Using:
Danger of electric shock
• To avoid an electric shock, observe the precautions
when working with voltages exceeding 120 V (60
V) DC or 50 V (25 V) r.m.s. AC. In accordance with
general safety regulations these values represent the
maximum allowed limits for contact voltages (values
in brackets refer to limited ranges, e.g. in medical or
agricultural areas).
• The acoustic indication ≥50 V AC and ≥120 V DC is only
to warn the user, not for measuring.
• Before using the voltage tester at locations with a
high background noise level, it should be determined
whether the audio signal is perceptible.
• The voltage tester shall not be used with the battery
compartment open.
• Before using the voltage tester, ensure that the
test lead and voltage tester are in perfect working
condition. Look out for broken cables or leaking
batteries (if applicable).
• The batteries shall be checked before use and be
replaced if necessary.
• Hold the voltage tester and accessories by the
designated probe handle areas only, the LCD screen
and LED indicator must not be covered. Do not touch
the test probes in any case before and during test.
• The voltage tester may be used only within the
specified measurement ranges and in low-voltage
installations up to 690V AC/DC (2100-Gamma: up to
1000 VAC / 1200 VDC).
• The voltage tester may be used only in the
overvoltage category for which it has been designed
for!
• Before and after use, always check that the voltage
tester is in perfect working condition (e.g. check on a
known voltage source or on a proving unit).
• The functioning of the voltage tester shall be checked
shortly before and after a test. If indication of one or
more steps fails, or no functioning is indicated, the
voltage tester must be taken out of operation.
• The voltage tester complies with protection degree
IP 64 (splash-proof and dust-tight) and therefore can
also be used under humid conditions.
• The voltage tester operates correctly only within a
temperature range of -15°C to +55°C at relative air
humidity less than 95% (without condensation).
• If the safety of the user cannot be guaranteed, the
voltage tester must be taken out of operation and
secured against unintentional use.
• Safety is no longer guaranteed in the following cases:
- obvious damage
- if the voltage tester can no longer perform the
required measurements/tests
- stored for too long in unfavorable conditions
- damaged during transport
- leaking batteries
• For all work, observe the accident prevention
regulations of the professional trade association for
electrical installations and equipment and/or other
local safety regulations.
• Unauthorized persons shall not disassemble or
assemble the voltage tester and supplementary
equipment. The voltage tester may be serviced by an
Amprobe authorized service technician only.
• Operational safety is no longer guaranteed if the
voltage tester is modified or altered.
