SAFETY NOTES
Reference. Please use utmost attention.
Do not exceed the maximum allowable input
range of any function
Insulated personnel body protective equipment
up to 690V.
WARNINGS
In order to avoid electrical shock, the valid safety
and VDE regulations regarding excessive contact
voltages must receive utmost attention, when
working with voltages exceeding 120V (60V) DC or
2
50V (25V) rms AC. The values in brackets are valid
forlimited ranges (as for example medicine and
agriculture).
Prior to measurement ensure that the test leads
and the test instrument are in perfect condition.
When using this instrument only the handles of
the probes may be touched – do not touch the
probe tips.
This instrument may only be used within the
ranges specified and within low voltage systems up
to 690V.
Prior to usage ensure perfect instrument function
(e.g. on known voltage source).
The voltage testers may no longer be used if one or
several functions fail or if no functionality is
indicated.
Do not use this instrument under damp conditions.
Perfect display I sonly guaranteed within a
temperature range of -10℃up to +55℃, at relative
humidity question <85%.
If the operator’s safety cannot be guaranteed, the
instrument must be removed from service and
3
protected against use.
The safety can no longer be insured if the
instrument:
Shows obvious damage
does not carry out the desired measurements
has been stored for too long under unfavorable
conditions
has been subjected to mechanical stress
during transport.
All relevant statutory regulations must be adhered to
when using this instrument.
Appropriate Usage
The instrument may only be used under those
conditions and for those purposes for which it was
conceived. For this reason, in particular the safety
references, the technical data including
environmental conditions and the usage in dry
environments must be followed.
When modifying or changing the instrument, the
operational safety is no longer ensured.
The instrument may only be opened by an
4
authorized service technician, e.g. for repair.

Explanations of Symbols
The voltage tester shows the following symbols:
Inserting/Changing the Batteries
The voltage tester is operated with two
micro-batteries (type AAA, in the scope of delivery).
Proceed as follows to insert or change the batteries:
• Loosen the screw on the battery compartment
DC DC voltage
AC AC voltage
DC voltage negative potential (DC)
Phase display from 100 to 690V ~ 50/60Hz
when used as a „single-pole“ phase tester.
Continuity test symbol
Rotating field display clockwise
Rotating field display anticlockwise
Device for work to be performed with voltage
present
Battery replacement symbol

lid (9) with a suitable screwdriver
and remove it.
• Insert two micro-batteries (AAA)
into the
battery compartment. Observe
the polarity
information in the battery compartment.
If possible, use alkaline batteries.They guarantee a
longer service life.
• Then, carefully close and screw down the battery
compartment lid again. The batteries need to be
changed if the „Low Bat “symbol lights up on
the LCD display or when the LCD display stays dark
after contacting both test tips.
The voltage tester will show no reading if
the batteries are flat. The device must not be
operated with flat batteries or without batteries.
To prevent damage to the device from leaking
batteries, remove the batteries from the device if
you will not be using it for a longer period. For the
9
same reason, we recommend that you remove flat
batteries immediately.
Function test / Self test:
Test the voltage tester on a known source.
Warning: To avoid electric shock, disconnect
the test leads from any source of voltage
before turn on the self-check test function.
The “!” LED will light on when there is a
voltage over 50V, even if the battery is low or
if the battery has been removed.
When press “Autotest” button, all the
bargraph will must be light on, and LCD
display “000” ,and The continuity test’s LED
(6) will light on, buzzer sound. This shows
the tester self-test was done.
Measuring Point Lighting
The voltage tester has a battery-operated
measuring point lamp. Press button (8) to switch
this lamp on. The lamp stays on
as long as this button is kept pressed. When the
button is released, the lamp goes off.
