1. Safety
Safety Information
To ensure safe operation and service of the
Tester, follow these instructions.
Failure to observe warnings can result in
severe injury or death.
- Avoid working alone so assistance can be
rendered. If the operators safety can not be
guaranteed, the Tester must be removed
from service and protected against use.
- Prior to usage ensure perfect instrument
function (e.g. on known voltage source)
before and after the test.
- Do not connect the instrument to voltages
higher than 750V.
- Do not open the battery cover before take
off from voltage source.
- The safety can no longer be insured if
the Tester :
• 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 (i.e. during transport).
- All relevant statutory safety regulations must
be adhered to when using this instrument.
- The Tester may no longer be used if one
or several functions fail or if no functionality
is indicated or the Tester looks damaged.
- When using this Tester, only the handles
of the probes may be touched do not touch
the probe tips (metal part).
- Do not use the Tester if the Tester is not
operating properly or if it is wet.
- Use the Tester only as specified in the
Instruction card including environmental
conditions and the usage in dry environments
must be followed or the protection by the
Tester might be impaired.
- Use extreme caution when working around
bare conductors or bus bar. Contact with
the conductor could result in an electric
shock.
- Use caution with voltages above 50V AC
rms or 110V DC. These voltages pose a
shock hazard.

DC V
IVT-10 : The safety LED can report a
dangerous voltage> 50 V AC and 120 V DC
IVT-20 : The safety indicator can report a
dangerous voltage > 50 V AC and 120 V DC.
If the tester is used in a noisy
background, you need to ensure that the
soundlevel of the tester is perceptible here.

The Continuity / test is only possible
when batteries are installed and in good
condition.

5. Resistance Measurements
Only on IVT-20
The Resistance test is only possible when
batteries are installed and in good condition.
6. Single-Pole Phase Test
Single-Pole Phase
Firmly →
7
The single-pole phase test is only
possible when batteries are installed and
in good condition.
The single-pole phase test is not always
appropriate for testing whether a circuit is
not live. For this purpose, the bipolar test is
required.
To determine external conductors
during phase tests the display function may
be impaired (e.g. for insulating body
protection or insulating sites).
Firmly grasp the insulated grips of the
Tester probe L2 it is better for increase the
sensitivity of single-pole phase test.
7. Phase Rotation Test
Rotary phase of a three-phase mains
Right rotary field
Firmly →
8
Left rotary field
Testing of phase-sequence direction
is possible from 100V AC voltage (phase
to phase) provided the neutral is earthed.
On making contact with both test electrodes
(probe tips) to two phases of the three-phase
power supply which are connected in clock-
wise rotation, a “B” symbol appears in the
LCD Display.
If the rotation is anticlockwise, then a “C”
symbol is displayed. In this case both phases
of the unit should be switched around.
Note :
Testing the phase rotation always requires a
negative phase rotation test!
To ensure a connect test, it is better to test
on a known source.
Firmly →

Attention :
Please ensure that the test electrodes (probe
tips) make good contact with two phases of a
three-phase mains while testing the phase
rotation. For absolute determination of a clockwise phase rotation it is necessary to make a
negative phase rotation test after changing the
phases. The indication “B” or “C” can be
affected by unfavorable light conditions, by
protective clothing or in insulated locations.
Firmly grasp the insulated grip of the Tester
probe L2, it is better for the sensitivity of the
phase rotation test.
8. RCD Voltage Test
Voltage Test with RCD Trip Test
During voltage tests in systems equipped with
RCD circuit breakers, a RCD switch can be
tripped at a nominal residual current of 10mA
or 30mA by measuring the voltage between L
and PE.
These Testers IVT-10 / IVT-20 are equipped
with an internal load enabling the tripping of
an RCD protection device of 10mA or 30mA.
10
To avoid RCD tripping, a test has to be
carried out between L and N during approx.
5sec. Immediately afterwards, voltage testing
between L and PE can be carried out without
RCD tripping.

If the instrument shows failue, please don’t
use it and send it to our service department for
repair.

12. Battery Replacement
If no signal sound is audible (IVT-10) when
short circuiting the test probes, if the symbol
“<” is displayed (IVT-20)
- Completely disconnect IVT-10 /IVT-20 from
the measurement circuit.
- Unscrew the screw by a cross screw driver,
then open the battery cover.
- Remove discharged batteries.
- Replace by new batteries, type 1.5V
IEC LR03 by respecting correct polarity.
- Close the battery cover and re-screw the
screw.

14. Cleaning
Prior to cleaning, remove the instruments
from all measurement circuits.
If the instruments are dirty after daily usage,
it is advisable to clean them by using a damp
cloth and a mild household detergent. Never
use acid detergents or dissolvent for cleaning. After cleaning, do not use the voltage
tester till it is dried completely.
15. Transport and Storage
In order to avoid instrument damage,
it is advised to remove batteries when not
using the instrument over a longer period.
The tester must be stored in dry and closed
areas. In the case of an instrument being
transported in extreme temperatures, a
recovery time of minimum 2 hours is
required prior to instrument operation.
16. Maintenance
Unauthorized persons shall not disassemble
the tester and the supplementary
equipment.
When using tester IVT-10 /IVT-20 testers in
compliance with the instruction manual, no
particular maintenance is required.
If functional errors occur during normal
operating, our service department will check
your instrument without delay.
