Thank you for having purchased our voltage tester.
The P-2 tester is a modern, high-quality measure-
ment instrument, which is easy and safe to use.
However, reading the present manual will permit
you to avoid measurement errors and prevent
possible problems regarding operation of the de-
vice.
Note:
The producer reserves the right to realise
modifications as regards the appearance of
the device, its equipment and technical data.

1 Safety
The purpose of the P-2 device is to test volt-
age and the continuity of connections as well as
measurements of resistance. In order to guarantee
the correct operation of the device and correctness
of the obtained results observe the following rec-
ommendations:
•Before operation of the device starts, get your-
self acquainted with the present manual and
the safety rules and regulations as well as the
recommendations specified by the manufac-
turer.
•Any other application of the device which has
not been determined within the present man-
ual may cause its damage and constitute a
source of danger for the user.
•The device should be operated solely by quali-
fied personnel who are properly authorised
and certified to realise measurements in elec-
tric installations. Should the tester be operated
by unauthorised persons, there is a danger of
damage to the device and the user.
•The device must not be applied to the network
and equipment within premises of special con-
ditions, e.g. in a dangerous atmosphere with
regard to explosion or fire.
•It is unacceptable to operate the following:
⇒A damaged meter which is completely or
partially out of order,
⇒A meter with damaged cable insulation,
⇒A meter stored for an excessive period of
time in disadvantageous conditions (e.g.
excessive humidity). If the meter has been
transferred from a cool to a warm envi-
ronment of a high level of relative humid-
ity, do not realise measurements until
the meter has been warmed up to the
ambient temperature (approximately 30
minutes).
•Do not operate a meter with an open or incor-
rectly closed battery (accumulator) compart-
ment or power it from other sources than those
specified in the present manual.
•Do not realise measurements for more than 30
seconds. After a 30-second measurement, the
next measurement may be realised not sooner
than after 240 s.
•The purpose of the signalling of limit values is
solely to warn the user and not to realise a
measurement.

5
Note:
The device may also be used during rain,
however at user’s own responsibility. It is
recommended to use gauntlets.
2 Measurements
2.1 Control of operation of the
tester
Before each use of the tester, it is necessary
to control its operation:
•The voltage indicator must be tested using a
known source of voltage,
•Close the measurement probes – there
should be an audible acoustic signal, the
LED Ωdiode should be on and the symbol
should appear on the display.
Remarks:
The voltage indication function is active when
the batteries are discharged or without batteries. In
order for the remaining functions to be active
charged batteries are required.
2.2 AC or DC voltage test

6
Note:
In the networks protected with an RCD switch
whose nominal current is 10mA or 30mA, it is pos-
sible that the switch is activated during a meas-
urement of voltage between L and PE. In order to
avoid that connect the tester between L and N and
after approximately five seconds switch the probe
from N to PE.
2.3 RCD operation test
In order to check the operation of the RCD
switch whose nominal current is 10mA or 30mA it
is necessary to realise a voltage test directly be-
tween the L phase and the protective cable PE.
2.4 One-pole phase testing
Note:
Attention!
Do not touch the electrode of the measurement
probe L1 during the testing of the phase.
In the case of one-pole determination of
phases for the purpose of specification of external
cables, under certain circumstances it is possible
that the operation of the tester will be impaired

7
(e.g. using insulated personal protection means or
in the case of an insulated work station).
One-pole phase testing may not be a sufficient
means to determine whether the circuit in question
is live. Do apply the two-pole voltage test.
2.5 Circuit continuity test
Note!
The measured object may be live.
Connect both the probes to the measured ob-
ject. An acoustic signal, lit Ωdiode and the symbol
appearing on the display indicate continuity
of the circuit (R<600kΩ).
Note:
During the measure of continuity polarization
of the voltage at the L2 probe is negative.
2.6 Measurement of resistance
Note!
The measured object may not be live.
Press shortly the Ωbutton and connect both
the probes to the measured object. Read the result
from the LCD display.
Note:
During the measure of resistance polarization
of the voltage at the L2 probe is negative.
2.7 The HOLD function
The purpose of the present function is to hold
the result of the measurement o the display. It is
possible pressing the HOLD button. In the left up-
per corner the
HOLD
symbol will be visible all the
time while the measuring instrument remains in
this mode.
Should the operator want to return to the nor-
mal measurement mode, they must press the
HOLD button again.
In the HOLD mode the Auto-OFF time will be
extended to 30 seconds.

8
2.8 Phase order test
Note:
The order of the phases may be determined
solely in a three-phase system.
2.9 Illumination of the measured
point
The P-2 tester offers the possibility of illumina-
tion of the measured area under difficult light con-
ditions (e.g. in switchgears). In order to illuminate
the measured point press the button marked with
the symbol . At the same time the LCD display
is backlit and it turns off automatically after ap-
proximately seven seconds.
The illumination may be also turned on when
the tester is off, and then three lines will appear on
the display.

3 Replacement of the batter-
ies
The tester is powered by means of two 1.5V
AAA batteries. A lack of acoustic signal once both
the probes have been closed, too weak illumina-
tion after the button has been pressed or the
symbol appearing on the display indicate the
necessity to replace the batteries. Follow the in-
structions below:
- disconnect the probes from the measuring circuit
- using a tool or a coin unscrew the battery com-
partment anti-clockwise and remove it
- replace batteries observing the polarity
- replace the compartment and screw it clockwise
4 Cleaning and maintenance
NOTE!
Use solely the method of maintenance speci-
fied by the manufacturer in the present manual.
The tester may be cleaned with a soft, wet
flannel using al-purpose detergents. Do not use
any solvents or cleansing agents which might
scratch the casing (powders, pastes, etc.).
The electronic system of the tester does not
require maintenance.
5 Storage
Storing the tester observe the following rec-
ommendations:
•Place protectors on the probes,
•Make sure the tester is dry,
•In the case of prolonged periods of storage
remove the batteries from the tester.

10
6 Dismantling and utilization
Worn electric and electronic equipment must
be disposed of selectively, i.e. it must not be dis-
posed of along with waste of other kinds.
Send worn electronic equipment to a collection
point in accordance with the act on worn electric
and electronic equipment.
Before sending the equipment to a collection
point do not dismantle any components of the
equipment.
Observe local regulations regarding disposal
of packages, discharged batteries and accumula-
tors.
