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 device.

Note:

The produce

r 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 voltage

and the continuity of connections as well as meas-

urements of resistance. In order to guarantee the

correct operation of the device and correctness of

the obtained results observe the following recom-

mendations:

•Before operation of the device starts, get your-

self acquainted with the present manual and the

safety rules and regulations as well as the rec-

ommendations specified by the manufacturer.

•Any other application of the device which has

not been determined within the present manual

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 electric in-

stallations. Should the tester be operated by un-

authorised persons, there is a danger of dam-

age to the device and the user.

•The device must not be applied to the network

and equipment within premises of special condi-

tions, e.g. in a dangerous atmosphere with re-

gard 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. ex-

cessive humidity). If the meter has been

transferred from a cool to a warm environ-

ment of a high level of relative humidity, do

not realise measurements until the meter

has been warmed up to the ambient tem-

perature (approximately 30 minutes).

•Do not operate a meter with an open or incor-

rectly closed battery (accumulator) compartment

or power it from other sources than those speci-

fied 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.

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 ap-

pear 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

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 measure-

ment 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 between

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 (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 upper

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 normal

measurement mode, they must press the HOLD

button again.

In the HOLD mode the Auto-OFF time will be

extended to 30 seconds.

2.8 Phase order test

Note:

The order of the phases may be determined so-

lely 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 condi-

tions (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 approxi-

mately seven seconds.

The illumination may be also turned on when the

tester is off, and then three lines will appear on the

display.
