1. Safety Precautions
Electricity can cause severe injuries even with low voltages
or currents. Therefore it is extremely important for you to
read the following information before using your High
Voltage Proving Unit for Voltage Testers.
1.1 This Proving Unit must only be used and operated by
a competent trained person and in strict accordance with
the instructions. We will not accept liability for any damage
or injury caused by misuse or non compliance with
instructions and safety procedures.
1.2 Never open your High Voltage Proving Unit for Voltage
Testers except for battery replacement.
(See Battery replacement).
1.3 Always inspect your High Voltage Proving Unit for
Voltage Testers and test leads before use for any sign of
abnormality or damage. If any abnormal conditions exist
( broken test leads, cracked case, etc... ) do not attempt to
take any measurement or use the tester. Return your High
Voltage Proving Unit for Voltage Testers to your nearest
Distributor for Service.
1.4 Your High Voltage Proving Unit for Voltage Testers has
been designed with your safety in mind. However, no design
can completely protect against incorrect use. Electrical
circuits can be dangerous and/or lethal when a lack of
caution or poor safety practice is used. Use caution in the
presence of voltage above 24V as these pose a shock
hazard.
1.5 Pay attention to the cautions and warnings which
will inform you of potentially dangerous procedures.

The High Voltage Proving Unit for High Voltage testers
is utilized to determine if the devices under test are
functionally working.
The High Voltage Proving Unit is not a calibrator and
can’t be utilized for calibration.
The High Voltage Proving Unit for High Voltage testers
can be utilized to proof contact devices on a momentary
basis (press on, check, release).
3. Features

be used with non contact proximity detectors).
- High Voltage Testers
● Battery Operated.
● Led indicates when Power is "ON"
● Small and Hand Held.
● Quick connection with normal 4mm Test Leads.
● Comes in a pouch (standard).

7. Proofing Methods
Proofing PC xxk - Multifunction Voltage Testers
The Master Pole must be
connected to the positive
socket of the proofing unit.
The Slave Pole must be connected to the negative socket
of the proofing unit.
The Test button of the proofing unit must be depressed for
a short time only. During that short time, the neon voltage
detector must lit and the panel meter must deviate and show
increase in the voltage, then come back down.
Proofing PE xxk - Voltage Testers
The Master Pole must be
connected to the positive
socket of the proofing unit.
The Earth Prod (or Earth wire) must be connected to the
negative socket of the proofing unit.
The Test button of the proofing unit must be depressed for
a short time only. During that short time, the neon voltage
detector must lit and the panel meter must deviate and show
increase in the voltage, then come back down.

The High Voltage Proving Unit for Voltage Testers output
a DC Voltage of around 5000Vdc (factory setting).
This unit has been designed to deviate most of the voltage
Testers and the Voltage detectors. It can be used with most
of the phasing sticks and voltage testers which can accept
5000V input.
This unit is basically a low current 5000Vdc supply.
The output current is limited. To save battery life, it is
recommended to depress the TEST button for short period
of time only.

or compatible models
8. Preparation for Proving.
Before testing Always Check the Following.
At Power "ON", check :
- The led lit. If the led does not lit, replace Batteries.
- There is no visual damage to the tester or Test leads.
- Test lead continuity with a meter.
9. Battery Replacement
Your High Voltage Proving Unit for Voltage Tester's batteries
are situated under the tester.
Disconnect the Test leads from the tester, remove the battery
cover and the batteries.
Replace with six 1.5V R6 or L6 batteries (ALKALINE TYPE
ONLY), taking care to observe correct polarity.
Replace the Battery cover.
-7-
10. Servicing and Calibration
Your High Voltage Proving Unit for Voltage Tester has
been factory Calibrated.
However, it is of good practice to have your tester
"CHECKED" every year by an professional Workshop.
11. Cleaning and Storage
Periodically, wipe the case with a damp cloth and detergent;
do not use abrasives or solvents.
If meter is not to be used for periods longer than 60 days,
remove the batteries and store them separately.
WARNING
To avoid electrical shock or damage to the meter,
do not get water inside the case.
