1. Safety Precautions

Electricity can cause severe injuries even with low voltages or
currents.

Therefore it is extremely important that you read the following
information before using your high voltage insulation tester.

a. This Instrument 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.

b. This instrument must not be used on live circuits. Ensure all

circuits are de-energised before testing. see paragraph for
details of built-in warning features should your high voltage
insulation tester be connected to a live system.

c. Always inspect your high voltage insulation tester and test

leads before use for any sign of abnormality or damage. If any
abnormal conditions exist (broken test leads, cracked case,
display faulty etc...) do not attempt to take any measurement
or use the tester. Return your high voltage insulation tester to
your nearest distributor for service.

d. Your high voltage insulation tester 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.

e. Pay attention to cautions and warnings which will inform you of

potentially dangerous procedures.

f. Your high voltage insulation tester has a live circuit warning

beeper. If it is connected to a live circuit, a rapid pulsating
bleep will be heard. DO NOT proceed to test and immediately
disconnect the instrument from the circuit. In addition your
tester will display the warning message.

2. Overview

This is a variable high voltage insulation tester from 500V to
15kV in 500V steps.

The is menu driven and uses Dynamic Current Auto ranging
technology.

When pressing the on/o󰀨 button, the top line of the display shows

current year, month, date, hour and minutes indication. The
bottom line of the display shows Insulation Meter.

When doing the test, the top line of the display shows Ω reading

and the time duration.

The bottom line of the display shows output voltage and current.

This instrument displays a voltage warning and sounds when AC
or DC is present before injecting the test voltage.

9. Maintenance & repair

(A) To avoid and electric-shock or device damage, do not wet

inner part of the tester.

(B) Avoid the tester from being dropped down that would damage

or disconnect devices apart.

(C) Wipe the tester surface with soft, dry cloth and mild detergent.

Prohibit from using sand paper or solvent.

Note:

1. This tester is HV operated; user should not open the outer
casing. If any damage occurs, take the tester back to
manufacturer for repair.

REMEMBER TO CHARGE THE BATTERY!

ALWAYS recharge the battery when the Low Battery info
appears on the display. Leaving the battery uncharged for a
long period of time may a󰀨ect the lifespan of the battery.

Charging interval: Every 3 months

us. You will find the relevant contact information at the end of this user manual.

15 Disposal

For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament
applies. Due to the contained pollutants, batteries must not be disposed of as household waste.
They must be given to collection points designed for that purpose.

In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use
them or give them to a recycling company which disposes of the devices in line with law.

For countries outside the EU, batteries and devices should be disposed of in accordance with
your local waste regulations.

If you have any questions, please contact PCE Instruments.
