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.

(G) Introduction of other functions
1. Dielectric absorption ratio (DAR):
Ratio of insulation resistance between 1-min and 30-sec
1-min insulation resistance
DAR :
30-sec insulation resistance
2. Polarization index (PI):
Ratio of insulation resistance between 10-min and 1-min
10-min insulation resistance
PI :
1-min insulation resistance
Operation:
During the test run, wait for one minute, DAR will be
displayed automatically; wait for 10 minutes, PI will be
displayed automatically.
3. AUTO OFF:
System will shutdown automatically after 3 minutes without
operation.
Lower insulation resistance tested takes longer test
time, which would deteriorate the specimen. Thus,
higher DAR or PI (as close to 1) would create better
insulation grade of specimen.

8. Charge
(A) Timing:
After "Low Battery" is displayed on LCD display, perform
battery charge; LCD displays the picture shown in below:
(B) Process:
1. Plug one end of charger into the battery plug-in socket (Fig
⑬); and the other end into the ACV power socket.
2. If ACV plug socket is energized, the charge indicator (Fig
⑭) is lit on indicating that charge is underway.
If the ACV plug socket isn’t energized, remove to another
power-energized one making power charge.
3. After the voltage reaches 16.5V, charge process is
complete. (It can be observed on LCD display.)
No measurement can be performed during the charging
process.

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.
