SAFETY RULES
CAUTION RISK OF ELECTRIC
SHOCK
This 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 lack of caution or poor safety practices are
used.
Do not carry out field measurements on either the power system grounding,
during periods of forecast lightning activity, in areas that encompass the
station being measured or of the power network connected to the station
being measured. In the event that lightning occurs, stop all testing and
isolate any temporarily installed test spikes.
Preparations for testing of power system grounding can leave personnel
vulnerable to exposure caused by faults at or fed from the system under test,
transferred potentials from remote test grounds, and inadvertent line
energisations.
While the probability of the occurrence of one of these events is low,
personnel safety will, nevertheless, be enhanced by the following:
When working near high tension systems rubber gloves and shoes
should be worn.
Work on clean, dry crushed rock or an insulating blanket.
Avoid bare hand to hand contact between the tester and extended test leads.
When using the tester with test leads, ensure that they are safe and properly
authorized
Disconnect the tester from any external circuit when checking or changing
the Fuse and/or batteries.
Follow the instructions in the Manual for every measurement. Read and
understand the general instructions before attempting to use this tester

SAFETY CHECK
Before using the tester check the condition of the test leads and the fuses.
The test leads must be free of cracks or any damages and must be insulated
as when they were new.
Fuse replacement is described later in this user's manual..
When changing the fuses by removing the cover to access the internal
circuitry, always disconnect the test leads.
When replacing the fuse use only the type specified, HBC fuse, and insert
correctly into the fuse holder.
Always double check the lead connections before making any
measurements.
For increased safety, use fused test leads (optional).
DON'T TOUCH
Don't touch exposed wiring, connections or other "Live" parts of
an electrical circuit. If in doubt, check the circuit first for voltage
before touching it.
Do not use cracked of broken test leads.
THIS INSTRUMENT SHOULD ONLY BE USED BY A
COMPETENT, SUITABLY TRAINED PERSON.

BRIEF PRODUCT DESCRIPTION
The Insulation Tester has all the basic features needed to check and certify
an electrical installation. The buzzer feature is always ON.
The Batteries are tested at startup.
It complies to all good Standards.
The Test Button is utilized to switch the Instrument On as well as
to start or stop the test.
It is also utilized to accept a selection and to disable the EnerSave feature.
In order to use te PI and DAR function on this tester, the EnerSave need to
be disabled.
To disable EnerSave, the user need, while starting a test, to depress the
TEST key for more than 3 Seconds.
After 3 Seconds, a short beep will be heard, meaning that EnerSave has
been disabled.
Once EnerSave is disabled, the test duration can go for as long as 10
minutes.
At any time, the test can be stopped by depressing the Test key again.
The Ohm Key is a multi-purpose key, you press it to select the Continuity
Test, then you use it too to Auto-mull the test leads and fuse
There is an automatic Voltmeter which is accessed after start up.
The Voltmeter is the default mode of this instrument.
For Insulation Testing, the user can select the test voltage of 250V, 500V and
1000Vdc.

The Multifunction Tester has the features of the Insulation Tester plus the
MOV and GAS Arrester Test.
To access the MOV test, You need the depress the 1000V and
500V keys Simultaneously And To access the GAS
Arrester Test, you need to depress the 250V and Ohm Key
simultaneously.
The Multifunction Tester has everything
You'll ever Want from an electrical
Test and Measuring tool.
Before any test is performed, (provided
the test leads are connected properly and
the fuse is intact) it make a voltage test to
assert that there is no voltage on the device or
circuit under test.
If there is a voltage which could be a problem for the test, the tester,
automatically, switch to the Voltmeter and shows the voltage on the display.
Be it AC or DC.
If voltage is present on the leads before test is started, the selected test is
cancelled and the keypad is disabled, preventing errors of operation. This
makes this tester one of the safest to operate to date.
Once any voltage is cleared, test can begin. Should you want to measure
Insulation Resistance, you can select by using the 250V, 500V and the 1kV
test Voltage which all go into the Giga-Ohm range. Should you want to test
continuity, use the Low ohms scale, down to 0.01Ohm and also the buzzer.
You can null the fuse and test leads using the Auto-Null feature. Of Course
on this model, Auto-hold is featured. You will appreciate the superior Safety
of Auto-Hold when you decide to visually look after your arms and fingers
without needing to check the display. Auto-Hold is always turned ON and
with it, you can simply touch the voltage and remove the test probes. The
last valid voltage will be on the display when you want to see it.
While Dangerous voltages are present on the leads, it beep too, signalling
the user that he is touching dangerous voltage.

FEATURES
ON Key.
When Depressing the ON button, the tester starts up. The tester will
automatically make a battery test (under load condition) and display the
results.
After that, the voltmeter is automatically selected. If voltage is present, the
tester will automatically display it on the display and disable all other features
until the voltage is removed from the terminals.
Battery Test
There is no battery Key, but a Controlled Load is switched ON
automatically during starting of the tester.
That Load draw some current from the battery.
While drawing that current, the battery voltage is measured and displayed.
To do an other "under load" battery test, you will need to re-start the tester.
The battery is monitored constantly while the tester is operating. Should
the battery be low, the low battery indicator will lit up on the display.
Voltmeter
There is no Voltmeter Key as this is the default mode of this instrument.
The tester switch to the voltmeter mode after start-up.
This is an automatic AC/DC voltmeter.
This mode is the default mode of the tester, meaning that it's monitoring
the leads before any test is started and also monitoring the leads at Switch
ON of the tester.
The voltmeter is also activated during automatic discharge of circuit after
an Insulation test.
Auto-Hold
Auto-Hold feature is always ON (displays Auto Hold on the LCD), the
tester automatically hold the last valid reading present on the test leads.
This is a very good feature for added safety. That mean that the user can
focus on his test leads and what they are touching instead of looking at the
display.
The voltmeter is like an automatic Hold.
This feature has been developed by Toptronic Limited so that the user can
focus on his personal safety first.
The value will be held on the LCD for later reading after the leads are
removed from Dangerous voltage and situations.

250V, 500V, 1kV Insulation Resistance Tests
When an Insulation Resistance Test is selected, the first thing the tester
requires, is for you to connect the leads to the circuit under test. If the circuit
is not voltage free, the tester will go back to the safety voltmeter until you
insulate the circuit under test from any voltage source.
If the circuit under test is voltage free, then you will be asked to confirm
that you want to test it now, then the test will start. You can observe the
voltage output on the bar-graph and see the Insulation resistance results.
Test can be stopped at any time or automatically, according to the type of
test started and the duration you depressed TEST (see EnerSave Mode)
TEST Key
The Test Key is utilized to start and stop the test.
This is in conjunction with EnerSave™.
EnerSave™feature
When you depress the TEST key to turn the selected test ON. The tester
will automatically stop the test for you after about 10 Sec, but if you whish to
keep the test running much longer, then depress and keep depressing the
TEST key for more than 3 Seconds, the tester will beep when EnerSave™is
disabled.
For longer tests duration, every time you start a test, you need to keep
depressing the TEST key for more than 3 Seconds to disable EnserSave™.
EnerSave™is the default setting of these testers. EnerSave™was
developed by Toptronic Ltd to help reduce Consumption by reducing the test
duration automatically.
Ohm Key for Continuity Tests
Select the ohm key to make Continuity tests. Continuity test has a short
circuit current of more than 200mA. That range can measure down to
0.01Ohms.
Use this feature with Auto-Null for Convenience.
Auto-Null Key for Continuity Tests (same key as ohm key)
You must depress the ohm key to auto-null the resistance of the test leads
and the resistance of the fuse. Once this is done, that auto-null value is
saved internally and only need to be done if you change the test leads of the
fuse. This feature is very useful when checking Wiring Continuity with long
wires. For example when measuring the continuity of the earth protective
wires in a house.
Don't forget to short the test leads together while auto-nulling them.
