Introduction
WARNING
Safety Information
This Insulation Tester is an accurate, professional industry tool
for measuring ACV, DCV, Frequency, Earth-Bond -Resistance,
Insulation Resistance.
Understand and follow operating instructions carefully.
• If the equipment is used in a manner not specied by the
manufacturer, the protection provided by the equipment may
be impaired.
• Always use proper terminals, switch position, and range for
measurements.
• To reduce the risk of re or electric shock, do not use this
product around explosive gas or in damp locations.
• Verify the Meter operation by measuring a known voltage.
If in doubt, have the Meter serviced.
• Do not apply more than the rated voltage, as marked on
Meter, between terminals or between any terminal and earth
ground.
• To avoid false readings that can lead to electric shock and
injury, replace battery as soon as low battery indicator blinks /
appears.
• Avoid working alone so that assistance can be rendered.
• Do not use the Tester if the Tester is not operating properly or
if it is wet.
• Individual protective device must be used if hazardous live
parts in the installation where the measurement is to be
carried out could be accessible.
• Disconnect the test leads from the test points before changing
the position of the function rotary switch.
• Never connect a source of voltage when the function rotary
switch is not in voltage position.

603 EN

• When using test leads or probes, keep your ngers behind
the nger guards.
• Use caution with voltages above 30Vac rms, 42 Vac peak, or
60Vdc. These voltages pose a shock hazard.
• Remove test lead from Meter before opening the battery door
or Meter case.
• DO NOT USE the test leads when the internal white insulation
layer is exposed.
• DO NOT USE the test leads above maximum ratings of CAT.
Environment, voltage and current, that are indicated on the
probe and the probe tip guard cap.
• DO NOT USE the test leads without the probe tip guard cap
in CAT III and CAT IV environments.
• Probe assemblies to be used for MAINS measurements shall
be RATED as appropriate for MEASUREMENT CATEGORY
III OR IV according to IEC 61010-031 and shall have a
voltage RATING of at least the voltage of the circuit to be
measured.
• Only replace the blown fuse with the proper rating as
specied in this manual.
• Do not attempt a resistance measurement when the open
voltage is above the fuse protection rating. Suspected open
voltage can be checked with voltage function.
• Never attempt a voltage measurement with the test lead
inserted into the Ω input terminal.
• Disconnect circuit power and discharge all high-voltage
capacitors before testing resistance, continuity, or
capacitance.

Cleaning
To alert you to the presence of a potentially hazardous voltage,
when the Tester detects a voltage ≧30 V in insulation test, or
a voltage overload (OL), the ” “ symbol is displayed and High
voltage indicator is turned on.
Do not attempt to repair this Meter. It contains no user service
able parts. Repair or servicing should only be performed by
qualied personnel.
Periodically wipe the case with a dry cloth and detergent. Do
not use abrasives or solvents.

1. Before starting the test :
(a) The circuit under test must be completely de-energized.
(b) Check the fuse is good. See the chapter “ Testing the
fuse ”.
(c) Short the test leads before measurement, and press the
Function button to zero the wire resistance of probe. If
the wire resistance is <10Ω, the resistance o󰀨set value
will be saved, and the “->0<-” symbol will be displayed
on LCD.

1. Before starting the test :
The circuit under test must be completely de-energized.
If the voltage detected is above 30V, ">30V" will appear on
the display. In this condition, the test is inhibited.
2. Press the Function button to display insulation resistance or
Leakage current during the test or when the test stops.
3. Lock mode: Press the Lock button to enter the Lock Mode.
Then press TEST button >1sec to start the test. The test
voltage will continue to be applied until the TEST/LOCK
button is pressed again.
4. Stop the output test voltage before removing the test leads
(to enable the tester to discharge capacitive circuits).
If the screen displays volts, wait until it reaches zero.
5. The meter displays the " ＞" symbol and the maximum
resistance for the range when measured resistance is
higher than the maximum display range.
Before starting the Insulation Resistance test, select the
comparative value in Setup mode: 0.5MΩ, 10MΩ, 20MΩ,
50MΩ, 100MΩ, 200MΩ, 500MΩ, 1000MΩ.
