SAFETY INFORMATION
zRead the following safety information carefully before attempting to operate or service the meter.
zTo avoid damages to the instrument do not apply the signals which exceed the maximum limits shown in
the technical specifications tables.
zDo not use the meter or test leads if they look damaged. Use extreme caution when working around bare
conductors or bus bars.
zAccidental contact with the conductor could result in electric shock.
zUse the meter only as specified in this manual; otherwise, the protection provided by the meter may be
impaired.
zRead the operating instructions before use and follow all safety Information.
zCaution when working with voltages above 60V DC or 30V AC RMS. Such voltages pose a shock
hazard.
zBefore taking resistance measurements or testing acoustic continuity, disconnect circuit from main
power supply and all loads from the circuit.
Safety symbols:
Caution refer to this manual before using the meter.
Dangerous voltages.
Meter is protected throughout by double insulation or reinforced insulation.
When servicing, use only specified replacement parts.

2-1 How to connect test leads.
On MΩRange , and 400Ω/BZ ,ACV,.DCV, Connect the red test lead into the “VΩ” terminal and the black
lead into the “COM” terminal.
2-2 Battery Check-UP & Replacement
a) As battery power is not sufficient. LCD will display . Replacement of 6 pcs new batteries, type 1.5V
size “AA” is Required.
b). Place back the battery cover and four the screws.
2-3 Test leads check
Set the range select switch to the 400Ωrange. With the tip and alligator clip of the test leads connected. The
indicator should read 00.0Ω. When the leads are not connected the display will read infinity indicated by
“OL”. This will ensure that test lead are under working condition.
2-4 Rotary Switch positions
Turn the Tester on by selecting any measurement

6.BATTERY SAVER (SLEEP MODE)
The meter will automatically enter the “sleep mode” if there is no function change or button press for
10minutes, but it works as soon as you turn the rotary function switch or push down any button.
7.POWER TOOLS AND AMALL APPLIANCES
This test would also apply to other similar equipment that has a line cord. For double insulated power tools,
the megohmmeter lead shown connected to the housing would be connected to some metal part lf the
tool(e..g chuck,blade).
Note: The switch of the device must be in the “ON” position and the main power should be disconnected.
MOTORS
AC-Disconnect the motor from the line by disconnecting the wires at the motor terminals or by opening the
main switch. If the main switch is used and the motor also has a starter then the starter must be held, by
some means, in the “ON” position. In the latter case, the measured resistance will include the resistance of
the motor, wire and all other components between the motor and the main switch. If a weakness is in
dicated, the motor and other components should be checked individually. If the motor is disconnected at the
motor terminals, connect one megohmmeter lead to the grounded motor housing and the other lead to One
of the motor leads. DC-Disconnect the motor from the line. To test the brush rigging, field coils and armature
connect one megohmmeter lead to the grounded motor housing and the other lead to the brush on the
commutator. If the resistance measurement indicates a weakness, raise the brushes off the commutator and
separately test the armature, field coils and brush rigging by connecting one megohmmeter lead to each of
them individually, leaving the other connected to the grounded motor housing. The above also applies to DC
Gemerators.
CABLES
Disconnect the cable from the line. Also disconnect opposite end to avoid errors due to leakage from other
equipment. Check each conductor to ground and /or lead sheath by connecting one megohmmeter lead to a
ground and /or lead sheather and the other megohmmeter lead to each of the conductors in turn. Check
insulation resistance between conductors by connecting megohmmeter leads to conductors in pairs.

NOTE: "This instrument doesn’t have ATEX protection, so it should not be used in potentially explosive
atmospheres (powder, flammable gases)."
