1. SAFETY INFORMATION
The circuit under test must be de-energized and isolated before
connections are made except for voltage measurement.
Verify operation prior to measuring hazardous voltages (voltage
above 30V AC rms, 42V AC peak and 60V DC).
Do not touch the circuit connections during a test.
Disconnect the live test lead before disconnecting the neutral
test lead.
After insulation tests, to protect from electric shock, capacitive
circuits must to be discharged.

4. BEFORE OPERATION
Warning
To avoid electrical shock remove test leads before opening case or
battery cover. Do not operate with battery cover open.
To avoid electrical shock when performing resistance tests, remove
all power from the circuit to be measured.
To avoid electrical shock, first connect the test leads to the meter
inputs before you make connection to the circuit under test.
To avoid electrical shock, do not touch test lead tips, test points or
terminals when pressing TEST.
4-1 How to connect test leads.
Connect the red test lead into the “ VΩ” terminal and the black
lead into the “ COM ” terminal.
4-2 Battery Check & Replacement
1) If battery power is not sufficient, LCD will display “ BT ”.
Replacement of 6 pcs new batteries, type 1.5V size “AA” is required.
2) Use a screwdriver to unscrew the screw secured on battery cover.
Take out the used batteries and replace 6 pcs new batteries.
3) Replace the battery cover and secure the screw.
4-3 Test Leads Check
Set the range select switch to the HEATING CABLE range. Connect
the crocodile clips with the test lead tips, Clip alligator clips with
lead other. The indicator should read <0.5Ω. When the leads are
not connected the display will read infinity indicated by “ .”. This
will ensure that test leads are under working condition.

press “▼” key select “YES” or “NO”, then press “MEM” key to
exit this mode. To clean all of the memories, select “YES”.
2) Manual data memory
cPress "MEM" key each time, one set of reading will be stored
to the memory. At this moment, LCD will show the "MEM"
mark and the memory address number. Total memory size is
9 sets.
dWhen the memory is full, LCD will show " F " memory address
number.
3) Read Manual memory data
cPress "READ" key to enter READ mode, the LCD will show
"READ" mark and the memory address number.
dPress "▲" or " ▼" key to select the desired memory address
number data for display.
ePress " READ " key again to exit this mode.

5. VVOLTAGE MEASUREMENT
1) Set the function switch to V position.
2) Connect red test lead to “ VΩ” terminal and black test lead to
“ COM ” terminal.
3) Connect the probe IN PARALLEL to the circuit to be measured.
4) Read the voltage value from the display. The meter indicates AC
voltage on the main display.
6. FLOOR PROBE - RESISTANCE MEASUREMENT
1) Set the function switch to FLOOR PROBE position.
2) Connect red test lead to “ VΩ” terminal and black test lead to
“ COM ” terminal.
3) Connect the probe to floor probe wires.
4) Read the resistance value from the display.
7. HEATING CABLE <1000ΩRESISTANCE MEASUREMENT
1) Set the function switch to HEATING CABLE <1000Ωposition.
2) Connect red test lead to “ VΩ” terminal and black test lead to
“ COM ” terminal.
3) Zero out the test lead resistance (see section 3.5 Zero key).
4) Connect the probes to the cable wires (black & white / red).
5) Read the resistance value from the display, if the resistance is
<10Ω, the meter will beep.

8. MΩINSULATION RESISTANCE MEASUREMENTS
8-1 Measuring Insulation Resistance
Measuring insulation resistance requires the application of
potentially dangerous voltage to the circuit. This may include
exposed bonded metal work.
Before proceeding, ensure that the installation is correctly wired
and no personnel are endangered by any test.
1) Set the function switch to the desired MΩtest voltage position.
2) Connect red test lead to “ VΩ” terminal and black test lead to
“ COM ” terminal.
3) The display will show “-----” until the TEST button is pushed.
Press and hold the TEST key. The upper right display shows
the test voltage applied to the circuit under test. The main
display shows the resistance until a stable resistance reading is
displayed on the main display.
4) Keep the probes on the test points when releasing the TEST
key. The upper right display shows the measured resistance
reading and the main display show “- ---”, while the circuit now
discharges through the meter.
5) Verify that the circuit is completely discharged. Set the function
switch to the other MΩtest voltage position. The upper right
display shows the decreasing voltage, keep the probe touched
to test points until the circuit is completely discharged and the
display shows “0V”.
8-2 Using the LOCK Function to Measure Insulation Resistance
The LOCK function holds the test voltage on the probes. Use
LOCK function to make long duration measurements, don’t need
to push and hold the TEST key.
1) Press and hold down LOCK key then press TEST key enter to
LOCK mode. In this mode, a potentially dangerous voltage is
continuously applied to the probes.
10

In this mode, if the probes are disconnected from the circuit, the
meter cannot discharge any potentially dangerous capacitive
voltages left on the circuit.
Ensure that the circuit is de-energized before connecting the test
probes.
2) Press LOCK or TEST key to disable the Lock function.
9. BATTERY REPLACEMENT
1) Set the function switch to OFF position.
2) Disconnect test leads from any power source.
3) Place the meter face down on a nonabrasive surface and loosen
the two screws.
4) Take off the battery cover.
5) Remove the battery, replace with six new batteries.
6) Place the battery cover on and secure the two screws.
10. MAINTENANCE & CLEANING
1) Repairs or servicing not covered in this manual should only be
performed by qualified personnel.
2) Periodically wipe the case with a dry cloth.
Do not use abrasives or solvents on this instrument.
