3. OPERATING INSTRUCTION
3.1 MEASURING CURRENT
1. Set the rotary switch at desired A~ range position.
Press the trigger to open the transformer jaws and clamp
onto one conductor only (Fig.1), The transformer jaws pick
up the AC current flowing through the conductor.
2. When only the figure “1” displayed, it indicates overrange
situation and the higher range have to be selected.
WRONG CORRECT
Fig 1.
3.2 INSULATION TEST
(Option 500V insulation tester unit)
1. Connect the insulation tester unit VΩ, COM, EXT three-
banana plugs to the clamp meter VΩ, COM, EXT.
2. Set the rotary switch of clamp meter at 2000MΩ position.
3. Set the insulation tester unit range switch to the 2000MΩ
position.
4. Uses the insulation tester unit of the test leads connects
its L, E input connect to being tested installations.
(Test installation's must be power OFF)
5. Set the insulation tester power switch to the ON position.
6. Depress the PUSH 500V push-push switch; the 500V on
red LED lamp will light. Clamp meter display reading is the
insulation resistance value. If the reading is below 19MΩ
change clamp meter and insulation tester unit to 20MΩ
range, can be increasing the accuracy.
7. If the insulation tester unit is not use, the power switch
must shift to power OFF position, and the test leads must
leave the E. L input connect. That can be increase battery
life and prevent electrical shock hazard.
3.3 MEASURING VOLTAGE
1. Connect the black test lead to the COM jack and the red
test lead to the VΩ jack.
2. Set the rotary switch at the desired V or V~ range position
and connect test leads across the source or load under
measurement. The polarity of the red lead connection will
be indicated along with the voltage value when making DC
voltage measurement.
3. When only the figure“ 1 ”is displayed, it indicates over
range situation and the higher range has to be selected.
3.4 MEASURING RESISTANCE
1. Connect the black test lead to the COM jack and the red
test lead to the VΩ jack.
2. Set the rotary switch at desired Ω position and connect
test leads across the resistor under measurement.
NOTE:
1. If the resistance being measured exceeds the maximum
value of the range selected or the input is not connected, an
over range indication “1” will be displayed.
2. When checking in - circuit resistance, be sure the circuit
under test has all power removed and that all capacitors
have been discharged fully.
3.5 TESTING DIODE
1. Connect the black test lead to the COM jack and the red
test lead to the VΩ jack. (The polarity of red lead is “+”)
2. Set the rotary switch at position and connect red lead
to the anode, black lead to the cathode of the diode under
testing. The meter will show the approx. forward voltage of
the diode. If the lead connection is reversed, only figure “1”
displayed.
3.6 CONTINUITY TEST
1. Connect the black test lead to the COM jack and the
red test lead to the VΩ jack. (The polarity of the red lead is
positive“ + ”)
2. Set the rotary switch at position and connect test leads
across two points of the circuit under testing. If continuity
exists (i.e., resistance less than about 100Ω), built -in buzzer
will sound.
WARNING
To avoid electric shock, be sure the thermocouple has been
removed before changing to another function measurement.
3.8 MEASURING FREQUENCY
1. Connect the black test lead to the COM jack and the red
test lead to the VΩ jack.
2. Set the rotary switch at Hz position and connect test leads
across the source or load under measurement.
NOTE:
1. Reading is possible at input voltage above 10V rms, but
the accuracy is not guaranteed.
2. In noisy environment, it is preferable to use shield cable
for measuring small signal.
4. SPECIFICATIONS
Accuracy is specified for a period of one year after calibration
and at 18℃ to 28℃ ( 64℉ to 82℉) with relative humidity
to 80%.
