6. Battery replacement
If the sign“BAT”appears on the LCD display, it indicates
that battery should be replaced. Remove the battery cover
of case. Replace the exhausted battery with a new one.
Warning
Before attempting to open the battery cover, be sure that
test leads have been disconnected from measurement
circuits to avoid electric shock hazard.

4. Specifications
Accuracy is specified for a period of one year after
calibration and at 18°C to 28°C (64°F to 82°F) with relative
humidity to 80%.
1. Connect the black test lead to the COM jack and the red
test lead to the V
Ω
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.
3.3 Measuring voltage
1. Connect the black test lead to the COM jack and the red
test lead to the V
Ω
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
overrange 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 V jack.
2. Set the rotary switch at desired 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 overrange 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.
Ω
Ω
3.6 Continuity test
1. Connect the black test lead to the COM jack and the red
test lead to the V
Ω
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 50
Ω
),
built -in buzzer will sound.
3.7 Measuring temperature
1. Set the rotary switch at °C or °F position and the LCD
display will show the current environment temperature.
2. Insert“ K ”type thermocouple into the temperature
measuring socket on the front panel and contact the
object to be measured with the thermocouple probe.
Read LCD display.
Warning
To avoid electric shock, be sure the thermocouple has been
removed before changing to another function measurement.
3.5 Testing diode
1. Connect the black test lead to the COM jack and the red
test lead to the V
Ω
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.

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
19M
Ω
, change clamp meter and insulation tester unit to
20M
Ω
range, can be increase 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.
