during measurement is conducted to prevent damage of the Meter.
• When the Meter working at an effective voltage over 60V in DC or 42V rms in AC, special care should be
taken for there is danger of electric shock.
• Do not use or store the Meter in an environment of high temperature; humidity, explosive, inflammable and
strong magnetic fields. The performance of the Meter may deteriorate after dampened.
• When using the test leads, keep your fingers behind the finger guards.
• Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity,
diodes and current.
• Before measuring current, check the Meter fuses and turn off power to circuit before connecting the Meter
to the circuit.
• Replace the battery as soon as the battery indicator appears. Whit to low battery, the Meter might produce
false readings that can lead to electric shock and personal injury.

Power
• On/Off switch. Automatic off after 15 minutes.
Hold
• Hold function. H shows on the display when value is hold.
Voltage measurement DC and AC
(Fig 1)
1. Insert the red test lead into the VΩHzºC terminal and the black test lead into the COM terminal.
2. Set the rotary switch to an appropriate measurement position in V--range for DC or V~ for AC. When the
value is unknown always start from the max range 1000 V.
3. Connect the test leads across with the object being measured.The measured value shows on the display.
Note
• Displays 1 selected range is overload; it is required to select a higher range in order to obtain a correct
reading.
• In each range, the Meter has an input impedance of approx.10MΩ. This loading effect can cause
measurement errors in high impedance circuits. If the circuit impedance is less than or equal to 10kΩ, the
error is negligible.
Current measurement DC and AC
(Fig 2).
Warning
Never attempt an in-circuit current measurement where the voltage is greater than 250 V. If the fuse burns
out during measurement, the Meter may be damaged or the operator himself may be hurt. When the testing
leads are connected to the current terminals, do not parallel them across any circuit.
Measuring time for current over 10A should be less than 10 sec and interval between measurement should be
at least 15 minutes.
1. Turn off power to the circuit. Discharge all high-voltage capacitors.
2. Insert the red test lead into the A or mA terminal and the black test lead into the COM terminal.
3. Set the rotary switch to an appropriate measurement position A-- range for DC or A~ for AC. When the
value is unknown always start from the max range 20 A.
4. Break the current path to be tested. Connect the red test lead to the more positive side of the break and the
black test lead to the more negative side of the break.
5. Turn on power to the circuit. The measured value shows on the display.
Note
• Displays 1 selected range is overload, it is required to select a higher range in order to obtain a correct
reading.
Resistance measurement
(Fig 1)
1. Insert the red test lead into the VΩHzºC terminal and the black test lead into the COM terminal.
2. Set the rotary switch to an appropriate measurement position in Ω range.
3. Connect the test leads across with the object being measured. The measured value shows on the display.
