• Change between DC and AC when V, µA, mA or A are selected.
• Change between , Diodes test, Continuity test or Capacitance when rotary switch
are selected for any of this functions.
Voltage measurement DC and AC
(See fig 1)
1. Insert the red test lead into the HzV terminal and the black test lead into the COM terminal.
2. Set the rotary switch to V—for DC or V~ for AC. Low voltage value to mV and select Dc or
AC with blue button.
3. Connect the test leads across with the object being measured. The measured value shows on the
display.
4. Push Hz% for measure frequency or duty cycle.
Note
• Displays OL selected range is overload in manual ranging, it is required to select a higher range
in order to obtain a correct reading. Auto range, the instrument always select the best range for
input signals.
• In each range, the Meter has an input impedance of approx.10M . This loading effect can cause
measurement errors in high impedance circuits. If the circuit impedance is less than or equal to
10k , the error is negligible (0.1% or less).
Current measurement DC and AC (See fig 2).
Warning
Never attempt an in-circuit current measurement where the voltage between terminals and ground
is greater than 250 V.
If the fuse burns out during measurement, the Meter may be damaged or the operator himself may
be hurt. Use proper terminals, function, and range for the measurement.
When the testing leads are connect-ed to the current terminals, do not parallel them across any
circuit.
If the current is more than 5 Amp.Measuring time for current should be less than 10 sec and interval
time between measurement should be 15 minutes.
To measure current, connect as follows:
1. Turn off power to the circuit. Discharge all high-voltage capacitors.
2. Insert the red test lead into the 10 A or µAmA terminal and the black test lead into the COM
terminal.
3. Set the rotary switch to µA mA or A position.
4. Select DC or AC with blue button.
5. 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.
6. Push Hz% for measure frequency or duty cycle.
Note
• Displays OL selected range is overload in manual ranging, it is required to select a higher range
in order to obtain a correct reading. In Auto range the instrument always select the best range for
input signals.
Resistance measurement (See fig 1)
1. Insert the red test lead into the HzV terminal and the black test lead into the COM terminal.
2. Set the rotary switch to position (blue).
3. Push blue button to select resistance function. Display shows .
4. Connect the test leads across with the object being measured. The measured value shows on the
display.
