Warning!
The AC voltage measurement has 4 measurement positions on the rotary switch: 2V, 20V,
200V and 750V.
To measure AC Voltage, connect the Meter as follows:
1. Insert the red test lead into the
terminal.
2. Set the rotary switch to an appropriate measurement position in
3. Connect the test leads across with the object being measured.
The measured value shows on the display, which is effective value of sine wave (mean value
response).
Note
• If the value of voltage to be measured is unknown, use the maximum measurement position
(750V) and reduce the range step by step until a satisfactory reading is obtained.
• The LCD displays "1" indicating the existing selected range is overloaded, it is required to
select a higher range in order to obtain a correct reading.
• When AC voltage measurement has been completed, disconnect the connection between
the testing leads and the circuit under test.
Warning!
Never attempt an in-circuit current measurement where the open circuit voltage between
terminals and ground is greater than 60V DC or 30V rms.
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 connected to the current terminals, do not parallel them across any circuit.
The DC current measurement has 4 measurement positions on the rotary switch: 2mA, 20mA,
200mA and 20A.
To measure current, do the following:
1. Turn off power to the circuit. Discharge all highvoltage capacitors.
2. Insert the red test lead into the mA or 20A terminal and the black test lead into the COM
terminal.
3. Set the rotary switch to an appropriate measurement position in 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
• If the value of current to be measured is unknown, use the maximum measurement position
(20A) and 20A terminal, and reduce the range step by step until a satisfactory reading is obtained.
• When current measurement has been completed, disconnect the connection between the
testing leads and the circuit under test.
