Input protection: Maximum 250V DC or AC RMS.
METHOD OF MEASUREMENT
AC and DC Voltage Measurement
1. Scroll the rotary switch to , press “FUNC.” button, select DC voltage or AC voltage
measurement.
2. Connect the probe in parallel to the circuit or power supply to be measured.
3. Read the measuring value from the display. When measuring DC voltage, the display also
shows the voltage polarity of the red probe test point.
Warning
Do not input voltage higher than 600V, it’s possible to display higher voltage, but there may
be risk of damaging the instrument.
When measuring high voltage, be careful to avoid electric shock.
After completing all the measuring operation, make sure to disconnect the probe from the
measured circuit.
AC and DC Current Measurement
1. Turn the rotary switch to or , press “FUNC.” button, select DC current or AC current
measurement.
2. Shut off the power supply of the circuit under test. Discharge all the high voltage capacitors
on the circuit under test.
3. Disconnect the circuit to be measured. Connect the instrument to the circuit to be measured
in series.
4. Connect to the power of the circuit, and then read the measuring result from the display. If it
displays “OL”, it means the input exceeds the measuring range of the instrument. When
measuring the DC and AC, it will show the voltage polarity of red probe test point on the
display as well.
5. Shut off the power of the circuit under test. Remove the probe of the instrument and restore
the circuit.
Warning
To prevent possible electric shock, fire or personal injury, when measuring the current,
