To Measure Voltage:
1. Plug the Black test lead into the COM port and the Red test lead into the VHz port.
2. Set the rotary switch to either the V or mV position.
3. Push the blue button to choose between DC, AC, or AC+DC measurements.
4. Connect the meter in parallel with the load or circuit.
5. Measure the voltage
6. The AC and AC+DC measurements provide a True RMS measurement.
7. For AC Measurements, the frequency of the measured signal > 20% of full scale is displayed on the sec-
ondary display.

Voltage Burden: 800mV max. for mA input; 1V max. for A input.
Input Protection: Equipped with high energy fuse.
1A, 600V, IR 10kV fuse for mA input
15A, 600V, IR 100kV fuse for A input.
AC Conversion Type: AC Coupled, True RMS responding
AC+DC Volts: Same as ACVRMS +1.00% + 8 digits
Crest Factor: +1.5% addition error for C.F. from 1.4 ~ 3
+3.0% addition error for C.F. from 3 ~ 4
To Measure Current:
1. Plug the Black test lead into the COM port and the Red test lead into the mA or A port.
2. Set the rotary switch to either the mA or A position.
3. Push the blue button to choose between DC, AC, or AC+DC measurements.
4. Connect the meter in series with the load or circuit.
5. Measure the current.
6. The AC and AC+DC measurements provide a True RMS measurement.
7. For AC Measurements, the frequency and period of the measured signal are displayed on the secondary
displays.

Warning
Limit large current measurements (10~20A to 30 seconds,
and allow two minutes of cooling between readings.
Do not connect to circuits with >600V.
