Open circuit voltage: 3.3V
Open circuit low voltage: 0.6V
Input protection: 600V rms
To Measure Resistance:
1. Turn the power off to the circuit or device that is to be measured and discharge all capacitors before
attempting a measurement.
2. Plug the Black test lead into the COM port and the Red test lead into the VHz port.
3. Set the rotary switch to the LV position.
4. Press the blue button to choose between and LV.
LV setting reduces the maximum test voltage level to about 0.5V to avoid turning on semiconductor devices.

Sensitivity: 0.5Vp-p for 15Hz ~ 1MHz
1Vp-p for 1 MHz ~ 4MHz
Min. frequency: 5Hz
Input protection: 600V rms
To Measure Frequency:
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 the Hz %DF position.
3. For duty factor, push the blue button until % is shown on the main display, and Hz is shown in the upper
right secondary display.
4. Connect the meter in parallel with the load or circuit.
5. Measure frequency or duty factor.
Duty factor is the percentage of the signal that is high
