40MHz/400MRPM 10KHz/300KRPM IV rms 0.01% ±10 digits
To Measure Frequency:
1. Plug the black test lead into the COM port and the red test
lead into the VΩHz port.
2. Set the rotary switch to the HZ RPM position.
3. For RPM, Push the blue button until RPM is shown on
the display.
4. Connect the meter in parallel with the load or circuit.
5. Measure Frequency or RPM.
Overload Protection: 600V rms
*Less than 50Hz the sensitivity is 1.5V.

To Measure DC 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 the mA or A position.
3. Push the blue button until DC is shown on the display.
4. Connect the meter in series with the load or circuit.
5. Measure DC Current.
