40MHz/400MRPM 10KHz/300KRPM IV rms 0.01% ±10 digits
Overload Protection: 600V rms
*Less than 20Hz the sensitivity is 1.5V
To Measure Frequency:
1. Plug the black test lead into the COM port and the red test
lead into the °C°F 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.

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.
