Plugging 30A probe to measure up to 30A current.
Measuring Frequency
The meter measures the frequency of a voltage or current
signal by counting the number of times the signal crosses a threshold level each
second.
This function only can be operated in AC voltage and current measurements. The
ranges of measuring frequency are 400Hz, 4kHz, 40kHz and 100kHz.
If a reading shows as 0 Hz or is unstable, the input signal may be below or near the
trigger level. The detail of frequency trigger level refer to the electrical specifications.
To use the frequency function, press MODE in the AC measurements, and press Hz
key, once activated, will change color, and pressing it again will deactivate the function.
Make High Frequency Rejection Measurement (HFR)
WARNING
• Do not use the High Frequency Rejection (Low Pass Filter) option to verify the
presence of hazardous voltages. Voltages greater than what is indicated may be
present. First, make a voltage measurement without the filter to detect the possible
presence of hazardous voltage. Then select the filter function.
