MEASURING FREQUENCY (see figure 13)
• Press Hz button to select frequency measurement mode at m
frequency measurement mode and return to the previous measurement mode.
• The maximum range of frequency is 1 MHz.
• The signal attenuation is different from different measuring position and range.
Therefore the required signal input amplitude and range may be different from different measuring
position and range.
• It is recommended to use the
• If the input amplitude is higher than 1Vrms, it is required to use
measurement.
• When using current range to measure frequency, it is required to input signal more than 30 % of
full range. The reading obtained is only for reference.
Note:
• When Frequency measurement has been completed, disconnect the connection between
the testing leads and the circuit under test, and remove the testing leads away from the input
terminals of the Meter.
