Performing frequency measurements
Measuring frequency
– Five ranges: 120.000 mV, 1.20000 V, 12.0000 V, 120.000 V, 750.00 V — range is
based on the voltage level of the signal, not frequency
– Measurement method: Reciprocal counting technique
– Signal level: 10% of range to full scale input on all ranges
– Gate time: 0.1 s or 1 period of the input signal, whichever is longer
– Input protection: 750 V RMS on all ranges
1 Press .
2 Connect the red and black test leads to the input terminal as shown in
Figure 1-14.
3 Probe the test points and read the display. In auto-ranging mode, the
multimeter automatically selects the appropriate range and the measurement
is displayed.
