3.3 Measuring Frequency
The instrument will measure the frequency of the line voltage V
During frequency measurement, only the line voltage VRS
frequency is measured. Specifically, the instrument measures
the differential signal between voltage sensor R (1) and voltage
sensor S (2).
1
Display the Frequency
Measurement screen (p. 2 9).
2
Check the measured value.
(The frequency of the line voltage
VRS will be displayed.)
The display will indicate
frequency is less than 45.0 Hz or
frequency exceeds 66.0 Hz.
3
Press MODE.
(The Line Voltage Measurement
screen will be displayed.)
