The Meter measures the frequency of a signal by counting
the number of times the signal crosses a trigger level each
second. The trigger level is 0 V, 0 A for all ranges.
Press g to turn the frequency measurement function
on and off. Frequency works with ac functions only.
In frequency, the bar graph and range annunciator indicate
the ac voltage or current present.
Select progressively lower ranges using manual ranging
for a stable reading.
