Testing and Measuring Operations
Frequency Measurement
Hz FRQ CTR
– Frequency Counter mode is used for mea-
suring the frequency of an alternating voltage signal.
Contact the probe tip to the circuit and it will display the
frequency in Hertz (cycles per second) in the main display
area while also displaying the – Pulse Width and + Pulse
Width in milliseconds on the bottom line.
The Power Probe IV can measure frequencies from 1Hz to
9999Hz.
FRQ CTR can be used for tests where frequency or pulse
width are needed such as MAF sensors, wheel sensors,
etc.
