Frequency/Period Measurement

The GDM-8352 can be used to measure the frequency or period of a
signal. This function can measure either the voltage
frequency/period or current frequency/period, depending on
which jack the input signal is input from.

Range

Frequency

10Hz~1MHz

Period

1.0

μ

s ~100ms

Procedure

To measure frequency, press the Hz/P key
once. The frequency will be displayed on the
primary screen and the range will be displayed
on the secondary display.
To measure the period, press the Hz/P key
twice. The period will be displayed on the
primary screen and the range will be displayed
on the secondary display.
