f) Frequency measurement

The DMM can be used to measure the frequency of a signal volt-

age (supports frequencies from 10 Hz to 10 MHz). The maximum

input is 20 Vrms. This mode is not suitable for taking measure-

mentsonmainsvoltages.Observetheinputspecicationsinthe

technical data.

Proceed as follows to measure frequency:

- Switch the DMM on and select “Hz” mode. “Hz” will appear on

the display.

- Insert the red test lead into the Hz measurement socket (G)

and the black test lead into the COM measurement socket (H).

- Connect the two measuring probes to the object that you want

to measure (e.g. signal generator or circuit).

- The frequency and corresponding unit will be displayed.

- After taking a measurement, remove the leads from the meas-

ured object and switch the DMM off.

g) Measurement of pulse duration in %

The DMM can be used the ratio of the pulse duration of an alter-

nating voltage signal’s positive half wave as a percentage of the

entire period. The maximum input is 20 Vrms. This mode is not

suitable for taking measurements on mains voltages. Observe

theinputspecicationsinthetechnicaldata.

Proceed as follows to measure the pulse duration in %:

- Switch the DMM on and select the “Hz” measurement range.

“Hz” will appear on the display. Press the “SELECT” button (I)

on the rotary control. “%” will appear on the display.
