Making Measurements
Measuring Frequency and Period 4
4-7
The available impedance settings are presented in sets of three
values. To move to a higher set of impedance values, press ++
-->. Press <-- -- to go to a lower set of impedance values.
3. With the impedance highlighted, press the soft key under the
value selected.
2ND MEAS Cycles the secondary display through the measurement functions
listed below, and then off. When a second measurement function is
selected, the 2ND MEAS soft key label is highlighted.
VDC - Displays the dc voltage on which the ac signal may be riding.
Note
ACV/DCV dual mode should not be used at frequencies
below 10 Hz.
Frequency - Displays the frequency of the ac signal applied to the
Input HI and LO connectors of the Meter.
Measuring Frequency and Period
The Meter measures the frequency, or period of ac signals between 3 Hz and 1 MHz,
applied between the Meter’s HI and LO connectors.
The G key not only activates the Meter’s Frequency/Period function, but also toggles
the Meter’s primary display between the signal’s frequency and period measurement.
Therefore, whether a frequency or period measurement appears after pressing G
depends on the condition this function was left in the last time it was used.
To make a frequency measurement:
1. Press G.

If S is displayed, press G again to switch the primary display to frequency.
2. Connect the Meter to the signal as shown in Figure 4-1.
To make a period measurement:
1. Press G.
If HZ is displayed, press G again to switch the primary display to period.
2. Connect the Meter to the signal as shown in Figure 4-1.
Note
Each press of G switches the measurement between frequency and
period.
