2.4 Frequency & Period Measurements
DL-2060 uses an on-board counter with 25MHz to measure the frequency (period). The
measurement band is from 3Hz to 300kHz (or 333 ms to 3.3
μ
s) and the measurement
voltages range from 100mV to 750 V in AC. The default for “RANGE” is auto-range.
Warning! The maximum input allowed is 1000V
(peak). Applying excess voltage
may damage your meter.
How to measure frequency and period
①
Selects input signal connections on front or rear panel.
②
Connect the test leads to the terminals as shown in
Figure 3-2
.
③
Set RESOLUTION (Refer to 3.1.1) and INPUT JACK. Or skip this step if default is to be
used.
④
Press FREQ button for frequency measurement or SHIFT + PERIOD(FREQ) buttons
for period measurement.
⑤
Select the auto-range function by pressing AUTO button on the front panel or use
△
and
▽
buttons to select the desired range.
⑥
Connect test leads to your source signal and observe the reading shown on the
display. If the input signal is beyond the allowed range, an overflow message “OVLD”
will be displayed.
※
Note: The rear terminal panel can
also be used via the same procedures as the front
panel. (Please refer to
Figure 3-3
