2.5 Frequency & Period Measurements
DL-1060 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
μs) and the
measurement voltages range from 100mV to 750 V in AC. The range default setting is
auto-range.
The maximum input allowed is 750V. Applying excess voltage may
damage your meter.
How to measure frequency
1.
Connect the test leads to the terminals on the front panel as shown in
