Frequency and Frequency Counter
Measurements
• Use the frequency counter for low voltage applications.
WA RN ING
Never use the frequency counter on AC power line
systems.
• For input more than 30 Vpp, you are required to use
frequency measurement mode available under the
current or voltage measurement instead of frequency
counter.

Frequency Measurement
During AC/DC voltage or AC/DC current
measurements, you can measure the signal
frequency by pressing

counter (
signal frequency is divided by 1. This
allows signals up to a maximum frequency
of 985 kHz to be measured.
3 Connect the red and black test leads to
input terminals V (red) and COM (black)
respectively.
4 Probe the test points and read the display.
5 If the reading is unstable or zero, press
to select division of input signal
frequency by 100 (
the display). This accommodates a higher
frequency range of up to 20 MHz.
6 The signal is out of the U1253B frequency
measurement range of 20 MHz if the
reading is still unstable after
at any time.
