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.
U1253B Quick Start Guide
Frequency Measurement
During AC/DC voltage or AC/DC current
measurements, you can measure the signal
frequency by pressing
Frequency Counter Measurement
1 Set the rotary switch to
2 Press
to select the frequency
counter (
) function. The default input
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.
