1. GENERAL
This pulse checker is designed for inspecting, adjusting and maintaining a wide variety of equipment
associated with pulse signals. It features two groups of functions - the input functions which include the
accumulation, frequency measurement, period measurement and gated accumulation of input pulses and
the output functions which include the digital selection of the reference frequency, frequency reduction
and output frequency programming by selecting % frequency reduction, the control of the number of
output pulses, as well as the selection of pulse width and generator type.
Despite these elaborate capabilities, this portable pulse checker is easy to use.
To derive maximum bene
fi
t from the instrument, we recommend that you familiarize yourself with the
instructions contained in this manual.
