CL535, $1050,
shown actual size.

The Omega CL535 is an excellent
tool for calibration, test, and
diagnostics of instruments that
use frequency signals. Instruments
include tachometers, frequency
counters, integrators, and any other
frequency devices in the shop, plant
and/or field. The CL535 brings all
the features you would expect
from a frequency calibrator and
timesaving new ones with the easy
dial knob and easy check switch,
saving hours of troubleshooting
time. The CL535 comes with an
LED indicator showing gate time
for easy trigger level adjustment.
When calibrating a totalizer, the
CL535 eliminates the need of a
stop watch. The calibrator will
automatically stop when the
selected number of pulses has
been sent to the totalizer.
