for Electronic Device
A highly accurate and powerful
system for testing, measuring
and calibrating built into a single
compact portable instrument.
The OMEGA® CL427 indicatorsimulator is a multifunction
instrument designed to meet,
in a modern and practical way,
the needs of instrumentation
engineers, both in laboratory and
field work. Accurate, compact,
rugged and easy to use, it is
the ideal solution for measuring
and simulating: millivolts, volts,
milliamperes, frequency, sine,
square and triangular waveforms,
and thermocouples.
The CL427 has been developed
using the most advanced
microprocessor technology
to provide high accuracy on
extended ranges and a powerful
operating flexibility.
A unique internal automatic RJ
compensation system allows the
CL427 to provide accurate input
and output readings in operating
conditions with a temperature
range of 0 to 50°C (32 to 122°F).
Further, external compensation
is available that allows users to
fine tune temperature output and
measurement.
K-1
The model CL427 has been
designed for use in industrial
environments such as factory floors,
process plants, service departments
and maintenance workshops.
Millivolts, Volts, milliamps, and
frequency can be measured
or generated. Both accuracy
performance and stability allow
you to calibrate field and control
room instrumentation. Square
wave pulses can be generated with
frequencies from 0.3 Hz to 20 kHz.
Pulse height is adjustable between
100 mV and 20 Volts. With this
powerful function, the user can even
test electro mechanical devices
such as counters and relays.
Simulating non-linearized
temperature transmitters (Tx)
allows the user to check and
calibrate 4 to 20 mA system input
hardware and software quickly and
easily. User can set or manipulate
temperatures in °C or °F related to
any available sensor and send the
appropriate milliamps to the system
input. Milliamps can be monitored
simultaneously on calibrator display.
