Input Type
A highly accurate and powerful system for testing, measuring and calibrating built into a single compact portable instrument. The OMEGA™ CL427 indicator/simulator 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. 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.

Works well, needs better documentation
Worked well for our purposes, but the documentation for this was lacking. We did not realize that USB couples ground plane of CL427 to whatever it is plugged into. Additionally unit must be "on" to charge which we did not realize at first. Overall though it does what it advertises and is convenient.

I have two questions: Does Omega offer any type of Authorization Letter or Certificate for the consumer to be considered approved to use the CL427 for calibrations? Does Omega have cal procedures for IR and Type K contact thermometers?
As with other calibrators, Omega does not have a specific statement that authorizes the consumer to be considered approved to use the CL427; the customer will need to determine if it meets the needs of the entity they are certifying in accordance with. To use the CL427 for any unit that is being calibrated, please refer to the calibration instructions in sections 1 thru 4 of the operator's manual (link here): https://assets.omega.com/manuals/M5160.pdf

Can this display a 4-20 mA output value and at the same time display a measured 4-20 mA input value?
Thank you for your inquiry. This unit can only source or measure, not at the same time.

how is the CL427 setup to generate mV source voltage using the T/C/mV port for calibrating load cells?
Please select the mV range first. With this range selected connect leads to the T/CmV source terminals.
