Portable calibrator

30 March 2011 Test & Measurement

Comtest Technologies has introduced the Fluke 5522A multiproduct calibrator which is designed to improve the capabilities of calibration laboratories across all industries. The instrument aims to provide daily service both inside and outside of the calibration lab because it is durable enough to be safely transported for on-site or mobile calibration of a wide variety of electronic test tools.

The 5522A is suitable for metrology engineers, technicians and lab managers who need to calibrate many different types of electronic equipment and require a transportable instrument that delivers a high return on capital investment. For a single calibrator, the device gives the flexibility to calibrate a wide range of instruments and can be fully automated with MET/CAL Plus calibration management software. Several reliability enhancing features protect it against damage and make it easier to transport for on-site or mobile calibration. Internal circuits and fuses protect against damage caused by applying too much voltage or current.

The broad array of electronic test tools which can be calibrated includes handheld and bench meters (analog and digital) up to six digits; current clamps and clamp meters; thermocouple and RTD thermometers; process calibrators; dataloggers; strip and chart recorders; Wattmeters; power harmonics analysers; panel meters; graphical multimeters; power quality analysers (with option); analog or digital oscilloscopes to 600 MHz or 1,1 GHz (with options); pressure gauges and transducers; and three-phase power meters.

Front and rear access doors are removable and the 5522A can be used while its top, bottom and side panels remain protected — all without having to completely unpack and re-pack the calibrator. A redesigned front panel and carrying handles make it easy to transport the calibrator short distances within the lab. The instrument provides reverse power protection, immediate output disconnection and/or fuse protection on the output terminals for all functions.

The 5522A sources direct voltage and current, alternating voltage and current with multiple waveforms and harmonics, two simultaneous voltage outputs or voltage and current to simulate DC and AC power with phase control, resistance, capacitance, thermocouples and RTDs. It can also measure thermocouple temperature signals and a wide range of pressures using any of 29 Fluke 700 series pressure modules.
