Documenting calibrator

Beta Calibrators' MasterCAL 990 documenting calibrator provides precision calibration and HART functionality in a handheld instrument.

As a precision calibrator designed for field applications, the MasterCAL 990 reads thermocouple, RTD, ohms, DC and AC voltage, DC current, pressure, and frequency, and will source thermocouple, RTD, ohms, DC voltage and current, and frequency. Numerous functions make field use quick and easy, including loop power, switch test, a transmitter simulator mode, automated and user-programmable procedures. Measurements can be displayed in engineering units, percent of scale, square-law inputs, or custom units. A 200 x 240 pixel, bright white backlit LCD provides simultaneous split-screen input and output display. The MasterCAL 990 calibration automation and documentation is compatible with many popular third-party software packages.

As a Hart configurator/communicator, the MasterCAL 990 provides support for universal, common-practice, and device-specific commands for a variety of devices. The 990 supports point-to-point operation, as well as multi-drop and burst-mode operation. Hart configurations can be read and written, transmitter configurations can be read and cloned, smart transmitters can be re-tagged, and HART sensor and output trim can be automated. Most instrument maintenance functions can be accomplished using just the MasterCAL 990, without the need for a separate Hart communicator. Hook-up is simple with the supplied Hart interface cable. The calibrator menus automatically branch to appropriate adjustment choices. Automatic completion of test templates and automatic fetching and sending of analog readings during trim operations make Hart calibration highly efficient.
