The UPS-III is a rugged and extremely compact loop calibrator. Measuring 77 mm x 129 mm(3 in. x 5 in.) and weighing just 275 g (9.7 oz), it fits comfortably in a shirt pocket. It is an essential tool for loop testing, instrument maintenance and valve set-up, with an easy to read display and simple to use time saving features. Features • Measure or source 0 to 24 mA • Accuracy 0.01% of reading • Dual mA or % readout, linear or flow • Step, span check, valve check, ramp • 60 VDC measurement and continuity • HART® compatible • Adjustable display contrast • Adjustable resolution • Uses industry standard AA batteries • Battery voltage and battery low indicator • Information screen reports serial number, software version and calibration date • Primary reading in mA or % Auto power off (enable or disable) • Pin protected closed case calibration • Optional protective over-boot with bench stand, hanging loop and quick connect belt clip • Optional AC line adaptor Graphic Display The graphic display with menu-driven interface is easier to use than traditional knobs, switches, multi-function keys and dual key sequences. Measure or Source 0 to 24 mA An internal 24 V loop supply is available in both measure and source modes, essential during plant shutdowns Accuracy 0.01% of Reading This includes 12 month stability and temperature effects. The UPS-III can maintain a 4:1 calibration ratio with the latest instrumentation and is typically 20 to 80 times more accurate than a Digital Multi-Meter (DMM) Simultaneous % Readout Displays mA and the percentage value of 4 to 20 mA or 0 to 20 mA.
