DRUCK UPS_iii回路校准器英文说明书.doc

GE Sensing Features The UPS III is a rugged and extremely compact loop calibrator. Measuring 3 in x 5 in (77 mm x 129 mm) and weighing just 9.7 oz (275 g), 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. ? Measure or source 0 to 24 mA ? Accuracy 0.01% of reading ? Dual mA and % readout, linear or flow ? Step, span check, valve check, ramp ? 60 VDC measurement and continuity ? Hart? compatible UPS III Druck Loop Calibrator UPS III is a Druck product. Druck has joined other GE high-technology sensing businesses under a new name—GE Sensing. g  GE Sensing Graphic Display Auto Step and Ramp Outputs have adjustable rates (1 to 599 s) for single-handed loop testing, valve set-up and slew rate checks. The graphic display with menu-driven interface is easier to use than traditional knobs, switches, multi-function keys and dual key sequences. “Fast Set” Output Measure or Source 0 to 24 mA Allows values to be set to within 0.001 mA using the arrow keys. Holding a key quickly ramps the output to the next value. The system is ideal for alarm trip tests. An internal 24 V loop supply is available in both measure and source modes, essential during plant shutdowns. Accuracy 0.01% of Reading 60 VDC Measurement 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). For loop diagnostics and maintenance of voltage output instruments. Continuity and Switch Test Facility Simultaneous % Readout This reduces DMM dependence when fault finding, checking loop integrity and testing switches. Displays mA and the percentage value of 4 to 20 mA or 0 to 20 mA. The UPS III also converts mA readings to % flow. This is not possible with many loop calibrators. Hart Compatible Internal 23
