HART Mode Digital Loop Process Calibrator - YH7007

Multifunction Digital Process Calibrator with HART Mode:

• The fas one-handed tool for current loop calibration, repair, maintenance
• This feature-rich solution combines the best features push-button and knob-base loop calibrator
• Large display and simple, quick-click interface
• Simultaneous mA and % readout for quick, easy interpretation of readings
• mA accuracy of 0.025%
• 1µA resolution for mA Source,Simulate and Measure
• Push button 25% steps for fast, easy linearity checks
• 0-100% “span check” for fast confirmation of zero and span.
• Selectable slow,fast ramp, and step ramp to provide smooth outputs for valve slewing and loop tests
• 24 volt internal loop supply, so you can power and read a transmitter at the same time without carrying a DMM
• Measures V DC to 28 V
• 0 ~20 mA or 4 ~ 20 mA default start up modes
