MS7207 Volt/mA High Accuracy Digital Loop Calibrator Process Calibrator
Features
The fast, one-handed tool for loop checks. Just click to calibrate.
This feature-rich solution combines the best features push-button and knob-base loop calibrator and offers:
· Large display and simple, quick-click interface for easy one-handed operation.
· Simultaneous mA and % readout for quick, easy interpretation of readings.
· mA accuracy of 0.025%, superior to other loop calibrators in this price range.
· 1 µA 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 ramp, fast ramp, and step ramp to provide smooth outputs for valve slewing and loop functional 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.
· Single 9V battery that is easily changed without braking calibration seal
· 0 - 20 mA or 4 - 20 mA default start up modes.
· Innovative output adjustment dial with 1 µA and 100 resolution.
· HART ™ mode connects 250 Ω resistor in series with 24 V loop for compatibility with HART communicators.
