Features of Loop Calibrator
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.
mA accuracy of 0.025%, superior to other loop calibrators in this price range.
Simultaneous mA and % readout for quick, easy interpretation of readings.
1 µA resolution for mA source, simulate and measure.
Selectable slow ramp, fast ramp, and step ramp to provide smooth outputs for valve slewing and loop functional tests.
0-100% ‘span check’ for fast confirmation of zero and span.
24 volt internal loop supply, so you can power and read a transmitter at the same time without carrying a DMM.
HART ™ mode connects 250 Ω resistor in series with 24 V loop for compatibility with HART communicators.
Measures V dc to 28 V.
Single 9V battery that is easily changed without braking calibration seal
Push button 25% steps for fast, easy linearity checks.
0 - 20 mA or 4 - 20 mA default start up modes.
Innovative output adjustment dial with 1 µA and 100 resolution.
