This loop calibrator is designed with output current, Simulate output current, output voltage function,
it is used for detecting and debugging automatic control equipment in industry scene.
Features
• Measures V dc to 28 V.
• 0 - 20 mA or 4 - 20 mA default start up modes.
• Push button 25% steps for fast, easy linearity checks.
• 1 µA resolution for mA source, simulate and measure.
• 0-100% “span check” for fast confirmation of zero and span.
• HART ™ mode connects 250 Ω resistor in series with 24 V loop for compatibility with HART communicators.
• 24 volt internal loop supply, so you can power and read a transmitter at the same time without carrying a DMM.
•Selectable slow ramp, fast ramp, and step ramp to provide smooth outputs for valve slewing and loop
• Innovative output adjustment dial with 1 µA and 100 resolution.
• Single 9V battery that is easily changed without braking calibration seal
• Simultaneous mA and % readout for quick, easy interpretation of readings.
• mA accuracy of 0.025%, superior to other loop calibrators in this price range.
• Large display and simple, quick-click interface for easy one-handed operation functional tests.
