H717 Accuracy 0.025% Loop Calibrator with Li Battery

Product Description

Accuracy 0.025% Loop Calibrator YHS-717

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 µ A 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 µ A and 100 resolution.
* HART Mode connects 250 Ω Resistor in series with 24 V loop for compatibility with HART communicators.
