Detail: 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 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 A and 100 resolution.
# HART mode connects 250 resistor in series with 24 V loop for compatibility with HART communicators.
