YH7007 Loop Calibrator 250ohms Hart Equivalent to Fluke-707 Loop Calibrator
YH7007 Loop Calibrator with 0.025% Accuracy And 250ohms Hart
Selectable slow ramp, fast ramp, and step ramp to provide smooth outputs for valve slewing and loop functional tests.
Loop Calibrator YH7007
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.
