Fluke 707 Loop Calibrator

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 0.015%, superior to other loop calibrators in this price range.
1µA 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 9 V battery that is easily changed.
0-20 mA or 4-20 mA default start up modes.
Innovative output adjustment dial with 1 µA and 100 µA resolution.
HART™ mode connects 250 W resistor in series with 24 V loop for compatibility with HART communicators.
