The 707Ex is an intrinsically safe loop calibrator for use in explosion endangered areas. The Fluke 707Ex is certified in accordance with the ATEX directive (Ex II 2 G Ex ia IIC T4) in Zones 1 and 2.
Large display and simple, quick-click push rotary button 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
1 μA resolution for mA source, simulate and measure
Push button with 25% steps for fast, easy linearity checks
0-100% "span check" for fast confirmation of zero and span
Selectable slow fast & step ramp to provide smooth outputs for valve slewing & loop functional tests
Internal loop supply, so you can power & read a transmitter at the same time without carrying a DMM
Measures Vdc 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
Resistance is connected in series with the loop supply for compatibility with HART communicators
