Brochure

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 Eex ia IIC T4) in Zones 1 and 2. The 707Ex is
also certified to operate in accordance with Factory
Mutual N.I. Class 1, Division 2 areas Group A-D.
●
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 ramp, fast ramp, and step ramp to provide
smooth outputs for valve slewing and loop functional tests.
●
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
®
compatible resistance is connected in series with the
loop supply for compatibility with HART communicators.
