The 707Ex is an intrinsically safe loop calibra-
tor 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. The 707Ex is also certified to operate
in accordance with Factory Mutual N.I. Class 1,
Division 2 areas Group A-D. The 707Ex features:
•
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.
•
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.
•
Innovative output adjustment dial with
.001 mA and 0.1 mA resolution.
•
HART
®
compatible resistance is connected in
series with the loop supply for compatibility
with HART communicators.
