Model 707Ex Loop Calibrator |
| |
| The fast
one-handed tool for mA loop checks in Ex zones . |
|
|
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.

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.
- 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 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.
- HART® compatible resistance is connected
in series with the loop supply for compatibility with HART
communicators.
