| Intrinsically safe loop calibrator (Model 707Ex) |
| Manufacturer: Fluke |
| |
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¢ç compatible resistance is connected in series with the loop supply for compatibility with HART communicators
