Features

ATEX Intrinsic Safe Certification for use in classified areas.
Large display and simple, quick-click push rotary button for easy one-hand operation.
Simultaneous mA and % readout for quick, easy, interpretation of readings.
mA accuracy of 0.015%, superior to other loop calibrators.
1µA resolution for mA source, simulate and measure.
Push button with 25% steps for fast, easy linearity checks.
0 to 100% "span check" for fast conformation 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 separate DMM.
Measures volts DC to 28 volts.
Single 9 volt battery that is easily changed.
Innovative output adjustment dial with 1µA and 100µA resolution.
HART® compatible resistance is connected in series with the loop supply for compatibility with HART communicators.
