ATEX Intrinsic Safe Certification for use in classified areas. 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 Innovative output adjustment dial with 1µA and 100 µA resolution HART® compatible resistance is connected in series with the loop supply for compatibility with HART communicators

A large display and simple, pushbutton interface for ease of use. Simultaneous mA and % readout for quick, easy interpretation of readings. mA accuracy of 0.02% Push button 25% steps for fast, easy linearity checks. Save time over traditional knob type controls. "Span Check" for fast confirmation of zero and span. Selectable slow ramp, fast ramp, and step to provide smooth outputs for valve slewing and loop functional tests. 24 volt internal loop supply, so you can power and read a transmitter at the same time without carrying a DMM. Single 9V battery that is easily changed. 0 - 20 mA or 4 - 20 mA default start up modes.
