Most loop problems come down to a few questions: is the transmitter putting out the right current, is the loop powered, and does the controller read what it receives? The Additel 210 answers them with one small, rugged handheld that measures, sources, or simulates 0 to 24 mA and measures DC voltage to 30 V.

The 210 holds 0.01% of reading accuracy and shows the mA value together with the % of span on a large, easy to read display. Zero and span, auto ramp, and auto step are one button away, the 24 V loop power includes a HART 250Ω resistor in series, and the switch function checks trip points. One 9 V battery runs up to 50 hours in measure mode, and every unit ships with ISO 17025 accredited calibration with data and a 3 year warranty.
