Additel’s ADT209 Loop Calibrator is the ideal instrument for troubleshooting process loops. The expansive display shows the measurement with the % of span concurrently. The ADT209 has the capacity for measurements of current, voltage and switch all with an accuracy of 0.03% of reading. Simulating or sourcing mA or a process transmitter can be easily accomplished as well. The loop calibrator allows for alternating between zero and span values, auto ramp, and auto step through the range with ease and efficiency. The Additel ADT209 is standard for applications that require the need to source, simulate or measure.
