ADT209/210 Loop Calibrator

ADT209 Additel Loop CalibratorAdditel's newest loop calibrators the ADT209 and ADT210 combine ease of use and functionality, making them the ideal tools to troubleshoot your process loop.

The ADT209 has an accuracy of 0.03% of reading whereas the ADT210 holds an accuracy of 0.01% of reading. If you want to source, simulate or simply measure this Additel Loop calibrator series will fit your need. The ADT209 and ADT210 allow for measurement of current, voltage and a switch. You can also simulate or source mA or a process transmitter. With a push of a button, you can switch to zero and span values, auto ramp, and auto step throughout the range.

Each loop calibrator has a large, easy to read screen which simultaneously displays the measurement with the % of span.

Applications: 

The ADT209 and ADT210 allow for measurement of current, voltage and a switch. You can also simulate or source mA or a process transmitter. With a push of a button, you can switch to zero and span values, auto ramp, and auto step throughout the range.
