Additel'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.
