Additel 209 and 210 Series Loop Calibrator
OVERVIEW
The new Additel 209 and 210 loop calibrator series 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, the 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.
