Model CL309A is a state of the art,
highly reliable, rugged and easy-to-use
milliamp calibrator. It has the functions
necessary to perform all the required
maintenance and calibration tasks of
virtually any 4 to 20 mA loop. It provides
source and read milliamp functions
along with power, measure, and
2-wire transmitter simulations.
In addition, it can
measure DC Voltage
for troubleshooting
power supplies.
