Description
The CA310 is a dedicated process calibrator which is capable in performing a control loop check and inspection of devices. It has three times higher accuracy of ±0.015% rdg.* to source and measure mA and voltage. It can be used under HART or BRAIN communication with 250 ohm resistance embedded. *“rdg.” is an abbreviation of reading which means the error rate to the measurement value.
