Chauvin Arnoux CA1631 [P01654402] Voltage/Current Process Calibrator, 0 to 24mA. The Chauvin Arnoux CA1631 Voltage/Current Process Calibrator is a process-signal calibrator that can be used for calibrating instruments that measure current or voltage. It produces a DC current loop of between 0 and 24mA as well as DC voltage between 0 to 20V whilst the measurement method is also possible with this calibrator. High accuracy (±0.02% + 3) means that calibration is very reliable and the option between current/voltage generation and measurement gives the user greater flexibility on site. The straightforward push-button interface on the Chauvin Arnoux CA1631 is very easy to use and information is provided to the user on the clear digital screen. The calibrator is powered by six AAA batteries and is light and portable, thus allowing calibration on site. This not only saves time but is also more accurate because testers are calibrated in real-world conditions. Futhermore, it is possible to power the instrument through the mains for extended periods of use. The Chauvin Arnoux CA1631 benefits from a 12-month manufacturer’s warranty and comes supplied with test leads, crocodile clips and a carry case.
