 JH-20B-type multi-channel signal calibrator can simulate all kinds of industrial process instrumentation sensors and transmitters, which can lose 11 road standard signal, multi signal calibrator can measure the number of instruments produced by the process variety of signals, so multiple signal calibrator for a new generation of automatic instruments, automatic control system debugging and verification. Because JH-20B multi signal calibrator with 24VDC output for the two-wire instrument for measurement purposes, it uses the JH-20B-type multi-calibrator signal after the matched no other instruments can be easily and accurately to more than one instrument at the same time on debugging and testing of.
