Q. I already own the ICN50B InstaCal module. Can I use it with the S331L?
A: No The ICN50B is not compatible with the S331L. The built-in InstaCal communicates with the S331L via the rear multi-pin connector. The ICN50B communicates with the E series Site Master through the center conductor of the test port.
