5.6 CR10X with Multiplexer Sample Program

This program uses the CR10X and an AM16/32-series multiplexer to read 32
CS10-L current transformers.

;{CR10X}
; Example program for CS10-L
;
; Program to test the CS10-L or CS15-L sensor on a CR10X datalogger
; and AM1632 Multiplexer.

; This part of the program will calculate the RMS Amperage
; Standard Deviation in this part of the code works mathematically the same
; as RMS calculation, and it is easier to program this way. The RMS
; value is calculated and stored back into an input location for further
; processing if needed.
