Revision as of 15:38, 7 April 2019

Evaluation of background noise level for RPICT series version 2 & 3.

Only applies to RPICT8 / RPICT7V1 / RPICT4V3 / RPIZ_CT4V3T1 / RPI_LCT4V3 / RPI_LCT8.

Does NOT apply to RPICT3V1 / RPICT3T1 / RPICT4T4.

CT only - RMS Current

Channel open and sensor disconnected.
