9-4.
Setting up SC202 for USP
First enable USP in service code 57. Change the setting from 0 (default) to 1 (enabled).
This activates uncompensated conductivity in the display menu. The E13 feature is also enabled. For
E13 the FAIL flag is triggered when the uncompensated conductivity exceeds the relevant value in the
graph.
