To convert Setpoint LO to a second high setpoint, set software switch 3 of the configuration
menu to 1 (ConFIG = XX1XXX). LO ALARM becomes active when the reading is greater (more
positive) than that setpoint.
To convert both setpoints to latched setpoints, set software switch 2 of the configuration menu to
1 (ConFIG = X1XXXX). When relays are energized, they stay energized until a Reset (either
front-panel or back connector reset).
