WIRING TRILOOP

Configure Channels 1, 2, and 3 to reflect the units as well as Upper Range Values and Lower Range Values for your secondary, tertiary and fourth variables (variable assignment is configured in the Model 3300). It is also possible to enable or disable a channel from this menu. See “Special Functions“ on page 4-24for further information on how to install a Tri-Loop.
