Setup Setpoint
Set “Channel” to the required conductivity input
channel and “Trigger” to USP.
This causes the setpoint to operate to the USP levels
stated. It will also force the selected channel’s units to
“Siemens”, the cell constant to “0.01” the display
range to “9.999μS” and Temperature Compensation
to “Out”
Note. The rest of the menus for this setpoint will be
disabled.

USP Pre-Trigger
In addition any other setpoint assigned to the same
channel as the USP setpoint can be configured as a
pre-trigger and will cause the setpoint to activate by
the pre-trigger amount before the USP level.
Example. If the USP setpoint 1 was due to activate at
1.300μS/cm and the pre-trigger setpoint 2 was set to
0.200μS/cm then setpoint 2 would trigger at
1.100μS/cm.
