Selecting an Input (INIt>INPt)
The Benchtop Digital Controller features a Universal Input. The input type is selected in the
Initialization Menu. Select the input type by navigating to the Input sub-menu (
INIt>INPt
).
Available Input types are shown in

Set the Setpoint 1 Value (PRoG > SP1)
Setpoint 1 is the main setpoint used for control and is displayed on the front of the unit. The unit will try
to maintain the input value at the setpoint using the selected outputs.
In the program menu, using the return button, select the
SP1
parameter. Use left
and right
buttons to set the process goal value for
PID
and
oN.oF
control modes.

Section 4.5
Section 4.6
for more information on setting up control modes.
