SQRT - allows presenting on the display the squared root of the linear input
signal. The Cut-Off parameter given in % of the input signal makes input values
below (Lim Low + Cut Off) be shown as Lim Low. See figure 16.

DEC.PT - sets the decimal point to exhibit the engineering units on the upper
display. Up to three decimal places may be set for linear processes whereas
temperature sensors may have one or no decimal place.
OFSET - allows the user to enter an off-set value in Engineering Units to be
added to the measured variable. This parameter can be used to equalize
measurements in different instruments.
CJC - cold junction compensation for thermocouples. Select INT for internal
cold junction compensation; otherwise, select NO. Generally INT should be selected.
Input sensor types are described in table - 1 of section 1.3 on Technical
Specifications.
FILTER - this parameter provides the time constant of a first order digital filter
associated to the selected input. In order to leave the signal without filter set this
parameter to zero.
