DISPLAY CONFIGURATION
Display Programming
The second menu corresponds to display configuration. This, in turn, consists of some submenus according to
previously programmed input type: through frontal keys configuration (SCAL or uSEr), through real input signal
(tEAC), calibrated range (CAL) and reading stabilization filter (FiLt).

PONDERATED AVERAGE FILTER "FiLt"
Sets low-pass filter cutoff frequency (Fc) which allows the instrument to smooth out undesirable display reading
fluctuations.
Display scaling
Display scaling is necessary when adapting display reading to a particular engineering unit. Display range can be
configured between -9999 and 9999 for JR-P (14mm-high digits) or between -1999 and 9999 for JR20-P
(20mm-high digits).
Display scaling is a linear process that consists in introducing two input values, referred as Input 1 and Input 2,
and their respective display values, referred as Display 1 and Display 2. On the basis of this proportional
relationship internal software calculates display value that would correspond to a given input value. Decimal point
position would complete required engineering units indication.
It is possible to scale display in an increasing or decreasing proportional mode depending on whether if second
display value (DISP.2) is greater or less than the first (DISP.1). In an increasing mode, display value increases
proportionally to the input value whereas in a decreasing mode, display value decreases. The left figure below
shows both scaling modes.

TRHOUGH FRONTAL KEYS CONFIGURATION "SCAL"
Input and display values are configured manually through
the three keys of the instrument. This method is suitable
when signal values supplied by the transducer at each
extreme point of the process are known.
REAL INPUT SIGNAL CONFIGURATION "tEAC"
Input values are directly introduced from CN2 input
connector just at the moment of signal capturing at
each point of the process. Display values are configured
FiLt
manually through the three keys, as in the previous case.
This method is suitable when signal values at each point are
unknown but, it is possible to lead process to the conditions
defined by these extreme points.

IMPORTANT IN "tEAC" MODE:
To ensure the best accuracy, both points 1 and 2
should represent extreme process limits.
