CONFIGURATION PARAMETERS
P1 - Input type and standard range
0 = TC type L range 0 / +800 °C
1 = TC type J range 0 / +800 °C
2 = TC type K range 0 / +999 °C
3 = TC type N range 0 / +999 °C
4 = RTD type Pt 100 range -199 / +500 °C
5 = RTD type Pt 100 range -19.9 /+99.9 °C
6 = TCtype T range 0 / +400 °C
8 = TC type L range 0 / +999 °F
9 = TC type J range 0 / +999 °F
10 = TC type K range 0 / +999 °F
11 = TC type N range 0 / +999 °F
12 = RTD type Pt 100 range -199 / +999 °F
13 = TC type T range 0 / +752 °F
NOTE : setting a readout with °F as engineering
unit it is necessary to put on the front of the
instrument, the additional label located in the
“INDEX” of this manual.
P2 = Initial scale value
Not present when P1 = 5
Insert the initial and full scale values which are
going to be used by the PID algorithm to calculate
the input span.
P3 = Full scale value
Not present when P1 = 5
Insert the initial and full scale values which are
going to be used by the PID algorithm to calculate
the input span.
NOTES :
1) the minimum input span (P3 - P2) is 300 °C or
600 °F for TC input and 100 °C or 200 °F for
RTD input.
2) Changing P2 and/or P3 parameters, the rL and
rH parameters will be realligned to it.
3) If, during configuration procedure, a °C range
has been selected, it is necessary to put the °C
label on the front of the instrument covering the °F
indication. The sticker is located with the gasket in
the shipping box.
4) Re-insert the instrument.
6) Power the instrument “ON”.
The display will show CnF.
NOTE : If “CAL” indication is displayed, press
immediately the
s
pushbutton to return to
the configuration procedure.
7) Push the FUNC pushbutton.
The parameter code and its value are shown
alternately on the display.
Puscbutton functionality during
configuration procedure.
FUNC = Must be pressed to store the new value
of a selected parameter and incre-
ments to the next parameter.
SMART = in configuration mode, scrolls
parameters back (in reverse order)
without storing the new parameter
value.
s
= increases the value of the selected
parameter
t
= decreases the value of the selected
parameter.
