the lower display is showing its value, this key allows
to store the selected value for the current parameter
and access the next parameter within the same group.
Allows to increase the value of the selected parameter.
Allows to decrease the value of the selected parameter.

These two keys allow to return to the previous
group. Proceed as follows:
Push the
button and maintaining the pressure,
then push the
button; release both the buttons.
Note:
The group selection is cyclic as well as the selection
of the parameters in a group.
5.6 FACTORY RESET - DEFAULT
PARAMETERS LOADING PROCEDURE
Sometime, e.g. when you re-confi gure an instrument
previously used for other works or from other people or when
you have made too many errors during confi guration and
you decided to re-confi gure the instrument, it is possible to
restore the factory confi guration.
This action allows to put the instrument in a defi ned
condition (the same it was at the fi rst power ON).
The default data are those typical values loaded in the
instrument prior to ship it from factory.
To load the factory default parameter set, proceed as follows:
1.
Press the
button for more than 5 seconds. The upper
display will show
PASS
while the lower display shows
0
;
2.
Using
and
buttons set the value -481;
3.
Push
button;
4.
The instrument will turn OFF all LEDs for a few seconds,
then the upper display will show
dFLt
(default) and then
all LEDs are turned ON for 2 seconds. At this point the
instrument restarts as for a new power ON.
The procedure is complete.
Note:
The complete list of the default parameters is available
in Appendix A.
5.7 CONFIGURING ALL THE PARAMETERS
In the following pages we will describe all the parameters of
the instrument. However, the instrument will only show the
parameters applicable to its hardware options in accordance
with the specifi c instrument confi guration (i.e. setting
AL1t
[Alarm 1 type] to
nonE
[not used], all parameters related to
alarm 1 will be skipped).

Notes: 1.
When a TC input is selected and a decimal fi gure

displayed value becomes 999.9°C or 999.9°F.
2.
Every change of the SEnS parameter will
produces a change of the related parameter and
in particular:
• [7] bS (PV bias) will be forced to zero
• [11] Ao1L and [12] Ao1H (when the analog
retransmission is present) will be forced to the
Ex.Range limits.
• [13] AL1 and [30] AL2 will be forced to :
–
for an absolute maximum alarm, them will be
forced to the maximum input span
–
for an absolute minimum alarm, them will be
forced to the minimum input span
–
for all other alarm, them will be forced to zero
• [14] HAL1 and [31] HAL2 will be forced equal
to the 0.5% of the input span
• [28] AL2L extended limit low
• [29] AL2H extended limit high
• [35] HYS will be forced equal to 0.05 % of the
input span
• [37] SPLL and [38] SPHL

[2] dP - Decimal point position
Available:
Always.
Range:
0 to 3 when [1] SenS = Linear input;
0 or 1 when [1] SenS different from linear input.
Note:
Every change of the dP parameter setting will produce
a change of the parameters related with it (e.g.: set
points, proportional band, etc.).
[3] SSc - Initial scale read-out for linear inputs
Available:
When a linear input is selected by [1] SenS.
Range:
-1999 to 9999.
Notes: 1.
SSc allows the scaling of the analog input to set
the minimum displayed/measured value.
The instrument will show a measured value up to
5% less than SSc value and then it will show an
underrange error.
2.
It is possible to set a initial scale read-out higher
than the full scale read-out in order to obtain a
reverse read-out scaling.
E.g.:
0 mA = 0 mBar and 20 mA = -1000 mBar (vacuum).
[4] FSc - Full scale read-out for linear input
Available:
When a linear input is selected by [1] SenS.
Range:
-1999 to 9999.
Notes: 1.
Fsc allows the scaling of the analog input to set
the maximum displayed/measured value.
The instrument will show a measured value up to
5% higher than [4] FSc value and then it will show
