5.5 Factory reset - default parameters
loading procedure
Sometime, e.g. when you re-configure an instrument
previously used for other works or from other people or when
you have made too many errors during configuration and
you decided to re-configure the instrument, it is possible to
restore the factory configuration.
This action allows to put the instrument in a defined
condition (the same it was at the first 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.
5.6 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 specific instrument configuration (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 figure
is programmed (see the next parameter) the max.
displayed value becomes 999.9°C or 999.9°F.
2.
Every change of the SEnS parameter setting forces
[2] dP = 0 and it changes all parameters related
with dP (e.g. Set Points, proportional band, etc.).
[2] dP - Decimal point position
Available:
Always.
Range: 0... 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... 9999
.
Notes: 1.
SSc allows the scaling of the analogue input to
set the minimum displayed/measured value.
The instrument is able to display the measured
value until it reaches a value of 5% lower than SSc,
below which shows the Underrange message.
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... 9999
.
Notes: 1.
Fsc allows the scaling of the analogue input to set
the maximum displayed/measured value.
The instrument is able to display the measured
value until it reaches a value of 5% higher than
FSc, above which shows the Overrange message.
2.
It is possible to set a full scale read-out lower
than the initial scale read-out in order to obtain a
reverse read-out scaling.
E.g.:
0 mA = 0 mBar and 20 mA = -1000 mBar (vacuum).
