Keyboard functions during the parameter modification
A short pression on the button allows to exit the current parameter group and select the next one. A long pression allows to close the configuration parameter procedure (the instrument returns to the “Standard display”).
When the display is showing a group the button allows to enter the selected group. When the display is showing
a parameter, this button allows to store the selected value and to go to the next parameter within the same group.
Increases the value of the selected parameter.
Decreases the value of the selected parameter.
+ These buttons allow to return to the previous group.
Proceed as follows:
Push the button and maintaining the pressure push the button. At this point, release both the buttons.
Note: The group selection is cyclic as well as the selection of the parameters in a group.

Factory reset - Default parameters loading procedure
Sometimes, 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 instruent in a defined condition (the condition it was at first Power ON).
The default data are those typical values loaded in the instrument before being shipped from factory.
To load the factory default parameter set, proceed as follows:
1. Press the button for more than 5 seconds;
2. The display shows alternately PASS and 0;
3. By and buttons set the value -481;
4. Push button;
5. The instrument will turn OFF all LEDs for some seconds, then it will show dfLt (default) and turns ON all
the LEDs 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 parameter is available in Appendix A.

All parameters configuration
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] equal to nonE [not used], all parameters related with the 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. Any modification to the SEnS parameter setting will force the following changes:
[3] dP 0;
[4] SSc -1999;
[5] Fsc 9999.
[3] dP - Decimal point position
Available: Always.
Range: When [2] SenS = Linear input: 0... 3.
When [2] SenS ≠ linear input: 0 or 1 Note: Any modification to the dP parameter setting will produce a change to the parameters related with it (e.g.:
set points, proportional band, etc.).
