5.2 Functions which require pressing several keys
:
5.2.1 Display shifting
Shifting of the display down scale (AdJ.Lo)
Shifting of the display full scale (AdJ.Hi)
After injecting an input signal corresponding to the down (or full) display
scale, press simultaneously and
(or and ) The message
AdJ.Lo (AdJ.Hi) will appear alternating with the value, to indicate that
you are in the menu adjustment.
The down (or full) display scale can be increased or decreased by
pressing and .
If you keep pressing or during 3 seconds you can increase or
decrease the display value quicker.
Press to validate the shifting. Once the shiftings have been validated,
the input will keep the same shifting even after a setting off tension.
Press (or do not press any key during 20 s) to revert to the measure
display without modification.
•
Case of a process, resistance or potentiometer input
The instrument will then re-adjust its scale factor and its display factor in
order to obtain the required result on the display.
•
Case of a temperature input
On a temperature input, if one of the two settings is performed this will
correspond to an offset, which means that all points will be shifted by the
same quantity.
But if the two settings are performed the slope and the offset will be cor-
rected in order to obtain the required result.
example
:
For a PT100 input for 0°C the obtained display is -000.3
For 500°C the obtained display is 0500.2. To correct this display, the
display down scale must be shifted by 3 points to obtain 000.0 and the
display full scale by -2 points to obtain 0500.0.
note
: only for
temperature inputs

From the menu rEAd, the performed scale shiftings can be visualised in
the submenu InPut:

5.2.2 Visualisation of the direct measure
Press and to visualise the signal directly without any processing:

for the Pt100, Ni100 input,
−

Suppressing of the input shifting:
(Case of a temperature input only)
The menu AdJuS. in the mode programming of a temperature input
allows to suppress the entered shifting, or not.
no:
the instrument will revert to the factory settings
Yes:
the instrument will take the programmed (offset and/or slope)
adjustments into account.
