Blind Setting Of Start Of Scale Value - Siemens SITRANS P DS III Operating Instructions Manual

Setting without reference pressure
Blind setting resets the start of scale value to the lower sensor limit and the full scale value to
the upper sensor limit.
Note
If the value exceeds or falls below the preset measuring limits by more than 20% when
setting, the setting function is not carried out. The old value is retained in this case.
With a marked elevation of the zero point, the full scale value must therefore previously be
reduced such that it still lies within the permitted range after elevation of the zero point.

Blind setting of start of scale value

Introduction
Blind setting resets the start of scale value to the lower sensor limit.
Note
Changes in modes 5 and 6 have an exclusive effect on pressure scaling. This does not
affect the scaling for level or customized characteristic curve. Therefore, only measured
pressure values and pressure units are displayed in these modes.
Condition
You are familiar with the correct operation of the transmitter and the associated safety notes.
You have not created any reference pressure and have selected a pressure unit.
Procedure
To the set the start of scale value blindly, proceed as follows:
1. Set mode 5.
2. Press the [↑] and [↓] buttons simultaneously for 2 seconds.
