7.8.1 Setting the starting value of scaling (Sc.Lo)
Setting range: 0 to 75% of the nominal measuring range
Factory setting: Initial value of measuring range
Example The instrument has a nominal measuring range -400 ... +400 mbar
The output signal of the instrument is 0 ...20 mA
Objective: The range from 0 to 200 mbar (customer's measuring
range) will be represented on the output side by
0...20mA.
Setting: The initial value of scaling (Sc.Lo) = 0.000
The final value of scaling (Sc.Hi) = 200.0
Result: At a pressure of less than 0 mbar the instrument reports
an error (value below lower measuring range limit) and
makes the corresponding error signal (0 mA) available at
the output.
At a pressure of 0 mbar the instrument makes 0 mA
available at the output.
At a pressure of +200 mbar the instrument makes 20 mA
available at the output.
At a pressure greater than +200 mbar the instrument
reports an error (measuring range exceeded) and makes
the corresponding error signal (22 mA) available at the
output.
Setting ✱ Unlock the instrument, See section 7.2 "Unlocking the instrument (code
entry)", page 27.
✱ "Rotate" until the bottom line shows "Sc.Lo".
✱ "Press"
The output signal can only be scaled for instruments with
analog output!
Enter the value "digit by digit."
