Parameters when S5=6/7 (resistance based sensor)
1)
The decimal point in the measuring range must be observed!

Trimming of measuring range
The measuring range, and consequently the measured value itself, can be corrected to
compensate for sensor tolerances to calibrate the instrument for use with other indica-
tors.
CA1 - for trimming at the lower end of the measuring range
CE1 - for trimming at the upper end of the measuring range
PC1 The PC1 resets the trimming performed using CA1/CE1.

Definition of measuring range
Method 1: resistance values are known
Select MA1 and ME1 parameters and enter known resistance values:
CA1 and CE1 parameters are ignored.
Method 2: resistance value unknown
Calibrate start of scale
value
• Set control element to 0% and select CA1 parameter;
• Press button (9) until 0.0 is displayed;
Calibrate full scale value
• Set control element to 100% and select CE1 parameter;
• Press button (9) until 100.0 is displayed;
Line resistance is then trimmed automatically; parameters MA1/ME1 are ignored.
