Sensor Offset (2.2.5.); Blanking (2.2.6.) - Siemens HydroRanger 200 HMI Operating Instructions Manual

8.6.2.5

Sensor offset (2.2.5.)

Calibrates Empty (2.2.4.) (Page 170) if the reported level is consistently high or low by a
fixed amount.

Before using this feature, verify the following parameters are correct:
● Empty (2.2.4.) (Page 170)
● Process temperature (2.11.1.3.) (Page 218)
● Offset reading (2.12.6.) (Page 238) (if using OCM)
● Zero head (2.13.4.5.) (Page 244)
Offset calibration
Begin with a steady level.
1. Measure the actual reading (use tape measure).
2. Enter the measured value from Step 1 into this parameter.
The deviation between the entered Empty (2.2.4) (Page 170) value and the calibrated Empty
value is stored in Offset Correction (2.11.1.9.) (Page 221)
8.6.2.6

Blanking (2.2.6.)

The space near the transducer face which cannot be measured.

Use this feature if the surface is reported to be near the transducer face but is in fact much
further away. Extend this value when changing transducer location, mounting, or aiming.
