P650 Offset Calibration
Calibrates Empty (P006) if the reported level is consistently high or low by a fixed amount.
Before using this feature, verify the following parameters are correct:
• Empty (P006)
• Temperature (P664)
• Offset Reading (P062)
• Zero Head Offset (P605), if using OCM
Offset Calibration
Begin with a steady level.
1. Press TRANSDUCER to display the calculated reading.
2. Repeat Step One at least five times to verify repeatability.
3. Measure the actual reading (use tape measure).
4. Enter the actual value.
The deviation between the entered Empty (P006) value and the calibrated Empty value is
stored in Offset Correction (P652).
P651 Sound Velocity Calibration
Changes the speed of sound constant.
Condition for use of this feature
• The acoustic beam atmosphere is other than air
• The acoustic beam atmosphere temperature is unknown
• The Reading accuracy is acceptable at higher material levels only
For best results, calibrate with the level at a known value near empty.
