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
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.
