Range Calibration (P650 to P654)
There are two types of calibration possible:
Offset:
Sound Velocity: Adjusts speed of sound and changes the measurement calculations.
Do Offset calibration at any steady level unless a Sound Velocity calibration is also done.
If both calibrations are done then do Offset at a known high level and Sound Velocity at a
known low level.
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)
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).
