a power interruption, the counter won’t advance. Therefore, a unit that is powered down
on a regular basis will not have an accurate value.
P342 Start Ups

Range Calibration (P650 to P654)
There are two types of calibration possible:
Offset: Adjusts the measurements by a fixed amount.
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.
