P861 Cal.Dist 1
When Ultra Wizard = 1 Level/Volume
This parameter can be used to re-calibrate the Sound Velocity (P860),
when the acoustic beam from the transducer is travelling through mediums
other than air or when there are variations of temperature between the
transducer face and the material level.
To obtain best results calibration should be carried out when the level is as
near empty as possible and when any vapour present has stabilized.
With the material at a steady level, view the value of P861, which will
indicate the current distance as calculated by Ultra 3 with respect to the
current value of P860. Physically measure the distance from the face of the
transducer to the surface of the material level and enter this value, in
Measurement Units P104 and P860 will be automatically updated to
compensate for any difference between the displayed and entered values.

Damping
Damping is used to damp the display, to enable it to keep up with the
process but ignore minor surface fluctuations.
P870 Fill Damping
This parameter determines the maximum rate at which the unit will
respond to an increase in level. It should be set slightly higher than the
maximum vessel fill rate. Default = 32.8084 feet/min
P871 Empty Damping
This parameter determines the maximum rate at which the unit will
respond to a decrease in level. It should be set slightly higher than the
maximum vessel empty rate. Default = 32.8084 feet/min
Indicator
P872 Fill Indicator
This parameter determines the rate at which the LCD fill indicator activates.
Default = 32.8084 feet/min
P873 Empty Indicator
This parameter determines the rate at which the LCD empty indicator
activates. Default = 32.8084 feet/min
