7.9.2.6Lwr S-nat Temp – P626

This value is used for temperature compensation if the measured supernatant temperature is below this value.

The lower temperature (P626) must always be less than the upper (P625). Valid entries are between –40 and +85°C (-40 to 185 deg F).

The default is -5°C (25 deg F)

Parameter values (metric)			Parameter values (imperial)
Default	Min	Max	Default	Min	Max
-5	-40	+85	25	-40	185

7.9.2.7SoS constant - P627

The speed of sound at 0oC (32 deg F) for a particular supernatant can be programmed in m/s (ft/s imperial).

Default (metric m/s)	Default (imperial ft/s)
1402.0	4599.7

7.9.2.8Bottom Blanking – P628

This parameter allows the user to program a region close to the bottom of the tank which is not used by the system for normal blanket level measurement.

This is useful if there are any fixed obstructions in front of the transducer close to the bottom of the tank which cannot be moved or otherwise avoided.

The default value is 0.0 metres / 0 foot

Parameter values (metric)			Parameter values (imperial)
Default	Min	Max	Default	Min	Max
0.000	0.000	9.999	0.00	0.00	33.00

7.9.2.9Level Offset – P629

This parameter is used to provide an offset to the normal displayed sludge blanket level (D800). The value may be entered as a positive or negative value to provide the required offset to the normal displayed sludge blanket level.

Default is 0.0.
Parameter values (metric)			Parameter values (imperial)
Default	Min	Max	Default	Min	Max
0.0	-0.99	0.99	0.0	-3.0	3.0
