P802 Display Offset
The value of this parameter is added to the reading before it is displayed, in
Measurement Units (P104).
It does not affect the relay setpoints or the mA output, only the reading on
the display.
You could use this feature if for example you wanted to reference the
reading to sea level, where you would enter the distance between Empty
Level (P105) and sea level. If the empty level point is below sea level, then
enter a negative value.
P804 Display Conversion
The reading is multiplied by the value of this parameter before being
displayed. The default is 1.0, but if for example you wanted to display the
reading in yards, then set the Measurement Units (P104) to feet, and set
P804 to 3.
Failsafe
P808 Fail-safe Mode
By default, if a fail-safe condition occurs, then the display, relays and the
mA output are held at their last known values until a valid reading is
obtained.
If required, then you can change this so that the unit goes to high (100% of
span), or low (empty) as follows:
Option
Description
1 = Known (Default)
Remain at the last
kno
wn
value
2 = High
Will fail to the
high
value (100% of Span).
3= Low
Will fail to the
low
value (empty)
