all coefficients in this group
should not be changed unless you are instructed by a
certified Aanderaa representative.
TempCoef
is calculated after a temperature calibration
performed at the factory.
C1R1Coef, C1R2Coef, C1R3Coef
and
C1R4Coef
is
calculated after calibration at factory for each of the four
ranges.
C2R1Coef
is only for factory use and therefor
write protected.
TSSCoef
are used to convert the sensor reading to

The last submenu in the

and holds settings
for:
TXReference Interval
; this is a sample interval divisor
for use of
TXReference
. When the value is set to
1
(default) the
TXReference
measurement is performed
during each sample. The value can be increased to
reduce power drain or to set a faster sampling interval,
less than
2 sec
. When the value is set to e.g.
10
, the
TXReference
measurement is only performed for each
10
th
sample.
