LoG
Logarithmic representation of the entire measuring
range.
LoG A
Logarithmic representation of the entire measuring range
(compatible with VGC012, VGC023, VGC032).
LoG -6
Logarithmic representation of a part of the measurement
range (2.5 V/decade).
LoG -3
Logarithmic representation of a part of the measurement
range (2.5 V/decade).
LoG +0
Logarithmic representation of a part of the measurement
range (2.5 V/decade).
LoG +3
Logarithmic representation of a part of the measurement
range (2.5 V/decade).
LoGC1
Logarithmic representation matched to the following sen-
sor combination:
• PSG on channel 1
• PEG on channel 2
LoGC2
Logarithmic representation matched to the following sen-
sor combination:
• CDG on channel 1
• CDG on channel 2
This characteristic curve is only useful if the sensors have
different measuring ranges. The total measuring range of
the sensor combination is represented logarithmically in
the range 0…10 V.
LoGC3
Logarithmic representation matched to the following sen-
sor combination:
• CDG on channel 1
• CDG on channel 2
• CDG on channel 3
This characteristic curve is only useful if the sensors have
different measuring ranges. The total measuring range of
the sensor combination is represented logarithmically in
the range 0…10 V.
NOTE:
The three sensors must be sorted with regard to their
measuring range (FS). The sort order may be increas-
ing or decreasing.
Lin n
Linear representation. U = 10 V is equivalent of p = 10
n
mbar. The exponent n may be any integer value in the
range -10…+3.
