AO-MODE LOG C3 I  Logarithmic representation matched to the
following sensor 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.
The three sensors must be sor-
ted with regard to their measur-
ing range (FS). The sort order
may be increasing or decreasing.
AO-MODE LIN -10 I  Linear representation:
U = 10 V is equivalent of p = 10
-10
mbar
p = U/10 × 10
-10
…
Adjustable in the range LIN -10 … LIN +3
AO-MODE LIN +3 I  Linear representation:
U = 10 V is equivalent of p = 10
+3
mbar
p = U/10 × 10
+3
AO-MODE IM221 I  Logarithmic representation of the IM221
controller (1 V/decade):
U = 8 V is equivalent of p = 10
-2
mbar
p = 10^[U - 10]
AO-MODE LOG C4 I  Logarithmic representation of 12 decades
(0.83 V/decade) matched the following sen-
sor combination:
• PCG on channel 1
• BPG402 on channel 2
p = 10^[U/(10/12) - 9]
U = 10 V is equivalent of p = 1000 mbar.
The switching point between the sensors is
10
-2
mbar.

as with the PM411 board.
AO-MODE CH x I  Output voltage = input voltage
AO-MODUS PRM10K I  Nonlinear characteristic curve of the output
as with the PRM10K gauge from Edwards.
AO-MODUS IMR110 I  Logarithmic representation compatible with
IMR110 gauge, p = 10^[U/2 - 6]
AO-MODUS IMR120 I  Logarithmic representation compatible with
IMR120 gauge, p = 10^[U/2 - 8]
AO-MODUS IMR310 I  Logarithmic representation compatible with
IMR310 gauge, p = 10^[U*6/10 - 6]
AO-MODUS IMR320 I  Logarithmic representation compatible with
IMR320 gauge, p = 10^[U*7/10 - 9]
