tina96e1-b (2016-12) VGC501_VGC502_VGC503.om 71
This parameter combines different pressure ranges to one combined pressure
range, if several linear gauges with different full scales (F.S.) are connected to the
VGC502 and VGC503. Thus the pressure for this combined pressure range can be
read out with best accuracy.
The pressure is higher than the full scale of the gauge with lower full scale: The
VGC502/503 switches to the gauge with higher full scale.
Only one linear gauge is connected: The measurement value of this gauge is out-
put.
No linear gauge is connected: 1000 mbar is output as measurement value and the
parameters a, b and c are set to "0".
Channel 1: linear gauge, 1000 mbar F.S.
Channel 2: linear gauge, 10 mbar F.S.
