Channel - LEYBOLD GRAPHIX ONE Instruction Manual

LogC4
Logarithmic representation over 12 decades (0.83 V/decade) for the following combination:

TTR100 or TTR101 connected to measurement channel 1

ITR200 connected to measurement channel 2
TTR100 + ITR200
TTR101 + ITR200
Table 59 – Chart recorder output – Calculation formula for the parameter LogC4
U = 10 V corresponds to p = 1000 mbar. The switchover level between the sensors is at 10

mbar. This parameter can only be selected for GRAPHIX TWO and THREE.
PM411
Non-linear output characteristic as for the PM411 plug-in board.
