LogC1
Logarithmic representation for the following combination:

TTR connected to measurement channel 1

PTR connected to measurement channel 2
TTR + PTR
Table 43 – Chart recorder output – Calculation formula for the parameter LogC1
LogC2
Logarithmic representation for the following combination:

CTR or DU connected to measurement channel 1

CTR or DU connected to measurement channel 2
This output characteristic is only preferred when the sensors offer different measurement
ranges. The total measurement range supplied by the combination is displayed in the range
of 0 to 10 V logarithmically. This parameter can only be selected for GRAPHIX TWO and
THREE.
