LR Linear
The output voltage is linear and
proportional to the measured leak rate.
The increase is set with the “Analog
scale” setting (see below).
LR log.
The output voltage displays the leak rate
logarithmically. The corresponding values
are set with the “Analog scale” setting
(see below).
Current lin
The output voltage displays the current
linearly. The upper limit value is set with
the “Analog scale” setting (see below).
Current log.
The output voltage displays the current
logarithmically. The corresponding values
are set with the “Analog scale” setting
(see below).
Scaling
You can set the scaling of the analog output.
► In the main menu, select “Settings > Interfaces > Analog output scaling”.
Set the final value and the increase (volt/decade) for outputs 1.. 2 and 3 ... 4
separately.
The upper limit applies for the “LR linear”, “LR log.”, “Current lin” and “Current log.”
settings.
The increase (volt/decade) applies for the “LR log.”, and “Current log.” settings.
