  • Page 9: Using The Log Scale Function

    Using the Log scale Function Log Scale Display Function You can apply a logarithmic voltage that has been converted from a physical value to the recorder, and then use the log scale (logarithmic scale) to display and record the physical value.

  • Page 10: Restrictions

    Using the Log scale Function Restrictions Partial You cannot set the partial display on a channel that is set to log scale. Differential Computation between Channels If you set the reference channel of a differential computation between channels to a channel that is set to log scale, an error will be returned as the measured result of the differential computation between channels.

    Setting the Log scale Setup Examples pseudo-Log input and Log input (nonlinear log) setup examples are shown below. Setting the Pseudo-Log Range This setting is for logging the pseudo log output (see the table below) of a vacuum gauge.

  • Page 22 Setting the Log scale Setting the Log input (Nonlinear Log) In this example, pressure is measured by applying calibration correction to linearly approximate the nonlinear output of a vacuum gauge. Calculating linearizer Input and linearizer output The following figure is an example of a nonlinear output of a vacuum gauge. The 10 red dots in the figure are the set points for the linearizer approximation.
