Using the Log scale Function

Restrictions

2
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.
Computation Channels (/MT option)
Do not include channels that are set to log scale in a computation channel expression.
If you include these channels, an error will be returned as the measured result.
Report Function (/MT option)
You cannot create reports for channels that are set to log scale. An error will be returned as
the result of report computations on channels that are set to log scale.
Manual Sampled Data
For channels that are set to log scale, the data is stored using the "mantissa + exponent"
format, the same format as that of digital values on the recorder.
Number of Channels Set to Log Scale
Keep the number of channels set to log scale no greater than 300.
When there are many channels set to log scale, log scale processing may not finish within
the scan interval and may cause computation data dropouts.
