# 1. Lin/Log

Activating Lin/Log means that the calculation is performed in linear mode instead of logarithmic mode.

That is, all values are first converted from logarithmic mode to linear mode then the calculation is performed and then the result of the calculation is converted back to logarithmic mode.

Please note!

A negative linear result cannot be converted to log mode.

To resolve that the minus sign is removed before converting to log mode and then added to the result after conversion.

To make a calculation, do as follows:

Click on the **Calculate** button to perform the calculation.

The resulting file can now be visualized on the corresponding View tab.
