Measuring

This chapter describes the steps that are required to perform measurements
with the product.
Particular probes must be plugged in or switched on and registered (radio
probes) according to the variable that is to be measured.
Some probes require a warming-up phase until they are ready to measure.
For some variables additional calculation parameters have to be set if correct
measurements are to be obtained.
