12 Advanced Measuring Functions
12.7.3 Output Options for a Calculation Channel
Make sure that the physical quantity selected for the calculation channel can be calculat-
ed from the physical quantities of the selected measuring channels. The possible combi-
nations are shown in Table 12.2.
Three scroll lists are displayed in the upper line:
• selection of the first measuring channel (CH1)
• selection of the calculation function (FUNCT)
• selection of the second measuring channel (CH2)
Select a scroll list with key or .
The list items will be displayed in the lower line.
Scroll with key and through the scroll list. All mea-
suring channels and their absolute values can be used for
the calculation.
The following calculation functions are available:
• -: Y = CH1 - CH2
• +: Y = CH1 + CH2
• (+)/2: Y = (CH1 + CH2)/2
• |-|: Y = |CH1 - CH2|
Press ENTER.
