3.10.10.1 Loading and saving the arbitrary function
The100sequencesofthearbitraryfunction,whichcanbemanuallyconguredwiththecontrolpanelofthede-
vice and which are applicable either to voltage (U) or current (I), can be saved to or loaded from a common USB
stickviathefrontsideUSBport.Generally,all100sequencesaresavedorloadedusingatextleoftypeCSV
(semicolon separator), which represents a table of values.
In order to load a sequence table for the arbitrary generator, following requirements have to be met:
• The table must contain exactly 100 rows with 8 subsequent values (8 columns) and must not have gaps
• Thecolumnseparator(semicolon,comma)mustbeasselectedbyparameter“USBleseparatorformat”;italso
denesthedecimalseparator(dot,comma)
• ThelesmustbestoredinsideafoldercalledHMI_FILESwhichhastobeintherootoftheUSBdrive
• ThelenamemustalwaysstartwithWAVE_UorWAVE_I(notcase-sensitive)
• Allvaluesineveryrowandcolumnhavetobewithinthespeciedrange(seebelow)
• Thecolumnsinthetablehavetobeinadenedorderwhichmustnotbechanged

► How to load a sequence table (100 sequences) from an USB stick
1. Do not plug the USB drive yet or remove it.
2. Access the function selection menu of the function generator with
MENU -> Function Generator -> Arbitrary -> U/I, to see the main screen
of sequence selector, as depicted to the right.
3. Tap touch area , then and follow the instructions
onscreen.Ifatleastonevalidleshasbeenrecognized(forleand
pathnamingseeabove),thedevicewillshowalistoflestoselect
from with .
4. Tap touch area inthebottomrightcorner.Theselectedleisthencheckedandloaded,ifvalid.
Incaseitisnotvalid,thedevicewillshowanerrormessage.Thenthelemustbecorrectedandthe
steps repeated.
