Data analysis details

The software carries out the data analysis according the ISO 9869-1 2014 standard section 7.1. It starts with analysing the longest possible multiple of the 24h measurement interval. If this interval does not fulfil the conditions specified within the ISO standard, the software seeks for the longest measurement interval fulfilling the specifications. If no interval >72h fulfils the specifications, then the software will flag the measurement as non ISO conformal.

The above figure demonstrates an example of a visualization of the data analysis procedure for a measurement duration of 8.5 days. The analysis period of the R-Value is calculated by taking the integer multiple of 24h from the measurement period (i.e. 8*24h). The R24 period is the same as the U-value analysis time without the last 24h. R2/3s and R2/3e periods are the integer multiple of 24h of the first and the last 2/3 of the analysis period.
