The <inline-formula><tex-math notation="LaTeX">$P_{st}$</tex-math></inline-formula> indicator is one of the parameters used in the power quality evaluation. The International Electrotechnical Commission (IEC) flickermeter with a complex signal chain structure is used for <inline-formula><tex-math notation="LaTeX">$P_{st}$</tex-math></inline-formula> measurements. The occurrence of <inline-formula><tex-math notation="LaTeX">$P_{st}$</tex-math></inline-formula> values greater than the limit value indicates the occurrence of flicker severity caused by voltage fluctuation. This article presents the analysis of the influence of the sampling rate on <inline-formula><tex-math notation="LaTeX">$P_{st}$</tex-math></inline-formula> measurement results. For analysis purpose, the analytical model of the IEC flickermeter signal chain has been prepared, considering the sampling rate of input voltage. Based on the prepared model, the possible effects of incorrect sampling rate selection in <inline-formula><tex-math notation="LaTeX">$P_{st}$</tex-math></inline-formula> measurements have been presented. The model test results have been compared with laboratory measurement results for two advanced metering infrastructure energy meters with built-in IEC flickermeter. The obtained laboratory measurement results indicate the occurrence of aliasing for tested energy meters, which causes <inline-formula><tex-math notation="LaTeX">$P_{st}$</tex-math></inline-formula> measurement disturbance.
