4.3.3.8 Leakage Setting
Please use the up and down arrow keys or the ENTER key and scroll the highlighted area to
the Leakage parameter. The display will appear as follows:
The Touch Current test can be configured to meter the leakage current in RMS or Peak. The
RMS/Peak configuration is set by the pressing the Leakage softkey while the Leakage-HI or
Leakage-LO parameter is highlighted.
RMS and Peak Definitions
RMS (Root-Mean-Square): For a sine wave, the RMS value is 0.707 times the peak value.
Peak: Peak (pk) is the maximum value, either positive (pk+) or negative (pk-), that the current
waveform attains.
For a sine wave without a DC component, the peak amplitude is equal to approximately 1.414
times the root-mean-square amplitude.
