The PCAP touch function temporarily fails during EFT +/- 4KV testing. How can this be addressed?
When the power supply undergoes EFT testing, response pulses can cause output ripple and EMI, which can affect the PCAP touch panel's ability to detect minute voltage changes and pinpoint the touch location. Unexpected voltage changes can cause malfunctions, so it is recommended to use a power supply that meets EFT 4KV Criterion A to mitigate this issue.
