If the deviation E4 caused by high probe or auxiliary probe resistance is
higher than specified W flashes. Measured values are outside of the
specified operating uncertainty.
Measuring time: 8 seconds (average from when START is pressed)
Limit input: Tester retains set value even if instrument is turned
off (assuming battery power supply is sufficient)
If Tester detects stray interference voltage ≥20 V, W is displayed and the
measurement is not started.
