3.6 Measuring Continuity
Under continuity test, when 200 Ω range is selected, the multimeter alerts you with a beep when a
reading is below a threshold resistance level of 10 Ω. For other ranges, the beeper will sound if a reading
is below a threshold resistance level listed in table 3-1. This beep will sound within less than half a
second when reading measured is below the threshold.
