(5) Continuity
The internal sounder activates if the resistance of the circuit under test is less than 20Ω. It will then turn off if the resistance is increased beyond 50Ω.
Response time is approximately 50 msec. overload Protection: 600V dc/ac rms max.

*2 The accuracy is specified with the backlight not activated.
*3 For accurate readings, do not use the mains power supply when measuring low-value capacitance.
*4 In order to ensure the best accuracy in measurement of a low value capacitance, note and subtract the stray capacitance
of the open-circuit test leads from subsequent measurements.
