Notes for continuity specifications:
1. Overload protection: 600 Vrms for short circuits with < 0.1 mA current.
2. Maximum open voltage is 1.4 V.
3. Built-in buzzer beeps continuously when the reading measured is less than 30 Ω and does not beep when the measured resistance is more
than 200 Ω. Buzzer may either sound or not between 30 Ω and 200 Ω.
4. Continuity indicator: 2.7 kHz tone buzzer.
