Measuring range: 12 - 1000V pay attention to the default detection range of the tester's AC voltage: about 48 lOOOV. Press AC voltage detection range switch button (S), detection range indicator light, and the detectable voltage range of the tester is about 121000V. Press the AC voltage detection range switch button (S) again, the detection range indicator light, and the detectable voltage range of the tester is about 48 lOOOv. Auto shutdown function, when there is no operation of the tester and no voltage signal detected by the tester within 5 minutes, the tester will shut down automatically. Low battery voltage indicator, when the battery voltage is lower than about 2.6V, the indi cator power flashes 3 times while the buzzer makes a sound and then turns off. Replace the battery in time.
