4.3 Torch and Backlight 1） If need use Torch, Press“ ” button 2 second then open the Torch.， Around 15 seconds can closed automaticly.If you need re-open the Torch, please press the button 2 second 2）The Torch flashlight is LED, and its working current is large. Although the meter is equipped with timing circuit (timing time is about 15 seconds), frequent use of the Torch will shorten the battery life, so it is necessary to use the Torch as little as possible. -

2) " "sign indicates that the input voltage or current should not exceed the indicated value, which is to protect the internal wiring from damage. 3) Place the changeover switch in the desired measurement function and range. 4) When wiring, connect the common test leads and connect the live test leads. Remove the live test line when removing the wiring. - Page 17 Test current: 1）Press button power on the meter 2) Connect Red /black test leads to COM and 10A input jack 3) Disconnect the circuit to be tested. Connect the black test pen to one end of the disconnected circuit (the lower voltage) and connect the red test lead to the other end of the circuit that is broken (its voltage is high).
- Page 18 In the circuit, the normal diode should produce a forward voltage drop of 0.5V to 0.8V; however, the reverse bias reading will depend on the change in resistance of the other 4.11 Buzzer On/Off Test Warning Risk of electric shock. To avoid damage to the meter or the device under test, all power to the circuit under test should be cut off and all high voltage capacitors should be fully discharged before the beep on-off test.
