9V Buzzer Tester Continuity Tester Test Measurement Inspection Detectors Continuity Tester With Multimeter Pen Wire/clip Wire

9V Buzzer Tester Continuity Tester Test Measurement Inspection Detectors Continuity Tester With Multimeter Pen Wire/clip Wire Features: This product has a buzzer prompt with a volume of about 100 decibels. It is also equipped with an indicator light prompt. 1. How to use: After turning on the test power supply, touch both ends of the tested wire. If an audible and visual alarm is issued, it means that the wire is conducting, otherwise it means that the wire is not conducting. 2. This product has a built-in 9V battery, and the battery can be replaced by opening the cover. As shown in the schematic diagram, if the red and black ends are not measured, the circuit is not conducting and there is no current consumption. 3. After the measurement circuit is connected, the loop current is about 20ma. This product is not suitable for measuring tiny electronic components, circuit boards, etc. Specifications: Part name: 9V buzzer tester Material: ABS Color: White Size: 63*45*20mm --You can test whether the cable is normal, whether the wire is normal, whether the PCB board cable is normal, and whether the product itself is normal. --Precautions: Do not use when the product is powered on or plugged in! Instructions for use: 1. This machine is mainly used to test the continuity of conductors such as wires, which is equivalent to the on/off position of a multimeter. It is simple and convenient to use. 2. How to use: touch the two ends of the wire to be tested with the test of this machine. If the machine emits an audible and visual alarm, it means that the wire is conductive, otherwise it is disconnected. 3. Short-circuit the test of this machine before testing.
