Electrician's screwdriver MS-18

Electrician's screwdriver MS-18 Electrician's screwdriver MS-18 is a simple multifunctional device that allows to determine the presence of alternating current voltage by a contact method in the range from 70 to 250 volts and by a noncontact method in the range up to 1000 volts. It also allows to determine the polarity of the permanent sources of supply in the range from 1.5 to 36 volts, test the circuit for continuity, for example for incandescent lamps or fuses, as well as to detect the microwave radiation.For testing the alternating-current mains for the presence of voltage, using a contact method, with the slot of the tester touch directly the circuit contact, the light-emitting diode will blink, indicating a phase.When testing by a noncontact method is held, take the tester for a metal tip and the other end of the tester bring to the place of testing. In case of voltage presence, the light-emitting diode will blink. In order to test the circuit for continuity, for example, the integrity of a filament in a bulb, touch with one hand the screw on the butt end of the tester. Then touch with the tip the central contact of the bulb, and with the other hand touch the base.If the thread is intact, the light-emitting diode of the tester will blink.Electrician's screwdriver MS-18 will become an irreplaceable assistant, both in the household and in industries and it will help you to carry out the necessary measurements quickly and efficiently.
