Multimeter 2000 Counts Digital Multimeter with DC AC Voltmeter and Ohm Volt Amp Tester; SEE MORE >>>
The principle of the multi-meter and the instruction for the use of the multi-meter
The ammeter can be converted into a voltmeter, an ammeter with a larger range, or an ohmmeter . If they are properly combined, they can share a single meter and become a multi-meter.
Purpose
Measure AC/DC voltage, AC/DC current, resistance value, capacitor capacity, inductance, audio level, frequency, transistor NPN or PNP current magnification β value, etc.
Multimeter classification
There are ordinary multimeters and digital multimeters.
Instructions for use
Pay attention to the range when using it. When not in use, turn the selector switch to the OFF block or the highest AC voltage block or set the switch to ohms files.
Before starting the measurement, it is necessary to perform mechanical zero adjustment, and use a screwdriver to turn the surface knob to make the pointer point to the zero-scale position
The principle of multimeter
A multi-meter is a multi-purpose instrument that can generally be used to measure DC and AC current, DC and AC voltage, and resistance, etc., and each measurement has several ranges.
⑴The principle of measuring DC current and DC voltage is the same as that of DC ammeter and DC voltmeter.
⑵Measuring resistance
