Digital Multimeters

GAOTek offers digital multimeters (DMMs), also known as volt-Ohm meters or VOMs, provide several electronic measurements such as the voltage, current, and resistance within one hand-held device. Digital Multimeters are used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms). It is a standard diagnostic tool for technicians in the electrical/electronic industries. These digital multimeters combine the testing capabilities of single task meters such as voltmeter (measuring volts), ammeter (amps) and ohmmeters (ohms). Measurement data are displayed as numerical values on the LCD display and they also alert the user to any pertinent symbols and warnings. These instruments can do auto-ranging and they are used to check the battery life of AA batteries and HT batteries and blown out fuses. The devices hold the maximum value on the screen so that users can probe without looking at the digital multi-meter.

Functions of Digital Multimeters

GAO Tek’s digital multimeters help to measure voltage in AC and DC circuits. These devices are widely used to perform diode tests and temperature tests. They measure the resistance of complete circuits or individual components. The digital multimeters also provide measurements of flowing current in AC and DC circuits. They are designed to measure transistor gains as well as the capacitance, frequency, pressure, vacuum, and battery.

Features

GAOTek’s digital multimeters are portable and well-constructed. Some components of the Digital Multimeter include the Display which is an easy-to read LCD one with automatic zero adjust. They have the buttons for selecting various options, a dial (for selecting measurement values like volts, amps, ohms) and input jacks where test leads are inserted. The devices have the data hold feature that captures the information on screens and holds three multiple tests. The auto range feature enables digital multimeters to change their internal range according to the requirement to detect the correct voltage, current, or resistance of the circuit. The auto polarity is also added in order to show the polarity of the current.

Applications and Industries

Digital multimeters are designed to measure the current that transceiver of digital multimeter draws to estimate how long emergency power system will last during a blackout. They can also be used to troubleshoot electrical problems in a wide array of industrial and household devices such as electronic equipment, motor controls, domestic appliances, power supplies, and wiring systems.
