Digital Multimeters

GAO Tek offers digital multimeters (DMMs), also known as volt-Ohm meters or VOMs, which provide several electronic measurements such as the voltage, current, and resistance within one hand-held device. Measurement data are displayed as numerical values on the LCD display and they also alert the user to any pertinent symbols and warnings. Digital multimeters are common and are widely used by professionals due to their cost and precision. Moreover, 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. Digital multimeters check the power supply voltage on the new power supply and also reduce the number of resistors.

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.


GAO Tek’s digital multimeters are portable and well-constructed. By using digital multimeters, it is easy to read at all angles and the majority of lighting levels and proceed Diode testing. Digital multimeters measure all electrical characteristics and have the auto-off option to keep from draining the batteries. They also feature an easy-to-read digital LCD display and automatic zero adjust. 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.
