Digital Multimeters are a type of measurement device used to test and measure a range of electrical properties such as voltage (volts), current (amps) and resistance (ohms). Using a digital output readout, the digital multimeter is connected to a device and measures typically the voltage and any resistances, giving you an output you can measure. Digital multimeters offer a wide range of AC and DC measurement capabilities to suit a variety of applications. Multimeters are essential tester tools for carrying out electrical work from home renovations to large scale installations.
They are commonly used in applications such as:

• Research Laboratory
• Development Laboratory
• Detection and Maintenance
• Calibration Laboratory
• Automatic Production Test
