DIGITAL MULTITESTER
An installer would have been familiar with the multi-tester. Because of these tools can provide information about the electrical current, voltage, resistance and amplifiikasi. This tool is also known as the VOM (Volt-Ohm meter) that can measure voltage (voltmeter), barriers (ohm-meter), and current (ammeters). There are two categories of multimeters: digital multimeter, or DMM (digital multi-meter) and analog multimeters. Each category can measure AC power, and DC power. UNI-T is a handheld device that implement digital technologies to obtain a very high degree of accuracy . In addition to providing high accuracy, the results can can see it digitally.
