Introducing the ES3070 handheld DC resistance tester, a versatile and dependable tool known by a variety of labels such as transformer DC resistance tester, DC resistance fast tester, and ground continuity tester. Harnessing the power of microprocessor technology and employing a four-wire testing approach, this handheld piece of equipment guarantees safety, accuracy, and reliability.
This workhorse of a device has a wide array of applications. You can use it primarily to calculate the resistance of transformer windings, including transformer winding resistance and grounding down conductor continuity test. It can also measure cable wire resistance, the contact resistance of switches, connectors, and relays, as well as the resistance of coils, motors, and equipment casings. Other uses include measuring the connection resistance between various metal components, making it vital in diverse fields including telecommunications, electric power, meteorology, computer rooms, oil fields, power distribution lines, and even gas stations.
The ES3070 handheld DC resistance tester comes as a comprehensive package comprising of a host, monitoring software, test line, and communication lines. Its handheld and portable design perfectly caters to on-the-go testing needs. Plus, its charging capability eliminates the need for on-site electricity. The icing on the cake is an interactive full-color large-screen LCD display and touch screen operation, which makes using this device a breeze. Not to forget, it features a storage capacity for up to 500 sets of data and a resistance measurement range of 10.0uΩ-50.00KΩ, boasting an accuracy of 0.2%.
The package includes a host, an instrument case, a CD, a USB cable, two test leads (one red and one black), a charger, and a user manual. Its resolution is 0.1uΩ, and the measurement technique used is the four-wire method. It comes with a large capacity lithium battery, backlight for visibility in dim places, a full-color LCD display, touch screen operations, an overload protection, and an automatic discharge.
Additional features include automatic shutdown after 15 minutes of inactivity, a standby power consumption of 120mA (20% brightness), and a maximum power consumption during measurement of 27W. The temperature and humidity it can tolerate range from -10°C~50°C and below 70%RH respectively for working conditions, and -20°C~60°C and below 70%RH respectively for storage conditions. It also comes with English Display support.
