ETCR3660A micro ohmmeter

ETCR3660A micro ohmmeterAlso known as DC resistance tester or DC low value resistance tester, the instrument adopts microprocessor technology and precise four wire method testing, which is accurate and reliable. Mainly used for measuring the resistance of small transformer windings; Grounding conductivity resistance; Cable conductor resistance; Contact resistance of switches, connectors, and relays; Metal riveting resistor; Coil, motor, transformer winding resistance; Connection resistance between metal components; Welding contact resistance; Parallel connection resistor of battery; And measurement and calculation of wire length. The instrument casing adopts a waterproof protective box, which is anti-collision, anti drop, waterproof (protection level IP65), sturdy, safe and durable. The instrument is also equipped with a large capacity rechargeable lithium battery pack, especially suitable for outdoor construction sites. Widely used in construction quality inspection stations, supervision companies, construction units, lightning protection companies, power departments, ship and locomotive factories, etc.

The instrument has two measurement modes: automatic measurement and manual measurement. In automatic measurement mode, the instrument automatically selects the range and test current gear. In manual measurement mode, users can choose the range and current gear themselves to meet the requirements of different occasions. The instrument also has clock function, alarm function, automatic shutdown function, etc.

The ETCR3660A DC resistance tester consists of a host, test line, charger, USB communication line, etc. The instrument adopts a 5-inch touch color screen, with two operation modes of touch screen and buttons. The test gear, test resistance, and test current are displayed on the same screen. The instrument has Bluetooth communication, and after installing the APP, the test results can be viewed on the mobile phone. It is particularly convenient for on-site use. The instrument can store 1000 sets of data and connect to a computer through a USB interface and monitoring software. The monitoring software has functions such as historical data reading, viewing, saving, and reporting.
