[New Product] ETCR3660C Handheld DC Resistance Tester - DC resistance tester with Bluetooth communication function

Recently, Guangdong ETCR Electronic Technology CO.,Ltd. released a new product, the ETCR3660C Handheld DC Resistance Tester, primarily used for measuring the resistance of transformer windings, cable conductors, contact resistance of switches, plugs, and relays, metal riveting resistance, coil, motor, and transformer winding resistance, junction resistance between metal components, welding point resistance, parallel connection resistance of batteries, as well as wire length measurement calculations. The instrument is compact and lightweight, equipped with a large-capacity lithium battery pack, making it especially suitable for outdoor construction sites. It is widely used in building quality inspection stations, supervision companies, construction units, lightning protection companies, power departments, ship and locomotive factories, etc.

ETCR3660C Handheld DC Resistance Tester adopts microprocessor technology and precision four-wire method testing, ensuring accuracy and reliability. The instrument has two measurement modes: automatic measurement and manual measurement. In automatic measurement mode, the instrument automatically selects the range and test current range, while in manual measurement mode, users can manually select the range and current range to meet different requirements. The instrument also features automatic discharge, alarm function, and automatic shutdown. The ETCR3660C Handheld DC Resistance Tester consists of a main unit, monitoring software, test leads, charger, USB communication cable, etc. With a 5-inch touch color screen and handheld structure, the instrument has Bluetooth communication, allowing users to perform tests or view test results on their mobile phones after installing the app, making on-site use particularly convenient. The instrument can store 600 sets of data and can be connected to a computer via the USB interface and monitoring software, which has functions such as reading, viewing, and saving historical data.

Product Features:

1.Handheld structure, convenient to carry, with a simple touch color screen operation.
2.Two measurement modes: automatic measurement mode adjusts the test current according to the load, manual measurement mode has 7 current range options.
3.Test current range: AUTO, 10A, 5A, 1A, 100mA, 10mA, 1mA.
4.Maximum output voltage of 24V, maximum test current of 10A, fast testing speed suitable for transformer measurements.
5.With discharge function, automatically discharges after testing, with clear discharge indication to avoid misoperation.
6.Alarm function, allowing users to set resistance alarm thresholds.
7.Clock function.
8.Bluetooth communication function.
9.USB communication interface.
10.Rechargeable lithium battery.
