Product introduction

Musktool-ETCR3 660 series DC resistance tester is also known as transformer DC resistance tester, DC low-value resistance tester, ground continuity tester, the instrument adopts microprocessor technology, precise four-wire method test, accurate and reliable. Mainly used to measure transformer winding resistance; grounding conduction resistance; cable wire resistance; contact resistance of switches

connectors, and relays; metal riveting resistance; winding resistance of coils, motors, and transformers; connection resistance between

metal components; electric welding point resistance ; Battery parallel connection resistance; and wire length measurement and calculation. The instrument shell is made of a waterproof protective box, which is strong, safe and durable for anti-collision, drop-proof and waterproof (protection grade IP65). The instrument is also equipped with a large-capacity rechargeable lithium battery pack, which is especially suitable for use in outdoor construction sites. Widely used in construction quality inspection stations, supervision companies, construction units, lightning protection companies, electric power departments, ship locomotive factories, etc.

The instrument has two measurement modes: automatic measurement and manual measurement. In the automatic measurement mode, the instrument automatically selects the range gear and test current. In the manual measurement mode, there are 7 range gear options to meet the requirements of users in different occasions. The instrument has the function of calculating resistance at 75°C temperature conversion, which can be compensated and converted according to the temperature and material of the test product. The instrument also has automatic discharge function, alarm function, clock function, automatic shutdown function and so on

Features

  1. The instrument is controlled by a high-speed single-chip microcomputer, with fast response, stable measurement and easy operation.

  2. Two measurement modes, automatic measurement mode: the test current can be automatically selected according to the load. Manual measurement mode: There are 7 levels of test current 10A, 5A, 1A, 100mA, 10mA, 2mA, 1mA to choose from.

  3. Adopt 480×854 true color LCD touch screen, clearly visible under strong light, touch screen/button dual-use. Large-capacity lithium battery and waterproof instrument box are suitable for outdoor use.

  4. With Bluetooth communication, after installing the APP, you can perform test operations or view test results on your mobile phone.

  5. The instrument has a USB interface and monitoring software, which can communicate with the computer.

  6. The protection function is perfect, which can reliably protect the impact of the back electromotive force on the instrument, and the performance is more reliable.

  7. With discharge function, automatic discharge after test, clear discharge indication, avoid misoperation.

  8. It has the function of converting resistance, which can compensate and convert the temperature and material of the test product.

  9. Alarm function, the resistance alarm value can be set.

  10. Automatic shutdown function, automatically shuts down after 15 minutes of no operation.
