Introduction:

Handheld DC Resistance Tester, also known as transformer DC resistance tester, DC low-value resistance tester, which mainly used to measure transformer winding resistance; cable conductor resistance; contact resistance of switches, connectors and relays: metal riveting resistance winding resistance of coil, motor and transducer; connection resistance between metal components; welding point resistance: Battery parallel connection resistance; wire length measurement and calculation, etc.

The instrument with small size and light weight, and is equipped with a large-capacity lithium battery pack, which is especially suitable for use on outdoor construction site.

lt is widely used in construction quality inspection station, supervision company, construction units, lightning protection companies, electric power departments and ship engine factory, etc.

Handheld DC Resistance Tester adopt with the microprocessor technology and precision 4-wire method to test, accurate and reliable.

The instrument with two measurement modes: automatic measurement and manual measurement. Automatic measurement mode: The instrument automatically select the measurement range and test current gear, manual measurement mode: users can choose their own measurement range and current gear to meet the requirements of user on different occasions,

also has the functions of automatic discharge, alarm and automatic shutdown, etc.

Handheld DC Resistance Tester consist of host, monitoring software, test line, charger, USB communication line, etc.

The instrument adopt with 5 inch true-color touch screen, has Bluetooth communication, and after installing the APP, can perform test operation or view test result on your mobile phone, which is particularly convenient for on-site use.

The instrument can store 600 groups of data, and is connected to the computer through the USB interface and monitoring software. The monitoring software has functions such as reading, reviewing, saving, reporting, and printing historical data.

Function Features:

Handheld structure, easy to carry, true-color touch screen is simpler to operate.

Two measurement modes, automatic measurement mode: the test current can be automatically selected according to the load. Manual measurement mode: There are 7 gears to test current

Test current gear: AUTO, 10A, 5A, 1A, 100mA, 10mA, 1mA

Max. output voltage is 16V, the max. test current is 10A, fast-speed testing, and it can be applied to transformer measurement.

With discharge function, which is automatically discharged after the test, and the discharge instructions are clear to avoid misoperation.

Alarm function, can setting the resistance alarm threshold.

Clock function.

Bluetooth communication function.

USB communication interface.
