Contact resistance tester/Micro-ohmmeter

Profile

Contact resistance instrument is a carefully developed high precision, digital switch detection instrument by the IEC standard And PRC's Latest electric power execution standard DL/T845.4-2004 Regulations. The Instrument adopt High frequency high power constant current switching power supply technology to detect the Micro ohm contact resistance. The instrument is widely used for varieties of the switches and Contact resistance of switches and electrical appliances, contact resistance and Power cables, contact resistance of welding seam detection.The measurement data is accurate and correct,high stability and satisfy the requirements of Power, power supply department on-site high-voltage switch repair and high voltage switch factory contact resistance test. Output

current and measurement resistance output at the same time in the 7-inch high brightness

touch color liquid crystal, measurement results can be stored on the U disk, power off storage can meet the data query at any time.

HLY-100M gives 50/100A output (2 positions), HLY-200M gives 50/100/150/200A output (4 positons).

1. The instrument can be controlled by the whole process of the instrument through the special software of the mobile phone, and the test data can be stored in a fixed format on the mobile phone, so as to facilitate data query at any time.

2. It has a variety of protective functions, such as reverse potential impact,disconnection,

power failure and overheat during the test,which can reliably protect the impact of reverse potential on the instrument and give synchronous sound alarm.

3. Intelligent power management technology,the instrument always works in the minimum

power state, effectively saving energy and reducing heat.

4. Output high voltage, measurement range is wide (0-100mΩ).

♦ Mobile phones download APP, control instruments through software, upload test data for easy reference.

♦ It has a variety of protection functions, such as back potential impact, disconnection and power failure during the test, power overheating, etc. It can reliably protect the impact of back potential on the instrument, and simultaneously give an audible alarm.

♦ Intelligent power management technology, the instrument always works at the minimum power state, effectively saving energy and reducing heat. High output voltage, wide measuring range.

♦ The test current is from a high-precision high-current constant-current power supply, without manual adjustment, and the test is fast and accurate.

♦ The four-terminal wiring method effectively eliminates the influence of the test line resistance on the test results.

♦ 7-inch high-brightness touch color LCD, clear display under strong light, full-touch screen operation, free switching between Chinese and English.

♦ The instrument is equipped with a perpetual calendar clock and power-off storage, which can store 1000 sets of test data for reference at any time.

♦ The instrument has RS232 communication and USB interface for computer communication and U disk data storage.

♦ With its own panel micro printer, it can print the measurement results in real time.
