Audited Supplier The HVD-300A circuit resistance tester is a high-precision and digital switch detection instrument carefully developed by the company in accordance with IEC standards and the latest power execution standard DL/T845.4-2004 of the People's Republic of China, leveraging its own technical advantages. This instrument adopts high-frequency high-power constant current switching power supply technology and can measure micro ohm level contact resistance. Widely used for measuring the contact resistance, circuit resistance, and contact resistance of cables, wires, and welds of various switches and electrical appliances. The instrument has accurate measurement data and stable performance, meeting the requirements of on-site high-voltage switch maintenance and high-voltage switch factory circuit resistance testing in power and power supply departments. The output current and measurement resistance are simultaneously output on a 65K true color LCD, and the measurement results can be output as voltage or stored on a USB flash drive. Power down storage can meet the needs of data query at any time.
1. The testing current is high and fully meets the national standard requirements for testing contact resistance.
2. High output voltage and wide measurement range.
3. The testing current comes from a high-precision high current constant current power supply, without the need for manual adjustment, and the testing is fast and accurate.
4. The use of four terminal wiring method effectively eliminates the influence of test wire resistance on the test results.
5. A 65K true color liquid crystal with ultra small pixel points on a 320X240 lattice.
6.The instrument comes with a perpetual calendar clock and power down storage, which can automatically store 1000 sets of test data for easy access at any time.
7.The instrument is equipped with a micro printer, RS232, and USB interface, which can communicate with computers and store on a USB drive.
8.Intelligent power management technology, instruments always work at the minimum power state, effectively saving energy.
