100A 200A 300A DC Contact Loop Resistance Tester for Power System
I.Overview
The HZ-5300 Contact Resistance Tester is a high-precision, digital switch detection instrument carefully developed by the company in accordance with the IEC standard and the relevant regulations of the latest electric power implementation standard DL/T845.4-2004 of the People's Republic of China, using its own technical advantages. The instrument uses high-frequency high-power constant-current switching power supply technology, which can measure micro-ohm contact resistance. It is widely used in the measurement of contact resistance, loop resistance of various switches and electrical appliances, and contact resistance of cables, wires, and welds. The instrument has accurate measurement data and stable performance. It can meet the requirements of on-site high-voltage switch maintenance and high-voltage switch factory loop resistance testing in electric power and power supply departments Claim. The output current and measuring resistance are simultaneously output on the 65K true color LCD, and the measurement results can be voltage output or stored in a USB flash drive. The power-off storage can satisfy data query at any time.
II.Main technical indexes
1. The test current is large, which fully meets the requirements of the national standards for testing contact resistance.
2. High output voltage and wide measuring range.
3. The test current comes from a high-precision high-current constant-current power supply, without manual adjustment, and the test is rapid and accurate.
4. The four-terminal wiring method is adopted, which effectively eliminates the influence of the test wire resistance on the test results.
5. The 65K true color LCD with ultra-small pixels of 320X240 dot matrix,
6. The instrument comes with a perpetual calendar clock and power-down storage, which can automatically store 1000 sets of test data for reference at any time
7. The instrument is equipped with a micro printer, RS232 and USB interfaces, which can communicate with a computer and store in a U disk
8. Intelligent power management technology, the instrument always works in the minimum power state, effectively saving energy.
