Audited Supplier The HVD-200A 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 7-inch high brightness touch color LCD, and the measurement results can be output as voltage or stored on a USB flash drive. Power down storage can meet data query at any time.
1. The instrument can use Android phone or tablet, follow WeChat official account, download special APP, control the instrument through special software, store and upload test data for easy reference.
2. It has multiple protection functions such as back electromotive force impact, wire breakage and power outage during testing, power overheating, etc. It can reliably protect the impact of back electromotive force on the instrument and synchronously sound an alarm.
3. Intelligent power management technology ensures that the instrument operates at the minimum power state, effectively saving energy and reducing heat generation.
4. High output voltage and wide measurement range.
5. 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.
6. The use of four terminal wiring method effectively eliminates the influence of test wire resistance on the test results.
7. 7-inch high brightness touch color LCD, clear display under strong light, full touch screen operation, free switching between Chinese and English
8. The instrument comes with a perpetual calendar clock and power down storage, which can store 1000 sets of test data for easy access at any time
9. The instrument has Bluetooth communication, RS232 communication, and USB interface for computer communication and USB data storage.
10.Equipped with a panel mounted micro printer, it can print measurement results .
