I.Overview
The hand-held Contact Resistance tester is a high-precision, digital switch detection instrument carefully developed by the company according to the IEC standard and the latest electric power executive standard of the People's Republic of China DL/T845.4-2004.The instrument uses high frequency high power constant current switching power supply technology, can measure the micro ohm level contact resistance. Widely used in all kinds of switches and electrical appliances contact resistance, circuit resistance and cable wire, welding line contact resistance measurement, the instrument measurement data is accurate, stable performance, meet the electric power, power supply department on-site high voltage switch maintenance and high voltage switch plant circuit resistance testing requirements. The output current and measuring resistance are output on the seven-inch high brightness touch color LCD at the same time. The measurement results can be output voltage or stored in THE U disk. The power off storage can satisfy the data query at any time.
II.Performance characteristics
1.It has a variety of protection functions such as back EMF impact, interruption of the line during the test process, power failure, and overheating of the power supply, which can reliably protect the impact of the back EMF on the instrument, and synchronously sound an alarm.
2.Intelligent power management technology, the instrument total work in the minimum power state, effective energy saving, reduce heat.
3.The instrument can be freely switched between Chinese and English, with high output voltage and wide measurement range.
4.The test current comes from a high-precision high-current constant-current power supply, without manual adjustment, and the test is fast and accurate.
5.The four-terminal wiring method is adopted, which effectively eliminates the influence of the test lead resistance on the test results.
6.Seven-inch high-brightness touch color LCD, clear display under strong light, full touch screen operation
7.The instrument can be connected to an external printer to print measurement data, which is convenient for paperless office. (optional)
8.The instrument comes with a perpetual calendar clock and power-down storage, which can store 1000 sets of test data for reference at any time.
