HZ-5300 Contact Resistance Measurement Equipment 300A

First, the introduction
HZ-5300 Contact Resistance Measurement Kit is a high-precision, digital switch detection instrument carefully developed by the company according to the IEC standard and the latest power implementation standard DL/T845.4-2004 of the People's Republic of China. The instrument uses high-frequency high-power constant-current switching power supply technology to measure micro-ohmic contact resistance. It is widely used in the contact resistance, loop resistance, cable and wire, weld contact resistance measurement of various switches and electrical appliances. The instrument measurement data is accurate and the performance is stable. It meets the high-voltage switch maintenance of the power and power supply departments and the loop resistance test of the high-voltage switch factory. Claim. The output current and the measuring resistor are simultaneously output on the 65K true color liquid crystal, and the measurement result can be the voltage output or the U disk storage, and the power failure storage can satisfy the data query at any time.

Second, the performance characteristics
1. The test current is large and fully meets the national standard requirements for testing contact resistance.
2. The output voltage is high and the measurement range is wide.
3. The test current comes from a high-precision high-current constant-current power supply, which requires no manual adjustment and is quick and accurate.
4. The four-terminal wiring method is adopted to effectively eliminate the influence of the test line resistance on the test results.
5. 320X240 dot matrix ultra-small pixel 65K true color LCD,
6. The instrument comes with a perpetual calendar clock and power-down storage, can automatically store 1000 sets of test data, anytime to check
7. The instrument is equipped with a micro printer, RS232 and USB interface, can communicate with the computer and U disk storage
8. Intelligent power management technology, the instrument always works in the minimum power state, effectively saving energy.
