HZ-5100-I Handheld Digital Loop Resistance Meter 100A

I. Overview

The hand-held loop resistance tester is a high-precision, digital switch detection instrument carefully developed by the company in accordance with the relevant provisions of IEC standards and exerting its own technical advantages. The instrument adopts high-frequency high-power constant-current switching power supply technology, and can measure micro-ohm contact resistance. It is widely used in the measurement of contact resistance, loop resistance of various switches and electrical appliances, as well as the contact resistance of cables and wires, and welding seams. The measurement data of the instrument is accurate and the performance is stable. Require. The output current and the measured resistance are simultaneously output on the seven-inch high-brightness touch color LCD. The measurement results can be output in voltage or stored in a U disk. The power-down storage can meet 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.
