WDZL-100S Handheld Loop Resistance Tester

1. It has various protection functions such as back EMF impact, line interruption during testing, power failure, power supply overheating, etc., which can reliably protect the back EMF impact on the instrument, and synchronously sound an alarm.

2. Intelligent power management technology, the instrument always works in the minimum power state, effectively saving energy and reducing heat generation.

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 resistance of the test wire on the test results.

6. Seven-inch high-brightness touch color LCD, clear display under strong light, full touch screen operation, free switching between Chinese and English

7. The instrument comes with a perpetual calendar clock and power-down storage, which can store 1,000 sets of test data for reference at any time.

Product Details

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.
