10A DC resistance tester

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. The maximum output voltage of the instrument is 24V, which facilitates the selection of larger test currents for high resistance values and improves testing speed

3. The instrument adopts a new power technology, with multiple current levels and a wide measurement range. It can automatically select the current according to the load and is suitable for measuring the DC resistance of small and medium-sized transformers and voltage transformers.

4. It has multiple protection functions such as back electromotive force impact, disconnection and power outage during testing, and overheating of the power supply. It can reliably protect against the impact of back electromotive force on the instrument and synchronously sound an alarm.

5. It has the function of converting copper and aluminum materials to any temperature, allowing for touch input of any winding temperature and temperature conversion.

6. Intelligent power management technology ensures that the instrument operates at its minimum power state, effectively saving energy and reducing heat generation.

7. Seven 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.

10A DC resistance testerPrecautions

1. After measuring the inductive load, the test line cannot be directly removed to avoid endangering the safety of testing personnel and equipment due to inductive discharge. The output terminal of this machine is equipped with a discharge circuit. After resetting the instrument, the inductor will release energy through the instrument. The test line can only be removed after the discharge indicator is completed.

2. For no-load tap changers, it is not allowed to switch tap changers during the measurement process.

3. If the power suddenly shuts down during the measurement process, this machine will automatically start discharging. Please do not immediately remove the wiring, wait at least 30 seconds before removing the wiring.

4. When measuring, other untested windings should not be short circuited to ground, otherwise it will cause the transformer magnetization process to slow down, the data stabilization time to be prolonged, or the values to be incorrect.

5. Please check the power supply voltage before starting up: AC 220V ± 10%, 50Hz.

6. Please confirm that the tested equipment has been powered off and disconnected from other live devices during the experiment.

7. The casing must be reliably grounded during the experiment.

8. During the experiment, unrelated items are not allowed to be stacked on or around the equipment panel.

9. When replacing the fuse and accessories, please use the same model as this instrument (see technical specifications for details)

10. This instrument should be moisture-proof and oil proof.
