DC Resistance TesterQuoteProduct Introduction：

DC resistance tester, also known as DC resistance measuring instrument, DC resistance meter, transformer DC resistance tester, DC resistance detector, DC digital bridge, etc.

Overview:
Advanced technology with precision measurement.
The DC resistance tester offers measurement currents of 1A, 3A, 5A, 10A, 20A, 30A and other ranges. The instrument consists of a constant current power supply and voltage signal detection unit with a 5-digit LCD display. Adjustable output current makes it suitable for DC resistance measurement of various small and medium transformers.

Feature Certificate

1. High-speed 16-bit A/D converter for stable, repeatable measurements.

2. Programmable current source with 1000 ranges, auto-controlled by MCU for wide measurement range.

3. Fast response, tap switch can be changed during measurement.

4. Intelligent design auto-detects loose or broken test leads.

5. Complete back EMF protection with auto discharge indication.

6. Displays measurement current and time.

7. Smart power management reduces internal heating.

8. Stores 120 measurements, non-volatile.

9. Full Chinese menu with operation prompts, intuitive and convenient.

Safety Measures

1. Read this manual carefully before using the instrument.

2. Operators should possess general electrical knowledge.

3. Avoid using the instrument in rain, corrosive gas, excessive dust, high temperature, direct sunlight, and similar environments.

4. Avoid severe vibration.

5. After testing, wait until the discharge alarm stops before powering off and removing test leads.

6. When measuring no-load tap-changing transformers, wait until the discharge indicator alarm stops before switching taps.

7. Do not move test clips or power supply wiring during testing.
