Digital 3 Phase Rotation Meter, Portable Tester for Electrical Phase Sequence Verification

Feature: 1. Multifunction: Detects phase open condition and phase sequence using LED indicators and buzzer. 2. Frequency Range: 20 Hz to 400 Hz; equipped with red, green, and yellow LEDs and buzzer for clear status indication. 3. Stable Performance: Delivers fast, accurate, efficient, and reliable measurements; designed for ease of use and safety. 4. Durable Construction: Made from high-quality ABS material—lightweight, wear-resistant, corrosion-resistant, and built for long service life. 5. User-Friendly Design: Includes dedicated test clips; attach clip to the metal probe of the test lead and tighten for secure clamping during measurement. Specification: Item Type: 3-Phase Rotation Tester Material: ABS Model: SM852B Purpose: 3-phase AC measurement Measurable Frequency Range: 20 Hz – 400 Hz Continuous Use Time: Up to 60 minutes at 200 V AC, up to 4 minutes at 600 V AC Package List: 1 × 3-Phase Rotation Tester 3 × Test Clips 1 × User Manual 1 × Portable Cloth Bag Safety Notes: 1. This is high-voltage test equipment. Before use, inspect the device for damage. Discontinue use if any of the following occur: visible shell damage (e.g., cracks), damaged insulation on test leads, severe impact during transport, or prolonged storage in damp or humid conditions (e.g., bathroom). 2. Do not open the casing during measurement. 3. During measurement, high voltage is present at the test leads. Avoid direct contact with exposed wires or metal parts of the leads. 4. Even when phase indicators are unlit, voltage may still be present—exercise caution to prevent electric shock. 5. Do not measure circuits exceeding 600 V. 6. Limit continuous operation to 60 minutes at 200 V AC and 4 minutes at 600 V AC. 7. Do not use outdoors in rain or in humid environments. 8. Keep the device away from water, corrosive liquids, direct sunlight, and high-temperature or high-humidity environments to maintain performance. 9. Only qualified personnel may open the device casing. 10. Operators must have appropriate training in high-voltage measurement and must follow all instructions in the manual.
