        11. Highest seven digits display, high resolution of output and measurement (mV resolution: 1μV, Ω resolution: 1mΩ);

        12. Compact size, easy to carry, use anti-shock and anti-fall silicone shell to avoid accidental damage;

        13. Fully enclosed thin film touch button, long service life of 500,000-1 million times;

        14. Support two-wire, three-wire, and four-wire output and measurement of Ω (thermal resistance) signals;

        15. All signals can be automatically stepped and ramped, and any step (ramp) point and step (ramp) time can be set;

        16. Real-time recording of on-site detection data can be achieved to realize paperless recording function;

        17. External high-precision cold junction compensation probe can perform manual or automatic cold junction temperature compensation and setting;

        18. Adopt large-capacity high-performance polymer rechargeable batteries, continuous working time of more than 10 hours;

        19. Standard gold-plated test leads, less contact potential and contact resistance, to ensure high-precision calibration;

        20. Five-year warranty of the host, free lifetime accuracy correction, and lifetime service guarantee;

        21. Volume: 220 × 107 × 37mm, weight: 580g.
