characteristic: 1. AC/DC dual-purpose: lithium battery power supply or 220V AC charger power supply adaptive. 2. The transformer ratio group of 100 transformers can be continuously measured in one charge. 3. Intelligent charging management, remaining power display, low power alarm, automatic backlight adjustment, and energy saving. 4. Full three-phase sine inverter power output, output voltage automatic adjustment, with soft start and soft stop functions, so the test speed is fast and the accuracy is high. 5. Three-phase transformer, single-phase transformer, PT, Z-type transformer transformation ratio, group, polarity test function. 6. It has the function of blind test, that is, when the high and low voltage connection modes are not known, the transformation ratio and group test shall be carried out. 7. CT transformer specific polarity test function. 8. Angle difference test function is available during single-phase test. 9. The tap gear can be tested to 197. 10. Wide test range, up to 10000. 11. High and low voltage reverse connection protection function. 12. Output short circuit protection function. 13. Clock and date display without power failure; The data storage mode is divided into local storage and USB flash disk storage. The local storage can store 500 pieces of test data, and the local storage can be transferred to USB flash disk; The USB flash disk storage data format is Word format, which can be edited and printed directly on the computer. 14. Small size, light weight, easy to carry and use. Technical parameters: Range: 0.9~10000 Accuracy: ± (reading × 0.1%+2 words) (≤ 500) ± (reading × 0.2%+2 words) (more than 500 but less than or equal to 3000) ± (reading × 0.3%+2 words) (more than 3000) Resolution: 0.9 ~ 9.9999 (0.0001) 100 ~ 999.99 (0.01) 10000 and above (1) 10~99.999(0.001) 1000~9999.9(0.1) Working power supply: built-in battery or external charger, charger service conditions, input 100-240VAC, 50/60Hz Charging time: about 5 hours Instrument weight: 1.34 kg Instrument volume: 246mm (length) × 156mm wide × 62mm high Operating temperature: - 10 ℃~50 ℃ Relative humidity: < 90%, no condensation
