Product feature and application

1. Can be powered by either a lithium battery or a 220V AC power supply. With a straightforward and user-friendly testing procedure, a single charge allows for the continuous testing of more than 100 transformers regarding turns ratio and connection group.
2. Includes a blind testing feature that enables turns ratio and connection group testing, even when the configuration of high/low voltage connections is not known.
3. Enhanced functionality beyond traditional transformers, Z-type transformers, and PT testing to encompass CT ratio and polarity testing, thus widening its range of applications.
4. Extensive measuring range and great precision: The ratio measurement reaches up to 10,000, with a guaranteed accuracy of 0.3% at the upper limit of 10,000.
5. All-embracing safeguarding functions such as protection against reverse connection and output short circuit.

6. Der 5,6 Zoll große, industrietaugliche LCD-Farbbildschirm mit hoher Helligkeit gewährleistet eine klare Sicht, selbst bei starkem Sonnenlicht.
7. Furnished with an external printer for easy data printing.
8. Facilitates data preservation with support for both internal storage and USB flash drives.

FAQ

1)What is the transformer turns ratio measurement range of the MEBC-WYT3 Handheld Transformer Turns Ratio Tester? What is the test accuracy corresponding to its maximum range?

Answer: The turns ratio measurement range of this instrument is 0.9 to 10000. The test accuracy corresponding to the maximum range (greater than 3000) is ±(reading ×0.3% + 2 digits).

2)What power supply methods does the MEBC-WYT3 Handheld Transformer Turns Ratio Tester support? How many transformers can it continuously test for turns ratio and connection group after a single full charge?

Answer: The instrument supports adaptive power supply from lithium batteries and 220V AC power. After a single charge, it can continuously perform turns ratio and connection group tests on over 100 transformers.

3)What is the "blind test function" of the MEBC-WYT3 Handheld Transformer Turns Ratio Tester? Can connection group parameters be manually modified during this function?

Answer: The blind test function enables the instrument to accurately determine the turns ratio and connection group even when the high/low voltage connection configuration and group of the test specimen are unknown. Within the "Blind Test Function" menu, the connection group is fixed to "Auto" and cannot be manually altered; the instrument automatically determines the connection group.
