FAQ

1)How does the MOEORW-W4300 Transformer Parameter Tester determine correct wiring during three-phase transformer no-load testing?

Answer: During three-phase transformer no-load testing, the upper left corner of the test data page displays a phasor diagram of the test voltage and current. If wiring is correct, the phasor diagram displays normally. If wiring is incorrect, the page will directly prompt "Wiring error, please power off and check," helping users quickly troubleshoot wiring issues.

2)What data export and storage-related functions does the MOEORW-W4300 Transformer Parameter Tester support?

Answer: The instrument's data-related functions include: 1. USB interface for connecting USB drives to export data and upgrade software; 2. Built-in real-time clock automatically records test date and time for convenient result management; 3. Power-off storage and browsing capability, storing up to 500 test result sets; 4. Supports data transfer via computer connection; 5. Equipped with a panel-mounted thermal printer for rapid on-site printing of test results.

3)How should the MOEORW-W4300 Transformer Parameter Tester be handled if the screen suddenly goes black during operation?

Answer: If the screen suddenly goes black during use, press the instrument's reset button directly and restart the measurement. This troubleshooting method is sourced from the product manual's common troubleshooting section and can quickly resolve screen blackout issues not caused by hardware damage.
