FAQ
Q1: What is the maximum storage capacity of test data?
A: Up to 1000 groups, old records will be overwritten when full, please export in time.
Q2: When can I remove the test cable after measurement?
A: Wait until discharge indication is finished to avoid inductive discharge danger.
Q3: Can I test three-phase and single-phase transformers?
A: Yes, support three-phase automatic test, single-phase test and connection group analysis.
Q4: What is the accuracy of transformation ratio test?
A: 0.1% within 0.8–1000, 0.2% within 1000–2000, 0.5% within 2000–5000.
Q5: Is it necessary to input rated transformation ratio?
A: If not input, only measured ratio will be displayed, and error will not be calculated.
