FAQ
Q1: Can it test Z-type and rectifier transformers?
A: Yes, select Z-type mode in settings to support ZN/y, ZN/d and special transformers.
Q2: Why does the instrument always show "charging"?
A: Current gear is too large, please reset and select smaller current.
Q3: Does it support temperature conversion?
A: Yes, support copper/aluminum winding and convert to 75°C or other target temperature.
Q4: Can I switch tap changer during measurement?
A: Yes, instrument automatically refreshes data without reset.
Q5: How to export test data?
A: Support built-in print and USB flash drive storage export.
