| voltage | a对x＜0.25VA (100V) | |
| Polarity error indication | When the operating current (voltage) reaches more than 5% of the rated current (voltage) and the error exceeds 180%, there should be polarity indication. | |
| If it is more than 10% of the rated operating current (voltage) and still does not show the due polarity indication, it indicates that there is a fault, please do not increase the current (voltage), so as not to burn the instrument. | ||
| Change ratio error indication | When the operating current (voltage) reaches more than 5% of the rated current (voltage), the error is more than 30% and less than 180%, there should be a ratio error indication. | |
| Insulation and pressure test and specification | Terminal TX() The terminal is connected | |
| The power socket can withstand 1.5kV and 1min of pressure to the shell | ||
