| Polarity error indication | When the working current (voltage) reaches more than 5% of the rated current (voltage) and the error exceeds 180%, there should be a polarity indication. | |
| Attention: If the polarity indication still does not appear after exceeding 10% of the rated working current (voltage), it indicates a fault. Please do not increase the current (voltage) again to avoid burning out the instrument. | ||
| Variable ratio error indication | When the working current (voltage) reaches more than 5% of the rated current (voltage) and the error exceeds 30% but is less than 180%, there should be a ratio error indication. | |
| Insulation and voltage withstand tests and instructions | Terminal TX() is connected to the terminal | |
| The power socket can withstand a voltage of 1.5kV and a 1-minute withstand voltage for the casing | ||
