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. | |
Note: if it is more than 10% of the rated operating current (voltage), there is still no proper polarity indication, indicating a fault. Please do not increase the current (voltage) to avoid burning out the instrument. | ||
Variable ratio error indication | When the operating current (voltage) reaches more than 5% of the rated current (voltage) and the error exceeds 30% but is less than 180%, the error indication of variable ratio should be given. | |
