1)在輸出電壓處

2)在輸出電壓和輸出電流處

測試條件：負載電阻大于2.5MΩ：應(yīng)避免在強磁場、酸堿環(huán)境下使用。

1)At the maximum output voltage

2)At the maximum output voltage and the maximum output current

Test conditions: load resistance is greater than 2.5MΩ : it should be avoided to use in strong magnetic field and acid-base environment.
