使用注意事項 / Usage Precautions
1. 請確保設(shè)備接地良好，以保障操作人員安全及測量準(zhǔn)確性。 / Ensure the device is properly grounded for operator safety and measurement accuracy.
2. 連接被測儀表前，請確認(rèn)標(biāo)準(zhǔn)源的輸出處于關(guān)閉狀態(tài)或零輸出。 / Before connecting the device under test, confirm that the standard source s output is switched off or at zero output.
3. 嚴(yán)禁輸出過載，電流和電壓輸出不得超過額定最大值，以免損壞設(shè)備。 / Overloading is strictly prohibited. Do not exceed the rated maximum current and voltage output to prevent equipment damage.
4. 設(shè)備工作時會產(chǎn)生熱量，請確保周圍通風(fēng)良好，并留有足夠的散熱空間。 / The device generates heat during operation. Ensure adequate ventilation and sufficient space for heat dissipation around it.
5. 避免在潮濕、多塵、強電磁干擾的環(huán)境中使用。 / Avoid using the device in damp, dusty, or environments with strong electromagnetic interference.
6. 非專業(yè)人員請勿打開機箱進行維修或調(diào)整內(nèi)部參數(shù)。 / Do not open the chassis for maintenance or adjust internal parameters unless you are qualified personnel.
7. 長期不使用時，建議定期通電以保持內(nèi)部元件性能。 / If the device is not used for an extended period, it is recommended to power it on periodically to maintain the performance of internal components. |
