求翻译：卷芯表面不得有粉尘，电压选择符合工艺要求、正负极之间不短路(电压表报警). 放电按钮置于off状态是什么意思？

Volume core surface may not have dust, voltage selection to meet the technical requirements, not short-circuit between the positive and negative (voltmeter alarm). Discharge button to the off state

Volume-surface shall be consistent with dust, the voltage selection process requirements, both positive and negative pole circuit (voltage between Table alarm) discharge button . in the off state

The volume core surface must not have the dust, the voltage choice conforms to the technological requirement positively and negatively, extremely does not short-circuit (voltmeter to report to the police). Discharges the button to put in the off condition

Volume conductor surface without dust, select meet the process requirements, not between positive and negative voltage short circuit (voltage meter and alarm). Discharge status button on off
