儀器正確連接后，接通電源到額定電壓，此時(shí)綠色指示燈亮，儀器即處于監(jiān)測(cè)狀態(tài)；當(dāng)絕緣電阻值低于設(shè)定值時(shí)發(fā)出一報(bào)警信號(hào)，此時(shí)報(bào)警紅燈點(diǎn)亮，報(bào)警輸出端發(fā)生變化，常閉端轉(zhuǎn)換成常開，常開端轉(zhuǎn)換成常閉。After the instrument is correctly connected, power on to the rated voltage, then the green indicator light is on, the instrument is in the monitoring state; When the insulation resistance value is lower than the set value, an alarm signal is issued. At this time, the alarm red light is on, and the alarm output end changes. The normally closed end is converted to normally open, and the normally started is converted to normally closed.

儀器在工作時(shí)報(bào)警設(shè)定開關(guān)應(yīng)設(shè)置在所選定的報(bào)警值位置，報(bào)警值有十檔，分別為：0.01MΩ、0.03MΩ、0.06MΩ、0.1MΩ、0.2MΩ、0.5MΩ、1MΩ、（1.5MΩ、2MΩ、5MΩ）。When the instrument is in operation, the alarm setting switch should be set at the selected alarm value. The alarm value has ten levels, which are respectively:0.01MΩ、0.03MΩ、0.06MΩ、0.1MΩ、0.2MΩ、0.5MΩ、1MΩ、（（1.5MΩ、2MΩ、5MΩ）。

如需判別儀器工作是否正常時(shí)可進(jìn)行自檢，將儀器后面開關(guān)設(shè)置在自檢檔位，儀器即進(jìn)行自檢，此時(shí)報(bào)警紅燈點(diǎn)亮，報(bào)警輸出端發(fā)生變化，常閉端轉(zhuǎn)換成常開，常開端轉(zhuǎn)換成常閉；自檢完畢后必須將儀器恢復(fù)到正常測(cè)量檔位上。for identifying whether instruments work normally when the self-checking, can be put behind the instrument switch Settings in self-inspection gear, instrument is introspected, warning red light light up, at this time change alarm output end, into a normally open normally closed end, often beginning into a normally closed; After the self-test, the instrument must be restored to the normal measuring gear.

接岸電時(shí)，由于岸電系統(tǒng)為接地系統(tǒng)，儀器會(huì)發(fā)出誤報(bào)警，此時(shí)可將開關(guān)調(diào)整到“岸電”檔；但輸出常開、常閉觸點(diǎn)不會(huì)發(fā)生轉(zhuǎn)換動(dòng)作，無報(bào)警輸出。When answering ? shore power, due to shore power system for the grounding system, instruments have a false alarm, the switch can be adjusted to "shore power"; But the output normally open and normally closed contacts will not have conversion action, no alarm output.

外接指示表頭（如需要時(shí)）即11和12端子。11和12號(hào)端子輸出信號(hào)為0-1mA電流信號(hào)，用于驅(qū)動(dòng)外接指示儀表；而該輸出電流信號(hào)與絕緣監(jiān)測(cè)儀相對(duì)應(yīng)關(guān)系，顯示儀表標(biāo)牌顯示∞-0.2-0MΩ（0-1mA）。external instructions header (if needed) 11 and 12 terminals. The output signals of terminals 11 and 12 are 0-1mA current signals, which are used to drive the external indicator instrument; And the output current signal and corresponding insulation monitor, display instrument panels show up - 0.2-0MΩ (0-1 ma).

儀器可用在各種船舶配電板、礦井、醫(yī)療、空調(diào)、充電樁、電站等各種IT配電電網(wǎng)系統(tǒng)上面使用。The instrument can be used in all kinds of SHIP switchboard, mine, medical treatment, air conditioning, charging pile, power station and other IT power distribution system.
