line-height: inherit; font-family: 微軟雅黑, "Microsoft YaHei"; vertical-align: baseline; box-sizing: border-box;">　直流電阻測試儀是側(cè)向變壓器繞組以及大功率電感設(shè)備直流電阻的理想設(shè)備。在實際應(yīng)用中，也有用戶反映設(shè)備在使用過程中會出現(xiàn)故障。下面為大家詳細(xì)講解直流電阻測試儀廠出現(xiàn)的三個問題及解決方法。</span></p><p style="margin: 18px 0px 0px; padding: 0px; border: 0px; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-stretch: inherit; font-size: 15px; line-height: 2em; font-family: Arial, "Microsoft YaHei", 黑體, sans-serif, Tahoma; vertical-align: baseline; box-sizing: border-box; text-align: justify;"><span style="margin: 0px; padding: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: 微軟雅黑, "Microsoft YaHei"; vertical-align: baseline; box-sizing: border-box;">　　一、直流電阻測試儀一開機就燒保險。</span></p><p style="margin: 18px 0px 0px; padding: 0px; border: 0px; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-stretch: inherit; font-size: 15px; line-height: 2em; font-family: Arial, "Microsoft YaHei", 黑體, sans-serif, Tahoma; vertical-align: baseline; box-sizing: border-box; text-align: justify;"><span style="margin: 0px; padding: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: 微軟雅黑, "Microsoft YaHei"; vertical-align: baseline; box-sizing: border-box;">　　開機燒保險情況需要分兩種情況：5A~10A的直阻儀出現(xiàn)這種情況，一般來說是高壓將內(nèi)置變壓器燒壞，致使儀器無法正常使用;電流在20A以上的直阻儀出現(xiàn)這種情況，通常是開關(guān)電源有問題。出現(xiàn)燒保險的情況，只需及時更換變壓器或者開關(guān)電源即可正常使用。在進(jìn)行設(shè)備維修時，必須有專業(yè)工程師對設(shè)備進(jìn)行拆卸，如果現(xiàn)場不具備維修條件，則需返廠維修。</span></p><p style="margin: 18px 0px 0px; padding: 0px; border: 0px; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-stretch: inherit; font-size: 15px; line-height: 2em; font-family: Arial, "Microsoft YaHei", 黑體, sans-serif, Tahoma; vertical-align: baseline; box-sizing: border-box; text-align: justify;"><span style="margin: 0px; padding: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: 微軟雅黑, "Microsoft YaHei"; vertical-align: baseline; box-sizing: border-box;">　　二、使用直流電阻測試儀，但是測不出來電阻值。</span></p><p style="margin: 18px 0px 0px; padding: 0px; border: 0px; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-stretch: inherit; font-size: 15px; line-height: 2em; font-family: Arial, "Microsoft YaHei", 黑體, sans-serif, Tahoma; vertical-align: baseline; box-sizing: border-box; text-align: justify;"><span style="margin: 0px; padding: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: 微軟雅黑, "Microsoft YaHei"; vertical-align: baseline; box-sizing: border-box;">　　出現(xiàn)測不出值的現(xiàn)象一般有兩種原因：1.開關(guān)電源壞了，無電流輸出;2.設(shè)定值超出設(shè)備量程，程序無法識別指令。如果是電源損壞，更換電源即可。如果是超量程，重新啟動儀器，選擇范圍內(nèi)的電阻或電流進(jìn)行測量即可。</span></p><p style="margin: 18px 0px 0px; padding: 0px; border: 0px; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-stretch: inherit; font-size: 15px; line-height: 2em; font-family: Arial, "Microsoft YaHei", 黑體,

font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: 微軟雅黑, "Microsoft YaHei"; vertical-align: baseline; box-sizing: border-box;">　　三、直流電阻測試儀試驗過程中出現(xiàn)花屏。</span></p><p style="margin: 18px 0px 0px; padding: 0px; border: 0px; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-stretch: inherit; font-size: 15px; line-height: 2em; font-family: Arial, "Microsoft YaHei", 黑體, sans-serif, Tahoma; vertical-align: baseline; box-sizing: border-box; text-align: justify;"><span style="margin: 0px; padding: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: 微軟雅黑, "Microsoft YaHei"; vertical-align: baseline; box-sizing: border-box;">　　直阻儀出現(xiàn)花屏極有可能是內(nèi)部排線接觸不良。關(guān)機檢查排線是否松動，加固排線即可解決問題。還有一種可能是由于電磁干擾導(dǎo)致屏幕顯示異常。如果是這個原因，只需聯(lián)系廠家，增加一個濾波電容即可。除了設(shè)備本身的質(zhì)量問題之外，不合理的操作方法和貯存方式也會造成設(shè)備損壞。在使用過程中，不能用高溫東西接觸LED屏，測試前需檢查輸入接口夾具是否正常。另外，保持設(shè)備干燥清潔也是延長使用壽命的有效法方法。另外，對于檢測設(shè)備測量的特殊要求，好每年對設(shè)備進(jìn)行校正一次，確保測量值的準(zhǔn)確性和穩(wěn)定性。</span></p><p style="margin: 18px 0px 0px; padding: 0px; border: 0px; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-stretch: inherit; font-size: 15px; line-height: 2em; font-family: Arial,
