絕緣電阻率測試儀概述
BEST- 121型高絕緣電阻測量儀用于測量絕緣材料、電工產(chǎn)品、各種元器件的絕緣電阻;與恒溫水浴配套后,還能測量不同溫度下的塑料電線電纜(無屏蔽層)的絕緣電阻,該儀器具有測量精度高、性能穩(wěn)定、操作簡單、輸入端高壓短路等優(yōu)點,儀器的zui高量程 1018Ω電阻值(測試電壓為 1000V)。 本儀表貫徹 Q/TPGG 7-2008 高絕緣電阻測量儀企業(yè)標準。
①直流高壓電流輸出 10,50,100,500,1000V 五檔
②根據(jù)試樣的電阻值及直流高壓值選擇合適的量程倍率。
③高輸入阻抗直流放大器(輸入阻抗>1015Ω)

絕緣電阻率測試儀安全注意事項
4.1 使用前務必詳閱此說明書,并遵照指示步驟,依次操作。
4.2 請勿使用非原廠提供之附件,以免發(fā)生危險。
4.3 進行測試時,本儀器測量端高壓輸出端上有直流高壓輸出,嚴禁人體接觸 ,以免觸電。
4.4 為避免測試棒本身絕緣泄漏造成誤差,接儀器測量端輸入的測試棒應盡可 能懸空,不與外界物體相碰。
4.5 當被測物絕緣電阻值高,且測量出現(xiàn)指針不穩(wěn)現(xiàn)象時,可將儀器測量線屏 蔽端夾子接上。 例如:對電纜測纜芯與纜殼的絕緣時,除將被測物兩 端分 別接于輸入端與高壓 端,再將電纜殼 ,芯之間的內層絕緣物接儀器 “G”,以消 除因 表面漏電而 引起的測量誤差。也可用加屏蔽盒的方法, 即將被測物置于金屬屏蔽盒內,接上測量線。
絕緣電阻率測試儀同時測出電阻兩端的電壓V和流過電阻的電流I,通過內部的大規(guī)模集成電路完成電壓除以電流的計算,然后把所得到的結果經(jīng)過A/D轉換后以數(shù)字顯示出電阻值,即便是電阻兩端的電壓V和流過電阻的電流I是同時變化,其顯示的電阻值不象普通高阻計那樣因被測電壓V的變化或電流I的變化而變,所以, 即使測量電壓、被測量電阻、電源電壓等發(fā)生變化對其結果影響不大,其測量精度很高。從理論上講其誤差可以做到零。而實際誤差可以做到千分之幾或萬分之幾。
絕緣電阻率測試儀注意事項
★★★★★★★★★★★★★
儀器使用前請仔細閱讀以下內容,否則將造成儀器損壞或電擊情況。
1. ★檢查儀器后面板電壓量程是否置于10V檔,電流電阻量程是否置于104檔。
2. ★接通電源調零,(注意此時主機不得與屏蔽箱線路連接)在“Rx”兩端開路的情況下,調零使電流表的顯示為0000。然后關機。
3. ★將待測試樣平鋪在不保護電極正中央,然后用保護電極壓住樣品,再插入被保護電極(不保護電極、保護電極、被保護電極應同軸且確認電極之間無短路)。
4. ★測體積電阻時測試按鈕撥到Rv邊,測表面電阻時測試按鈕撥到Rs邊,
5. ★接好測試線,將測試線將主機與屏蔽箱連接好。量程置于104檔,打開主機后面板電源開關按鈕。從儀器后面板調電壓按鈕到所要求的測量電壓。(比如:GBT 1692-2008 硫化橡膠 絕緣電阻率的測定 標準中注明要求在500V電壓進行測定,那么電壓就要升到500V)
6. ★電流電阻量程按鈕從低檔位逐漸撥高檔,每撥一次停留1-2秒觀察顯示數(shù)字,當被測電阻大于儀器測量量程時,電阻表顯示“1”,此時應繼續(xù)將儀器撥到量程更高的位置。測量儀器有顯示值時應停下,在1min的電化時間后測量電阻,當前的數(shù)字乘以檔次即是被測電阻。
7. ★測試完畢先將量程撥至(104)檔,然后將測量電壓撥至10V檔,zui后將測試按鈕撥到中央位置后關閉電源。然后進行下一次測試。
8. ★應在“Rx”兩端開路時調零,一般一次調零后在測試過程中不需再調零。
9. ★禁止將“RX”兩端短路,以免微電流放大器受大電流沖擊。
10. ★不得在測試過程中不要隨意改動測量電壓。
11. ★測量時從低次檔逐漸撥往高次檔。
12. ★接通電源后,手指不能觸及高壓線的金屬部分。
13. ★不得測試過程中不能觸摸微電流測試端。
14. ★在測量高阻時,應采用屏蔽盒將被測物體屏蔽。
15. ★嚴禁在試測過程隨意改變電壓量程及在通電過程中打開主機。
16. ★嚴禁電流電阻量程未在104檔及電壓在10V檔,更換試樣。

絕緣電阻率測試儀使用方法
6.1接好電源線
確保電源為220VAC/50Hz
6.2接通電源
將電流電阻量程置于 104 檔,電壓量程置于10V,然后開機。
6.3調零
在“Rx”兩端開路的情況下,調零使電流表的顯示為0000 .注意:在“Rx”兩端不開路,如接在電阻箱或被測量物體上時調零后測量會產(chǎn)生很大的誤差。一般一次調零后在測試過程中不需再調零。 完畢后關機。
6.4連接線路
接好測試線,將測試線將主機與屏蔽箱連接好,測體積電阻時測試按鈕撥到Rv邊,測表面電阻時測試按鈕撥到Rs邊。然后開機。
6.5選擇合適的測量電壓
★電壓選擇開關在后面板,注意,在測試過程中不要隨意改動測量電壓,可能因電壓的過高或電流過大損壞被測試器件或測試儀器;
6.6測試
測量時從低檔位逐漸拔往高檔,每撥一次稍停留1~2秒以使觀察顯示數(shù)字, 當被測電阻大于儀器測量量程時,電阻表顯示“1”,此時應繼續(xù)將儀器撥到量程更高的位置,當測量儀器有顯示值時應停下,當前的數(shù)字乘以檔次即是被測電阻值。當有顯示數(shù)字時不要再往更高次檔撥,否測儀器會過量程,機內保護電路開始工作,儀器測量準確度會下降。
6.7 測試完畢將電阻電流量程拔至“104 ”檔,電壓量程調至10V后關閉電源
★每測量一次均應將量程開關撥回到104“調零”檔的量程位置以免開機或測量端短路時而損壞儀器。
6.8 測量電流及1015Ω以上超高電阻的測量應用測量電流后用歐姆定律以電壓除以電流計算電阻的方法,詳見8.5節(jié)內容。
6.9 體積電阻和表面電阻轉換
★在測試過程中,使用屏蔽箱在進行體積電阻和表面電阻轉換時,必須把電源關閉后進行檔位轉換,否則會導致電壓沖擊到主機無法顯示或損壞。

Security considerations
4.1 be sure to read the manual before use and follow the instructions step, operating in turn.
4.2 do not use the original factory to provide the attachment, thank you for your cooperation.
4.3 during the test, the instrument measuring the dc high voltage output high voltage output, it is strictly prohibited to human exposure, so as to avoid electric shock.
4.4 to avoid test bar insulation leakage error caused by itself, by instrument measuring the input can be hung up test bar, no object collision with the outside world.
Analyte 4.5 when a high insulation resistance, and measure the instability phenomenon appear Pointers, line screen can be measured All the clip connected. For example: the insulation of the cable and cable to cable measured shell, in addition to the analyte to the two end points Don't pick up the input and the high pressure side, and then to a shell, the cable core between inner insulation instruments \"G\", to eliminate the error of measurement caused by surface leakage. Method can also be used with shielding box, is about to be tested on the metal shielding box, measuring line.
At the ends of the resistance is measured at the same time current through the resistor voltage V and I, through the internal voltage divided by the current calculation of large scale integrated circuit is complete, then put the results after A/D conversion to digital shows resistance, even at the ends of the resistance current through the resistor voltage V and I change at the same time, the display of the resistance is not like ordinary high resistance meter by measuring the change of the V voltage or current I change and change, so, even if the measured voltage, by measuring the resistance and voltage change has A little influence on the results, the measuring precision is high. In theory it can achieve zero error. The actual error can be done a few parts per thousand or very few.
