六、利用注重事變 :
高阻丈量必然要嚴酷按利用方式步聚停止，不然有能夠形成儀器*破壞或電人。 
1 應在“Rx”兩頭開路時調零（主機開機）
  如接在電阻箱或被丈量物體上時調零后丈量會產生很大的偏差。普通一次調零后在測試進程中不需再調零，但轉變丈量電壓后能夠要從頭調零。 
2 制止將“Rx”兩頭短路，以避免微電流縮小器受大電流打擊
3 在測試進程中不要隨便修改丈量電壓， 
  隨便修改丈量電壓能夠因電壓的太高或電流過大破壞被測試器件或測試儀器，并且有的材料長短線性的，即電壓與電流是不合適歐姆定律，有轉變電壓時因為電流不是線性變更，以是丈量的電阻也會變更。 
4 丈量時從低次檔逐步拔往高次檔 
  每撥一次稍逗留1～2秒以便察看顯現數字，當有顯現值時應停下，記實以后的數字便是被測電阻值。若顯現“1”時，表現欠量程應往高次檔拔。直到有顯現數字時為止。當有顯現數字時不能再往高次檔撥，不然有能夠破壞儀器(機內有過電流掩護電路)。除104 Ω檔以外，當顯現低于1.99，表現適量程應換高檔! 
5 大局部絕緣材料，出格是防靜電材料的電阻值在加電壓后會有必然變更而引發數字變更 
  因為本儀器的辯白率很高，因此會引發顯現值的開端幾位數也變更，這不是儀器自身的題目，而是被丈量工具的導機電理龐雜而使得阻值有些變更。在這類環境下常常取2位有用數就夠了。 
6 接通電源后，手指不能涉及高壓線的金屬局部 
    本儀表有二連根線:高壓線(紅)和微電流測試線。在利用時要注重高壓線，開機先人不能涉及高壓線，以避免電人或麻手。 
7 測試進程中不能觸摸微電流測試端 
  微電流測試端zui怕遭到大電流某人體感到電壓及靜電的打擊。以是在開機后和測試進程中不能與微電流測試端打仗，以避免破壞儀表。 
8 在丈量高阻時，應接納屏障盒將被測物體屏障. 
  在丈量大于1010 Ω以上時，為避免外界攪擾面而引發讀數不穩。 
9 每次丈量完時應將量程開關撥回“104 ”檔再停止下次測試
  在丈量時應逐步將量程開關撥到高阻檔，丈量完時應將電流電阻量程、電壓量程開關撥回高檔。以 確保下次開機時量程開關處在低阻量程檔。
