目前使用的時間繼電器的時間范圍越來越寬,上限已達6000s以上,而一般電子計數器測時是達不到這個范圍的,所以時間繼電器測試儀就顯得尤為重要同時也會有寬廣的市場空間，二，時間繼電器測試儀的使用1，通電工作a)將電源插頭交流220V帶有接地線的電源插座中。 1.故障現象’K,V+Q:P,y;a;O.^電機不能起動，即使空載能起起動，轉速慢慢上升，有嗡嗡聲;電機冒煙，并伴有燒焦味。2.檢查結果拆下電機端蓋，可看到繞組端部有1/3或2/3的極相繞組或焦或變成深棕色。3.故障原因及處理方法(1)電動機供電回路熔絲回路不良或受機械損傷，致使某相熔絲熔斷。

②一般熱繼電器應置于手動復位的位置上，若需要自動復位時，可將復位螺釘沿順時針方向。③熱繼電器由于電動機過載動作后，若要再次啟動電動機，必須待熱元件冷卻后，才能使熱繼電器復位。一般復位時間是手動復位需要2min，自動復位需要5min。

低壓兩側無熔斷器，有的雖然已經裝上跌落式熔斷器和羊角，但其熔斷件多是采用鋁或銅絲代替，致使低壓短路或過載時，熔斷件無法正常熔斷而燒毀變壓器，(2)如果是用于農村的變壓器，由于農村照明線路較多，大多數又是采用單相供電。 圖㈡為用通電延時繼電器代替斷電延時繼電器的電路。把選擇開關SA置于1位時，繼電器KA得電吸合并自保持。當SA置于2位置時(或者利用繼電器的一組觸點)，通電延時繼電器KT2獲電，經過設定的延時時間，其延時斷開常閉觸頭斷電。
