a terminal and n terminal are connected to heating cable
?  溫控器的探頭接到管路上，用鋁膠帶貼在管道上；
attaching the temperature probe to the surface of the pipe with aluminum adhesive tape
?  溫控器旋鈕調到您所需要維持的溫度上。
adjust the button to the number of practical temperature
 

5產品使用與維護 Application and Maintenance

? 打開接線盒蓋，擰下接線嘴，將進線和出線電纜穿過各自的接線口，上緊接線盒蓋。
Open the cover of the kit, screw off the connection terminal; insert the line through each terminal.
? 按接線腔內的接線圖接好電纜，擰緊接線嘴，上緊接線盒蓋。
Connect the lines as the diagram, tighten the terminal, and then tighten the cover with screws.
? 打開溫度調接盒外蓋，將溫度調整到所需控制溫度處，然后擰緊外蓋。
Adjust the temperature according to the practice need.
? 用卡箍將溫控器底座固定在適當位置，并將溫控探頭緊貼在被測試溫度的部位。
Install the temperature controller at the proper position; attach the probe closely to the vessel.
? 將引出線接到電源盒腔內，與腔內電伴熱帶相接，溫控器進線接入電源，檢查無誤后即可送電工作。
Connect the leading-out line with heating cable, connect the temperature controller to the power. Check the connection, and then turn on the power to operate.
? 溫控探頭只能水平或豎直安裝，否則會出現溫度不穩定現象。
Keep the probe vertical or horizontal, or temperature will be unstable.
? 接線盒如有變形，裂痕和損壞，應停止使用，更換新接線盒。
If the kit was deformed, chapped, please change a new one.
