虹吸雨量计的换纸方法有哪几种?

答案

参考答案:⑴无降水时,自记纸可连续使用8-10天,用加注1毫米水量的办法来抬高笔位,以免每日迹线重迭。

⑵有降水(自记迹线上升≥0.1毫米)时必须换纸。自记记录开始和终止的两端须作时间记号,可轻抬固定在浮子直杆上的自记笔根部,使笔尖在自记纸上划一短垂线;若记录开始或终止时有降水,则应用铅笔作时间记号。

⑶当自记纸上有降水记录,但换纸时无降水,则在换纸前应人工虹吸(注水入承水器产生虹吸),使笔尖回到自记纸“0”线位置。若换纸时正在降水,则不作人工虹吸。

⑷换纸时遇强降水,若自记纸尚有一部分可继续记录,则可等雨停或雨势转小后再换纸。如估计在短时间内雨不会停也不会转小,则可拨开笔尖,转动钟筒,在原自记纸的开始端(此处须无降水记录,或有降水自记迹线而不致重迭)对准时间,重新记录。待雨停或转小后,立即换纸。换下的自记纸应注明情况,分别在两天的迹线上标明日期,以免混淆。

⑸因雾、露、霜量使自记迹线上升≥0.1毫米时,不必换纸,但须在该自记纸换下后在背面注明。
