把測量儀旋轉 180 度,但是不可改變測量儀的高
度。讓儀器找平。把另外一道側面激光投射在牆上
的激光中心點打上記號 (點 II。盡量讓點 II
在點 I 的正上方或正下方。
牆上點 I 和點 II 的差距 d便是測量儀在橫軸的實際
高度誤差。
測量的距離是 2 x 20 米 = 40 米。而最大的許可誤
差為 :
40 米 x ±0.3 毫米 / = ±12 毫米。
I 和點 II 的差距 d 不可以超過 12 毫米。
檢查縱軸的水平水準精度
檢查時要找兩道距離 20 米的牆 A 和牆 B,地板得結實
平坦而且測量距離上不可以有障礙物。
使用支撐或三腳架把測量儀固定在靠近牆 A 的地
方,您也可以把儀器放置在結實平坦的底墊上。開
動測量儀。
把和測量儀的縱軸平行的水平激光投射在靠近儀器
的牆 A 上。讓儀器找平。把投射在牆上的激光中心
點打上記號 (點 I)。
把測量儀旋轉 180 度,讓儀器找平,並在投射于牆
B 上的激光中心點打上記號 (點 II)。
把儀器移近牆 B(無須旋轉測量儀)開動測量儀,
並讓儀器找平。
調整測量儀的高度 (借助三腳架,必要時得使用墊
塊),讓激光中心點準確地投射在牆 B 的點 II 上。
把測量儀旋轉 180 度,但是不可改變測量儀的高
度。讓測量儀找平,並在投射于牆 A 上的激光中心
點上做記號 (點 III。盡量讓點 III 位在點 I 的正
上方或正下方。
牆A上I 和點 III 的差距d便是測量儀在縱軸的實
際高度誤差。
測量的距離是 2 x 20 米 = 40 米。而最大的許可誤
差為 :
40 米 x ±0.3 毫米 / 米 = ±12 毫米。
I 和點 III 的差距 d 不可以超過 12 毫米。
有關操作方式的指點
記號只能打在激光的中心點上。 激光點的大小會隨
著距離的遠近而改變。
使用支撐固定
把支撐上的固定螺絲 9 緊緊地擰入測量儀器上的 1/4
英寸的三腳架接頭 6 中,以便把測量儀器固定在支撐
8 上。稍微擰松螺絲 9 便可以轉動固定在支撐上的測
量儀器。
朝著側面或朝下擰轉固定在支撐 8 上的測量儀器,
便可以看見儀器下端的垂直激光。
利用水平激光轉載高度時,必須旋轉固定在支撐 8
上的測量儀器。
