測量距離
透過測量長度時的起始點來瞄準測量儀
器。
寫下十字交叉線段的上線和下線在水準尺
上所在位置的刻度值。 將十字交叉線段的
上線和下線的高度差值乘 100 以上所得
的值便是從測量儀器到水準尺的距離。
圖上測得的距離是 :
(1,347 –1,042 ) x 100 = 30,5 .
角度測量
透過測量角度時的起始點來瞄準測量儀器。
把測量儀器對準點 A 轉動水平刻度盤 10 讓刻度 0
準水平刻度盤的讀取記號 9 接著把測量儀器朝向點 B
此時便可以記下水平刻度盤的讀取記號 9 下的刻度。
GOL 20 D/GOL 26 D/GOL 32 D: 範例測量所得的角度
: 45 °
GOL 20 G/GOL 26 G/GOL 32 G: 範例測量所得的角度
: 45 新度
檢查儀器的測量準確度
操作儀器之前或經過長時間的運輸之後,都必須檢查測
量儀器的找平精度和顯示精度。
檢查圓水準儀
使用地腳螺栓 12 校准測量工具。 調整螺栓讓氣泡位在
圓水准儀 7 的中央。
將望遠鏡旋轉 180°,如果氣泡離開了圓水准儀 7 的中央
位置,便須再度校准圓水准儀。
再度校准圓水准儀
把圓水准儀 7 的氣泡移動到圓水准儀的外
圍和中心點之間。此時必須擰轉地腳螺栓
12
使用內六角扳手 17 擰轉矯正螺釘 11,讓氣泡進入圓水
准儀的中央位置。
將望遠鏡旋轉 180° 來檢查圓水准儀。需要的話要重覆
調校過程或者接洽博世的顧客服務處。
檢查脹縮件
做好測量儀器的校準和聚焦工作後,先尋找一個參考點
並測量該點的高度。 接著按下脹縮件的鎖定鈕 8 並隨即
放開它。重新測量參考點的高度。
如果兩次的高度測量結果不一致, 便必須把測量儀器交
給博世顧客服務處修理。
檢查十字交叉線段
檢查時必須找一段 30 公尺長的測量距離。 把測量儀器
放在中央。在測量距離的兩端分別放置水准尺 A 和水准
B
做好測量儀器的校准和聚焦工作後,再先後讀取兩個水
准尺上的高度。 計算出差值 d;即 a
1
( 水准尺 A 上的高
) b
1
( 水准尺 B 上的高度 ) 的差距。
例子 :
a
1
=1,937
b
1
=1,689
a
1
b
1
=1,937–1,689 =0,248= d
把測量儀器放置在距離水准尺 A 1 米處。 做好測量儀
器的校准和聚焦工作後,再讀取高度值 a
2
( 水准尺 A
的高度 )
把先前計算所得的 d 值從測量所得的高度值 a
2
中減除,
以求得高度 b
2
( 水准尺 B 上的高度 ) 的額定值。
測量高度 b
2
(在水準尺 B 上測量)。測量值和計算所
得的設定值的差異如果超過 6 毫米 (GOL 20 D/G),
3 毫米 (GOL 26 D/G) 2 毫米 (GOL 32 D/G) 則要再度
校準十字交叉線段。
