中文介紹
瑞得電子經(jīng)緯儀DT-02是一款性能可靠的測量儀器，采用絕對編碼測角方式，結(jié)構(gòu)簡單，開機無需初始化，關(guān)機后再開機仍可顯示原來的測角數(shù)據(jù)。其望遠鏡成像為正像，放大倍率為30倍，有效孔徑45mm，分辨率3″，視場角1°30′，最小視距1.4m，視距乘常數(shù)100，視距加常數(shù)0，筒長157mm。測角精度為2″，最小顯示讀數(shù)1″/5″可選。長水準器精度為30″/2mm，圓水準器精度為8′/2mm。儀器尺寸為165×157×318mm，重量4.3kg，使用環(huán)境溫度范圍為-20℃～+45℃，配備可充電鎳氫電池/AA電池，連續(xù)工作時間可達10小時。此外，該儀器還具備良好的防水防塵性能。
English Introduction
The Ruida DT-02 electronic theodolite is a reliable measuring instrument. It adopts the absolute encoding angle measurement method. The structure is simple. There is no need to initialize when starting up. After shutdown, it can still display the previous angle measurement data when turned on again. The telescope of this theodolite provides erect images, with a magnification of 30 times, an effective aperture of 45mm, a resolution of 3″, a field of view of 1°30′, a minimum viewing distance of 1.4m, a stadia constant of 100, a stadia additive constant of 0, and a tube length of 157mm. The angle measurement accuracy is 2″, and the minimum display reading can be selected as 1″ or 5″. The long level vial has a precision of 30″/2mm, and the circular level vial has a precision of 8′/2mm. The instrument measures 165×157×318mm in size and weighs 4.3kg. It can operate within an ambient temperature range of -20℃ to +45℃ and is equipped with rechargeable nickel-hydrogen batteries/AA batteries, which can support continuous operation for up to 10 hours. Moreover, the theodolite features good waterproof and dustproof performance.
