本計(jì)米器是根據(jù)用戶需要設(shè)計(jì)而成用于測(cè)量長(zhǎng)度和各種機(jī)械傳動(dòng)的記錄器，一般用于紡織、印染、塑料薄膜，人造皮革等放量長(zhǎng)度的記錄。
　　本器為五位數(shù)，計(jì)數(shù)范圍1-99999，當(dāng)記錄長(zhǎng)度為1m時(shí)（或1碼時(shí)）滾動(dòng)輪轉(zhuǎn)三圈，計(jì)數(shù)器數(shù)字顯示1，依次類(lèi)推，逢十進(jìn)位，但不能逆向計(jì)數(shù)傳動(dòng)比為：1：3，最高計(jì)數(shù)速度：200次/分。
　　本器裝有復(fù)零機(jī)構(gòu)，復(fù)零采用旋轉(zhuǎn)式，旋轉(zhuǎn)一周號(hào)碼全為"0"字，然后作第二階段計(jì)數(shù)，使用極為方便。
　　本器跳號(hào)靈活，計(jì)數(shù)正確，號(hào)碼顯示清晰，工作環(huán)境溫度在-20℃～＋60℃，仍能保持正常計(jì)數(shù)。

　　Designed according to uses'requirements,this counter is a recorder of ength and various mechanical transmissions. Commonly it is used to record the length range in the professions of Textile, Printing and Dyeing, Membrane, ang Man-made Leather.
　　 This counter is five-digital with counting range of 1-99999. When the recorded length is one meter or one yard, the scrolling wheel turns three circles, indicating "1".Thereby the counter dots and carries one. But it can't count widdershins.The transmission rate is 1:3.The highest counting speed is 200 times/min.
　　 This counter is staffed with a zero reset facility. The facility adopts revolving style. If it whirls one circle, the figure is turned to zero. Then the counter stars counting for the second stage.Therdfore it is very convenient to use.
　　 Changing the digit flexibly and indicating the figures clearly, this counter records the numbers precisely. It can operate normally even if the temperature of the working environment shifts from-20℃～＋60℃.
