当前,国内许多工业、科研领域已逐步用数字式仪器仪表取代老式指针式仪器仪表。通常,廉价的数字仪器仪表一般没有配接数据打印输出接口。在某些要求自动定时或手动打印数据的场合,改造工作一般较为繁琐且造价较高。本文介绍一种用打印计算器构成的简易数据记录接口电路,该电路能可靠地完成由7106系列A/D 转换器或其它3(1/2)位数字显示仪器仪表 At present, many industrial and research fields in China have gradually replaced the old-fashioned pointer instruments with digital instruments. Generally, cheap digital instruments generally do not have a data printout interface. In some cases where automatic timing or manual printing of data is required, the remodeling work is generally cumbersome and costly. This article describes a printer with a simple data recording interface circuit composed of the circuit can be reliably completed by the 7106 Series A / D converter or other 3 (1/2) digital display instrumentation
