《计量技术》88年第3期在《磁电式仪表内阻的测定方法》一文中介绍了用1/2I_0的的方法从电阻箱直接读出内阻数值。本文将介绍另一种测定方法供参考。具体线路如图所示,先用一节电池与一拜A表头(我选用的是点温计7151型表头)
“Measurement Technology” 88 No. 3 in the “magnetic resistance meter measuring method” article describes the use of 1 / 2I_0 method from the resistance box directly read the internal resistance value. This article will introduce another measurement method for reference. The specific line as shown, first with a battery and a worship A header (I chose the point thermometer 7151 type header)
