好串连不超过2只表,一般的4-20ma变送器能带的负载略大于500欧,而仪表的电流输入端大部分情况下并的是250欧电阻转换成1-5V。一般情况下可以串接几块电流表。其原因为：用4-20ma电流做远距离传送信号，在传送终端都接有500欧或250欧标准电阻，使4-20ma的电流信号在其电阻上产生与之成比例的2-10V或1-5V的电压信号，一般情况下这个电压值比电流源容许外电阻的大电压值要小5-10V以上，这多出的5-10V电压就是为传送导线内阻及串接电流表产生电压降用的，电流表的内阻都是很小的，只要传送导线内阻及串接的几块电流表的内阻产生的电压降之和<这多出的5-10V电压，就不会影响信号传送精度。
