技术如下"

一．仪器外观及工作正常性检查：正常。

二． f = 50 Hz

1．电流示值误差:

     量  程              指 示 值（A）           实 际 值 (A)         
   3A - 30A                 5.0                     5.02
                           10.0                    10.01                                                         
                           15.0                    15.01
                           20.0                    20.01
25.0         25.02
                           30.0                    30.01

2.电阻示值误差（25A下测试）
    
   指 示 值（mΩ）            实 际 值（mΩ）
                         10                         10.2
                         99                         99.1
                         198                        198.2
                         502                        502.3
3.电阻示值误差（10A下测试）

                    指 示 值（mΩ）           实 际 值（mΩ）
                          10                        10.
                          99                        99.2
                          198                       198.3
                          502                       502.3
