   (5%-149%)In     (In =1A)
(2) Voltage:(5%-149%)Un        (Un =100V, 100V/ √3V)
          (5%-200%)Un        (Un =100V/3)
2.3 Work Load:
(1) Current: TO to TX<0.12Ω        cosΦ=1.0
(2) Voltage: a to x<0.25VA        (100V)
2.4 Reversed Polarity Indication
Take action according to the Polar Instructions when the current is larger than 5% of the rated value and the error is larger than 180%.
Note: If no indication comes up when the current is larger than 10% of the rated value, bug exists. On such occasions, be sure not to increase the current in case to burn the machine.
2.5 Indication of False Transformation Ratio
There should be an indication of false transformation ratio when the current is larger than 5% of the rated value and the error is between 30% and 180%.
2.6 Insulation and High Voltage Test
 Terminal TX is connected with terminal()
 The power socket can bear a voltage of 1.5kV with respect to the outer shell for 1 min.
