Note
1. For full rating output, the line input range is +10%, -5%.
2. 40 amp for TUV 120 seconds, 40.1 – 45amp continue is 60 seconds.
The maximum test resistance range is with offset value 510mΩ, at 8amp
output.
3. For getting the optimal accuracy, please use the 4-wire type for measuring.
It is no need to do offset again. When offset value is lower than 10mΩ, it is
over test specification. By using offset can increase 5mΩ maximum
specifications error.
