    Actually reading through the post again I guess it may be a three phase supply, because Lyle said the result recorded five years ago was recorded as 1.58X2 so they may be a L-L readings rather than L-N.

    But I am quite confident that the testing procedures are comparable. 

    Making comparative readings between test meters is one of the three methods given in the EAS specification for ensuring the ongoing accuracy of test meters, so Lyle is complying with the EAS requirements by taking these readings with three meters and comparing the results, but I'm not sure what he is going to write in the test meter log books.
