The DNO voltage monitor will be calibrated so is correct, the maximum allowed voltage is 253V, this suggests the matt-e box is the problem, its set wrong. I thought the indra smart box did its own PEN testing and did not need a matt-e?

Edit : having seen @Mike Schooling 's comments I hope the DNO calibrate their instruments, I'd be troubled if they did not.
