Loop test with fluke three wire ??

[sidekick]

Can anyone shed any light. Just done loop test with fluke L-N-E setting L-PE. Reading was 8.66 ohms. Have reported high reading to DNO who sent engineer out. He then tested two wire L-E and read 0.13 ohms. this iss not the first time with high reading on my tester and has recently been calibrated. Am I doing something wrong ??

Ze readings are done with 2 wire connections. 3 wire is for no-trip.

but on the fluke if you don't use three wire it shows error and as well as being in the instructions, most of the time it is not a problem. This is the second time DNO have disputed the reading though
