A cheap ANALOGUE meter will provide the most reliable readings with this sort of test.

There is probably an "official" value for the resistance of a simulated load but I use a 270,000 ohm resistor ( 270KΩ ) ½ Watt between metal and earth for the initial check. This is "safe" as if there is a short ( Live to the metal ) then the resulting 230 volts across 270KΩ is less than 0.2 watt so the resistor doesn't explode.

Polarity in the socket is ok, polarity in the lighting unit is ok. What level of voltage is considered acceptable? 11.4 V will not kill you but can some one continue using this unit?^and if the lamp holder is the correct polarity check the polarity of the socket /supply.
