Seaward Prime Test 200

[Mprwhu]

Good afternoon all,
Just got my seaward prime test 200 out of storage due to my other tester in for calibration/repair
Seaward recommended that insulation testing to be carried out at 250v but there is no option to change voltage on this machine, I now understand it’s been discontinued. As anyone else had this problem. In seawards on words this pat tester is unsuitable for pat testing IT equipment.

It will be fine at 500v. The only time 250v is really needed is if equipment incorporates surge suppression which can give false readings at 500v.
