When performing a powered leakage test on the PT250 / PT250+
With the power lead connected to the mains you select the “LKGE” button when ready to perform the “ILEAK” test – if not, the instrument will display “STOP” and not complete the test.
Note if the unit is not plugged into the mains it will automatically perform the battery powered Substitute Leakage test at 40Vac.
