PrimeTest 250

Operating Instructions

• Otherwise, the PrimeTest 250

will proceed

with the R

measurement, reverse the test

current and then repeat the measurement. The

highest measured value that occurred during

the two tests is displayed for approximately 2s.

Note: There is no factory programmed test

limit for the 3 phase R

measurement

and so no tick or cross is displayed.

• The PrimeTest 250

will then display the current

ﬂ owing in the protective conductor of the 3

phase supply.

• The 3-Phase leakage test will run for 30

seconds but can be stopped earlier by pressing

the 3-Phase button.

Note: If the 3-Phase key is pressed while no

adaptor is connected to the PrimeTest

250

then a warning message PLUG IN

3 PH ADPTR will be displayed.
