• 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
PE
measurement
and so no tick or cross is displayed.

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.
