The message "Measuring" on the display means that the instrument is
measuring. During this phase never disconnect test leads.
7. During measurements, at the end of each test, the partial values are displayed for 5
seconds, then the instrument passes to the following test
8.
At the end of the Ra
resistance value is lower than 50V/I
the instrument displays for 5 seconds a
screen like this, then it passes to the
following measurement.

9. At the end of the test, if the detected
tripping time is lower than the maximum
admittable limit, the instrument displays
for 5 seconds a screen like this, then it
passes to the following screen. For
further details or information regarding
the negative outcome of the test or
anomalous situations refer to paragraph

10.
At the end of the MΩ test, if the
detected resistance value is higher than
0.5MΩ, the instrument displays for 5
seconds a screen like this, then it
passes to the following screen. For
further details or information regarding
the negative outcome of the test or
anomalous situations refer to paragraph
