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 test, if the earth
resistance value is lower than 50V/I
∆n
the instrument displays for 5 seconds a
screen like this, then it passes to the
following measurement. Refer to § 4.15
for further details or information
regarding the negative outcome of the
test or anomalous situations
Measured value of
global earth
resistance
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 § 4.14
Measured value of
tripping time
Value of test current
10. At the end of the M  test, if the
detected resistance value is higher than
the minimum limit threshold (see § 4.5),
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 § 4.13
Measured value of
resistance
Value of test voltage
11. At the end of the AUTO test, if all tests
have a positive outcome, the instrument
emits a double sound to signal the
positive outcome and displays a screen
like this. To display partial results press
FUNC HOLD. The single test results
are dislayed cyclically by any new
pressure on this key
