was detected (depending on the
selected voltage see following Note
table, the instrument emits a double
beep at the end of the test indicating
the positive outcome of the test and
displays a screen similar to the screen
alongside.

In case a test is performed at a voltage
lower than the set rated voltage, at
the end of the test the instrument emits
a long beep and displays a screen
similar to the screen alongside.

ATTENTION: the test of resistance R
ISO
was
performed at a voltage value lower than the set
rated voltage. Low insulation case. This case
occurs under low insulation conditions or in the
presence of capacitance on the installation.
SAVE SAVING: The test can be stored pressing the SAVE key twice (refer to

If the terminal voltage is greater than
30V, the instrument does not perform
the test, displays the screen alongside
for 5 seconds after which, it shows the
default screen relative to the R

test
under selected mode.
ATTENTION: the
test was not
carried out.
Check that the
circuit is not
energized.
SAVE THIS RESULT CANNOT BE SAVED.
