for at least one second, the instrument performs the
measurement
CAUTION
The message “

” on the display means that the instrument is
measuring. During this phase never disconnect test leads.
8.
Measured value of
global earth
resistance
The symbol HOLD
remains on until a
new measurement
can be taken
At the end of the test, if the earth
resistance value is lower than 1999
Ω
,
the instrument emits a double sound
and displays a screen like this reporting
the value of the measured global earth
resistance and the current at which the
measurement has been performed
Current used during
the measurement
9.
Measured value of
global earth
resistance
The symbol HOLD
remains on until a
new measurement
can be taken
If a test current of 100mA has been
selected and the earth resistance value
is lower than 1999
Ω
, by pressing
FUNC
you will display alternatively the values
of the global earth resistance and the
prospective short circuit current phase
to earth, as well as the current at which
the measurement has been performed
Current used during
the measurement
10.
Measured value of
global earth
resistance higher
than full scale
At the end of the test, if the global earth
resistance value is higher than 1999
Ω
,
the instrument emits a double sound
and displays a screen like this
The symbol HOLD
remains on until a
new measurement
can be taken
CAUTION
To guarantee the correctness of measurements, a certain interval of time is
necessary between a measurement and the following. During this period the
symbol
HOLD
is displayed and no measurement can be taken. When the
symbol
HOLD
disappears, the instrument is ready for a new measurement.
