measurement
The message "Measuring" on the display means that the instrument is
measuring. During this phase never disconnect test leads.
8. At the end of the test, if the earth
resistance value is lower than 1999Ω,
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
9. If a test current of 100mA has been
selected and the earth resistance value
is lower than 1999Ω, 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
10. At the end of the test, if the global earth
resistance value is higher than 1999Ω,
the instrument emits a double sound
and displays a screen like this
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.
