instrument generated
the Nominal test
Voltage, the instrument
emits a double sound
signal indicating the
positive outcome of
the test and displays
one screen similar to the
screen alongside.
In order to evaluate the test you must compare the result with the limits indicated in the
Guidelines (see Table1).
The displayed result can be stored pressing the SAVE key twice (according to
paragraph 9.1).
