"P-PE" Test Results
 The instrument, at the
end of the test, does a
double sound signal ,
that mean by the test is
OK and it shows a
screen like this on side.

Voltage Measured
The Prospective Short Circuit Current is calculated according to one of the relationship
indicates in paragraph 6.3.2 for Phase-Protection conductor connection.
 You can save these results by pressing the SAVE button twice or by pressing
the SAVE button and then the ENTER button.
6.3.5. Anomalous results for "P-P", "P-N", "P-PE" Test
 The message " NO
IMP57 " indicate that
IMP57 doesn't reply to
RS232 commands of
the MASTER
instrument. Please
check if the MASTER
instrument is connected
to IMP57 through
C2001 optical cable
and the STATUS LED
is green.
