Remarks
The measured value for
dU/dt was less than
0.1 %/s
The message is also
displayed if
TEST U-Match is still set
to ON and another test
function is to be carried
out
The measured value for
df/dt was less than
0.05 %/s. The message
is also displayed if
TEST f-Match is still set
to ON and another test
function is to be carried
out
