5.1.2.4 ANOMALOUS CASES:
Anomalous cases which can occur during the following "AUTO", "R+", "R-", "R+TIMER",
"R-TIMER"
CAL LOW
Ω
o 5.75
Ω
216
mA
5
s
AUTO
In case a value of Ravg or R+ or R-
higher than or equal to 5
Ω but
lower than 99.9 Ω (9.99Ω in
R+TIMER and R-TIMER) was
detected, at the end of the test the
instrument emits a long sound
signal displays one screen similar to
the screen alongside.
ATTENTION:
average value
of Ravg higher
than 5
Ω.
The tests can be stored pressing the SAVE key twice (according to
paragraph 0).
CAL LOW
Ω
o> 99.9 Ω
- - - mA
AUTO
In case one of the following modes
AUTO, R+, R- and a Ravg or R+ or
R- higher than 99.9
Ω was selected,
at the end of the test the instrument
emits a long sound signal and
displays the screen alongside.
The tests can be stored pressing the SAVE key twice (according to
paragraph 0).
99.9 Ω is the
maximum
value which
can be
measured in
the LOW
Ω
AUTO or
R+ or R-
mode.
SAVE
Selected mode (in the picture the mode AUTO
is indicated as example).
ATTENTION: value of R
avg
or R+ or R- is too
high.
Only in case
the mode
R+TIMER or
R-TIMER was
selected.
Selected mode (in the picture the
mode AUTO is indicated as
example).
SAVE
CAL LOW
Ω
o A
VOL AG
If the terminal voltage is higher than
10V, the instrument does not carry
out the test and displays the screen
alongside for 5 seconds after which,
the instrument displays the screen
relative to the precedent selected test
mode LOW
Ω under AUTO mode.
ATTENTION:
the test was
not made
Due to voltage
at the terminal
ends.
THIS RESULT CANNOT BE SAVED
