reference, void and software version
(Firmware).
F? <CR> Requests current measurement
function. The instrument returns one
of the following strings:
VOLT<CR>
AMP<CR>
MAMP<CR>
OHM<CR>
DIODE<CR>
TDGC<CR>
TDGF<CR>
DB<CR>
M? <CR> Requests current measurement
mode. The instrument returns one
the eight following strings:
AC BEEP-ON <CR>
AC BEEP-OFF <CR>
DC BEEP-ON <CR>
DC BEEP-OFF<CR>
AC+DC BEEP-ON <CR>
AC+DC BEEP OFF <CR>
BEEP ON <CR>
BEEP OFF <CR>
The fi rst six answers are obtained
in voltage and current functions, the
last ones in the others.
D? <CR> Request for current display option.
The instrument sends back one of the
strings:
HOLD<CR>
REF<CR>
HOLD+REF<CR>
NORMAL<CR>
The REF string corresponds to the
front panel OFFSET mode. The NOR-
MAL string indicates that the display
is neither on HOLD nor on REF.
R? <CR> Requests for current measurement
range. The instrument returns one of
the following strings:
NUM<CR>
NUM AUTO<CR>
The fi rst NUM fi eld represents a di-
gital character indicating the current
range number. Where applicable, a
second fi eld is displayed indicating
that the automatic range change
mode is active. Note that the range
numbers correspond respectively to:
R e m o t e c o n t r o l
(1 - > 0.5 V, 0.5k , 500 μA, T°C, T°F)
(2 - > 5 V, 5 k , 5 mA, Diode)
(3 - > 50 V, 50 k , 50 mA)
(4 - > 500 V, 500 k , 500 mA)
(5 - > 1000 V, 5 M )
(6 - > 50 M , 10 A)
P? <CR> This command alone is used for reco-
vering complete parameter settings
of the equipment.
The instrument returns:
string_F, string_M, string_R,
string_D <CR>
string_F is one of the responses
returned by command F?
string_M is one of the responses
returned by command M?
string_R is one of the responses
returned by command R?
string_D is one of the responses
returned by command D?
S? <CR> Request to send current measure-
ment. The instrument returns a string
in the shape:
NUM UNIT <CR>
NUM represents the digital value
fi eld in IEEE NR2 format (in our case,
fi ve signifi cant digits at most with
the presence of a decimal point). The
signifi cant digits are those of the front
panel display.
UNIT is the fi eld giving, as suggested
by the name, the unit or a submul-
tiple thereof. The possible values are
identical to that of the front panel.
E? <CR> Request for status of command error
indicator. The instrument returns:
O<CR> if the command or commands
received previously have not gene-
rated an error,1<CR> if one of the
com-mands received previously has
generated an error.
The use of this command resets the
error indicator to 0. Indeed, in the
event of an error, as long as the user
has not requested the status of the
indicator through this command, the
latter will remain set even if other
commands go through without er-
rors.
