DC BEEP-OFF<CR>
AC+DC BEEP-ON <CR>
AC+DC BEEP OFF <CR>
BEEP ON <CR>
BEEP OFF <CR>
The first 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
NORMAL 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 first NUM field represents a digital
character indicating the current range
number. Where applicable, a second
field is displayed indicating that the
automatic range change mode is ac-
tive. Note that the range numbers cor-
respond respectively to:
(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
recovering complete parameter set-
tings 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?
R e m o t e
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 field
in IEEE NR2 format (in our case, five
significant digits at most with the
presence of a decimal point). The
significant digits are those of the front
panel display.
UNIT is the field giving, as suggested
by the name, the unit or a submultiple
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 generated
an error,1<CR> if one of the com-
mands received previously has gene-
rated 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 errors.
