C o m m a n d r e f e r e n c e
RNGH? requests the status of the manual range
selection.
VOLT(?) {x}
The VOLT command sets the measuring voltage
to x volts, x may vary between 0.05 to 1.5 V. Any
intermediate values tried will be rounded to the
next higher (0.01 V steps) available value.
VOLT? requests the status of the measuring vol-
tage.
9.2 Control Commands
PREL(?) {x}
The PREL command defines with x the relative
deviation of the main measurement result. This
command will generate an error message if au-
toranging was selected.
The unit of x is:
– Ohm:
with R+Q, Z+
Θ
and R+X measurements,
– Henry:
with L+Q, L+R and M measurements,
– Farad:
with C+D and C+R measurements and
– Siemens:
with Y+
Θ
and G+B measurements.
PREL? requests the present status of the para-
meters.
SREL(?) {x}
The SREL command sets with x the relative de-
viation of the second measurement value. This
command will generate an error message if auto-
ranging or M measurement (because of inductive
influences) were selected.
The unit of x is:
– Ohm:
with L+R, C+R and R+X measurements,
– Degrees:
with Z+
Θ
, Y+
Θ
and N+
Θ
measure-
ments.
– No unit is used:
for all other measurements.
SREL? requests the present status of the parame-
ters.
STRT
The STRT command starts a measurement. During
the course of a measurement this command will
be ignored.
*TRG
The *TRG command is the general command con-
forming to IEEE to start a measurement, hence its
function is identical to STRT.
CALL 0
By sending the CALL 0 command the instrument
will be set to single calibration. Only the current
set frequency will be calibrated by using the CROP
or CRSH command after the CALL 0 command.
CALL 1
By sending the CALL 1 command the instrument
will be set to calibrate all 69 test frequencies at
once. The 69 test frequencies will be calibrated by
using the CROP or CRSH command after the CALL
1 command.
CROP
The CROP command performs an open calibration.
Afterwards the HM8118 reports success (0) or
failure (-1).
CRSH
The CRSH command performs a short calibration.
Afterwards the HM8118 reports success (0) or
failure (-1).
OUTP(?) {i}
The OUTP command sets the display of the main
measurement value to:
– normal:
(i = 0),
– relative deviation in percent:
(i = 1) or
– absolute deviation:
(i = 2).
OUTP? requests the present status of the para-
meters.
OUTS(?) {i}
The OUTS command sets the display of the second
measurement value to:
– Normal:
(i = 0),
– absolute deviation:
(i = 1) or
– relative deviation in percent:
(i = 2).
OUTS? requests the present status of the para-
meters.
9.3 Commands for the request of results
XALL?
The XALL? requests the status of the main mea-
surement value, secondary measurement value
and the number of bins. The 3 answers are sepa-
rated by commas.
XBIN?
The XBIN? requests the number of bins used for the
actual measurement. If no binning was selected or
if the actual measurement was faulty the number
99 will be sent.
XMAJ?
The XMAJ? requests the main measurement result.
If the measurement display is set to percentage
deviation and if the nominal value is zero, an error
message will be sent.
XMIN?
The XMIN? requests the secondary measurement
result. If the measurement display is set to per-
centage deviation and if the nominal value is zero
an error message will be sent.
XDLT?
The XDLT? requests the absolute deviation bet-
ween the measurement result and the nominal
value (see also the PREL command). If AUTO mode
is selected, an error message will be sent.
XDMT?
The XDMT? requests the relative deviation between
the measurement result and the nominal value
(see also the PREL command). If the AUTO mode
is selected or if the nominal value is zero, an error
message will be sent.
9.4 Binning Commands
(only with implemented Binning Interface HO118)
BBUZ
The BBUZ command activates (deactivates) the
alarm function of the Binning Interface,
BCLR
The BCLR command erases the nominal values
and the limit values of all bins. This command also
turns the binning function off.
BING(?) {i}
The BING command disables (i = 0) or enables (i
= 1) the binning. If no bins are available or if the
AUTO mode is selected, an error message will be
sent.
BLIH j,(?) {x}
The BLIH command sets the upper limit (i = 0)
of the HM8118 BIN j to x % in the range of 0 to 7.
The BLIH? requests the upper limit (i = 0) of BIN j.
BLIL j,(?) {x}
The BLIL command sets the lower limit (i = 1) of
the HM8118 BIN j to x % in the range of 0 to 7. The
