Command Reference

CALL 1

The CALL 1 command determines the bridge settings and 
ensures that the subsequent command (CROP or CRSH) 
performs an open or short compensation for all 69 test fre-

quencies. It is necessary to first send CROP or CRSH be

-

fore the compensation is performed.

CROP

The CROP command performs an open compensation. 
The HM8118 automatically reports immediately if a com-
pensation was successful (0) or if it failed (-1).

CRSH

The CRSH command performs a short compensation. The 
HM8118 automatically reports immediately if a compensa-
tion was successful (0) or if it failed (-1).

XALL?

The XALL? query queries the measurement values of the 
main measurement value display, the secondary measure-
ment value display and the number of sorting bins. The 
measurement values are issued separated by a comma. If 
the binning interface is not activated / not integrated or if 
the current measurement is invalid, the sorting bin value 
99 issued.

XMAJ?

The  XMAJ? query queries the measurement value of the 
main measurement value display. If the measurement va-
lue display is set to percentage deviation and if the nomi-
nal measurement value is „0“, an error message will be 
issued.

XMIN? 

The XMIN? query queries the measurement value of the 
secondary measurement value display. If the measurement 
value display is set to percentage deviation and if the no-
minal measurement value is „0“, an error message will be 
issued.

XDLT?

The XDLT? query queries the absolute deviation between 
the measurement value and the nominal measurement va-
lue (see also PREL command). If the automatic measure-
ment mode (AUTO) is selected, an error message is 
issued.

XDMT?

The  XDMT? query queries the relative deviation between 
the measurement value and the nominal measurement va-
lue (see also PREL command). If the nominal measurement 
value is set to „0“ or if the automatic measurement mode 
(AUTO) is selected, an error message is issued.

10.3  Command List Binning Interface

(only with integrated binning interface HO118)

XBIN?

The XBIN? query queries the number of sorting bins for the 

current measurement. If the binning interface is not swit-
ched on / not activated or if the current measurement is in-
valid, the sorting bin value 99 issued.

BBUZ(?) i

The BBUZ command activates (i=1) or deactivates (i=0) the 
alarm function of the binning interface. The BBUZ? query 
queries the current status of the alarm function.

BCLR

The BCLR command deletes the nominal values and limits 
for all sorting bins. It also deactivates the binning interface.

BING(?) {i}

The BING command locks (i=0) and enables (i=1) the bin-
ning. If no sorting bin is opened or if the measurement 
mode „AUTO“ is selected for the HM8118 , an error mes-
sage is issued.

BLIH j,(?) {x}

 

The BLIH command sets the maximum limit (i = 0) of a 

sorting bin j to x % between 0 and 7. The  BLIH? query 

queries the maximum limit (i = 0) of the sorting bin.

BLIL j,(?) {x}

The BLIL command sets the lower limit (i = 1) for a sorting 

bin j x % between 0 and 7. The lower limit must be less 

than or equal to the upper limit. If no lower limit has been 
set, the HM8118 applies the negative value of the upper li-
mit as lower limit. The query BLIL? queries the lower limit (i 
= 1) of the sorting bin.

BNOM i,(?) {x}

  

The BNOM command set sets the nominal value of the 
sorting bin i to the value x. The value i can be anywhere 
between 0 and 8 (sorting bin 8 is the QDR sorting bin for 
failures). If no nominal value has been set for the sorting 
bin, the HM8118 applies the nominal value of the subse-
quent lowest numbered sorting bin with a nominal va-
lue of unequal 0 (multiple sorting bins can have the identi-
cal nominal value without having a value entered for each 
sorting bin). The lowest numbered active sorting bin must 
have a selected nominal value. The sorting bin 0 must al-
ways be set for the binning to work. The query BNOM? 
queries the nominal value of the sorting bin.
