MZ-805 L/C/R meter
As with simple pass/fail sorting, bin 8 is the failure bin for the appropriate
minor parameter and bin 9 is the general fail bin.
Multiple bin sort schemes can be quite complicated; it is therefore a good
idea to write down the binning set—up before programming is started and to
save the set—up once programming is complete.
Overlap Sorting
Overlap sorting is used when components are to be sorted into bins
according to their deviation from a nominal value, for example sorting a
particular resistor value into ± 0.1%, ± 0.5% and ± 1% selections.
To set up this type of binning first select the measurement type to be
made, e.g. R + Q, set the measurement frequency and select series or parallel
mode as required.
Select bin 0 and set the nominal value and tightest tolerance to be
selected (i.e. 0.1% in the case of the example) using the Nominal and Limit
keys exactly as described for simple pass/fail testing. Note that, since the limits
are symmetrical, it is only necessary to set +LIM to 0.1%; if –LIM is 'closed'
(dashes shown in the display) the lower limit is automatically —0.1%.
Next select bin 1 in a similar way to bin 0 and set its limits to the next
tightest tolerance (i.e. 0.5% for the example). In the same way as for bin 0 it is
only necessary to set +LIM to 0.5%; –LIM will default to —0.5% if no limit is set.
Also note that it is not necessary to set a nominal for bin 1 (and any successive
bins that use the same nominal); if the nominal is left 'closed' (dashes shown in
the display) the nominal of the next lower bin, in this case bin 0, is automatically
used. Note that if bin 0 does not have a nominal value and limits, selecting Sort
will cause the display to show the message Err bin0.
Set the +LIM limit of bin 2 to 1% to complete the example given.
Set the minor term limit (Q in the case of R + Q measurements) in bin 8 if
required; bin 8 is ignored if the limit is 'closed' (dashes shown in the display).
Parts that fall into more than one bin are assigned to the lower numbered
bin, Thus the tightest tolerances should be assigned to the lowest bin number,
as in the example.
Unused bins should be 'closed' (indicated by dashes) by using the clear
bin function.
Parts that do not fall into the pass bins or bin 8 are assigned to bin 9, the
general fail bin.
