8.3.7 Setting the GO/NG judgment function
The SJ-410 has a GO/NG judgment function. By using this function, a Go/No-go judgment
can be made for the measured surface roughness of a specimen.
One of 6 patterns, Mean, 16%, Max, or Standard Deviation (1 σ, 2 σ, 3 σ) can be selected
as the tolerancing rule of the GO/NG judgment function.
For the SJ-410, the GO/NG judgment function can be set based on the selected
parameters.
■ GO/NG judgment result display
If the GO/NG judgment function is used, the measurement data will be compared with its
upper and lower tolerance limits. If the measurement falls outside the limits, the display
color of the measurement result will change.
If the measurement is within tolerance limits, the “OK” sign will appear to the right of the
parameter name.
If the measurement exceeds the upper limit, the “+NG” sign will appear to the right of the
parameter name, and the displayed measurement result will turn red.
If the measurement falls below the lower limit, the “-NG” sign will appear on the right side of
the parameter name. In addition, the part indicating the measurement result will turn blue.
GO/NG judgment result (within limits, above upper limit, below lower limit)
NOTE
• If the upper or lower limit is set at 0, that limit will not be enabled for GO/NG judgment.
The upper limit and lower limit can be set individually. Therefore, it is possible to
individually disable the GO/NG judgment with the upper/lower limits.
