Difference measurement and Pass/Fail
13. Difference measurement and Pass/Fail
You can compare the readings of samples with the
value of a previously measured or saved standard.
For saved standards, you can also display whether
the test specimen falls within the limits (Pass) or
outside (Fail).
Up to 50 standards can be saved. They are stored in
a separate area of memory. For each geometry you
can determine:
- A target value
- Maximum and minimum for Pass/Fail,
see Create standard or Change standard.
13.1 Difference
You can use this menu option to turn Difference
measurement on or off. A check mark indicates if
the function is active.
When you turn on Difference, the last standard to be
used is automatically selected.
If no standard is available, choose the function
“Measure standard“ or “Create standard“ to
continue.
13.2 Measure standard
We recommend to perform several readings on the
standard with Statistics turned on.
Memory must be activated to store the measured
standard. Otherwise it will be temporary hold until
another standard is measured.
Activate “Measure standard” and perform the
measurement with operate. With memory on, a
window appears after the last reading where you can
enter the standard’s name.
If you inadvertently select a name that has already
been used, a message will appear in the display
and the arrow will jump back to the first position of
the name.
