Judging the Tolerance
By setting the upper and lower tolerance limits in advance, the acceptability judgment can be
automatically performed. The acceptability judgment will be displayed on the LED and the LCD screen,
meaning it can be easily determined whether the value falls within the tolerance range.
Operation panel
Red: Upper tolerance limit exceeded.
Orange: Lower tolerance limit exceeded.
Green: Within the tolerance range.
LCD screen
[+NG]: Upper tolerance limit exceeded.
[-NG]: Lower tolerance limit exceeded.
[GO]: Within the tolerance range.
To perform the acceptability judgment automatically, register the upper and lower tolerance limits, and
then enable the acceptability judgment function.
Tips
You can change the length of time that the LED is lit. For details about changing the settings, "3.8
