SPECIAL FUNCTION 2: GO/NOGO
PROGRAMMING PARAMETER Pr24 set to 2
In certain applications (particularly with a ProTable or ProPanel) it may be
desirable to program upper and lower measurement tolerances to gauge parts.
If the measurement falls within the programmed tolerance, a “Go” condition
occurs. If the measurement is not within the upper or lower tolerance, a “No
Go” condition occurs.
The General Purpose DRO can store up to 16 individual measurement indexes
(SET BY PR25), each with its own upper and lower tolerance. Each measurement
index is identified with a number from 1 to 16.
A Go/No Go Editor is used to enter the individual upper and lower tolerances
for each measurement index.
To enter the Go/No Go Editor press F3.
This will select one of the 16 measurement indexes to be programmed. Each
press of F3 will display Go X
Go XGo X
Go X where x is a number from 1 to 16 representing the
particular index to be edited. After the last number is reached (determined by
the setting of Pr25), pressing the F3 key again will display Go oFF
Go oFFGo oFF
Go oFF indicating
that the Go/No Go function is turned off. (The F4 key works similarly but
decrements through the list).
Once a measurement index is selected the LCD will alternate between the
current Encoder position and Go

Go or no Go
no Gono Go
no Go depending on the current position
and programmed tolerances for that index.
Next, press and hold the UNITS key and momentarily press the F4 key.
The LCD will display GoX U

X is the measurement index
and U

U indicates the upper tolerance is to be programmed. The LCD will then
display the current programmed upper limit.
Use the + and – keys to set a new upper limit.
Next, momentarily press F3.
The LCD will display GoX L

Next, exit the Go/No Go Editor by momentarily pressing F3.
