When setting up a gage in QC-Gage 4.3, you will need to create a connection. This connection is used to group gages that are on one block so that if the COM port changes for the block, the gages do not need to all be reset. This article reviews the steps for creating a new local gage connection, replacing an existing gage, and assigning a new gage to a Spec Plan.

Create a Local Gage Connection

You can manage your local gage connections in the Tools > Local Gage Connections menu. Here you can add, edit, and delete gages.

  1. Click the Green Plus button image.png to add a new local gage connection. You will be prompted to select a Connection Type.

Assign Gages to a New Workstation

Gages are assigned based on the workstation name. This means if you have to move to a new computer, your gages may appear to be missing when you go to run your spec plan on the new computer. In this case, you can use the Tools > Workstation Gage Assignment menu to rename your workstation and/or assign gages to characteristics in spec plans.

If you don't rename your workstation and you edit your spec plan, you'll find the gages assigned to your characteristics are missing, as in the picture below.

When you run a spec plan with a missing gage, the Missing Gage for Characteristic window will be displayed.
