EZ-Cal Scan Tools

The EZ-Cal Scan Tools interface with the machine’s control system to provide system information 
and to allow adjustment. The EZ-Cal receives its power from the GP500 or GP440. The system must 
be powered up by pulling out both Emergency Stop Switches. You must also select Base or Platform 
depending on the station from which you will operate.

Onboard EZ-Cal Option -- Lower Controls Box

To use and operate the onboard EZ-Cal, set the 
Base/Platform Key switch to Base, then open the 
door to the Lower Controls Box. The onboard EZ-
Cal scan tool provides the same functionality as the 
hand-held unit.
