### MP-055 SP600 interface card A/D conversion failure

While the SP600 analog probe was in use the Renishaw AC2 interface card was commanded to perform an A/D conversion but that conversion was not complete within 200 microseconds. This error indicates a critical failure of the interface card.

What you should do

1. To clear the error, power the MP down.

2. Power the MP back up.

3. If the error reoccurs, call your Giddings & Lewis service representative.
