ground \_\_\_\_

2A. Check cable ground braid to platform ground \_\_\_\_

3\. Turn on GG -- download setpoints \_\_\_\_

4\. Pulse GG with pulser -- check monitor out for all sectors \_\_\_\_

5\. Calibrate outputs if needed. \_\_\_\_

6\. Check that ground sleeves in back of rack are in place. \_\_\_\_

7\. When done, ensure trigger cable from TCD is plugged in \_\_\_\_
