Refer to the Agilent 5530 Getting Started Guide and online help for more 
information about using this screen. Otherwise, you are finished making 
the measurement.
Storing the hardware
Return the angular position measurement kit components to the kit case 
when you have finished using them.
NOTE Before you store the precision index table:
1. Install the locking ring and bolt to hold the top and bottom together.
    Tighten the bolt securely.
2. After performing step 1, disengage the locking loops. This helps extend
    their useful life.
Maintenance
Precision index table
The precision index table’s top and base have 360 matching teeth 
comprising a Hirth coupling. For best performance of the table, these 
teeth should be as clean as possible. You should visually inspect the teeth 
each time you use the table. The procedure below is recommended for 
cleaning Hirth coupling teeth.
WARNING BE SURE TO WEAR APPROPRIATE PROTECTIVE SHIELDING 
AND CLOTHING WHEN WORKING WITH COMPRESSED AIR 
AND ACETONE.
1 With the precision index table’s top and bottom separated, use compressed 
air to blow loose material from the Hirth coupling teeth.
2 If necessary, use an acid brush to remove material from the teeth.
3 If necessary, use acetone and the acid brush to remove material from the 
teeth.
