> Make 4 1/2 Minute Recordings

We suggest that you generally make 4 1/2 minute recordings with the ShockClock.  This is enough to get a good sampling so the “Average” numbers are meaningful.

 

> Set Up Preferences

Be sure to setup Vehicle Preferences before collecting data. See 5.2 Preferences

 

> Test Day Preparation

Mount the ShockClock to the bike in your shop or garage before going to the track if possible.

 

Test the system to make sure everything is working.  Do a trial download of a hand recording to make sure everything is working properly.

 

> Extras You May Need

Here is a list of recommended items for a day of testing:

• Digital Thermometer – est. price $12
• AA Battery tester and extra AA batteries
• Zip Ties – bring lots of them!
• Assorted bolts & washers – 6 & 8 mm
• Steel Flat Stock – ¾ x 1/8 x 3 or 4 feet for making any custom mounting brackets (don't use aluminum – it can break)
• Tools: Drill Motor & Drill Bits, Hacksaw

 

> Extra Transducer Wave-Guide Tubes

  See 1.4 Accessories.
