1. What is the recommended minimum time that the Axiom must be powered on BEFORE performing a field calibration?
30 seconds
1 minute
There's no recommendation
2 minutes
2. Referencing the image below, why is the "Measure Job" button greyed out?

The use of numbers
4. When starting a run and taking the first measurement point, where should the foot pad (on the kickstand side) be in relation to you?
*
It's the closest foot to me.
It's the farthest foot from me.
Orientation does not matter.
5. Referencing the image below, in the Measuring screen. Why is the Floor Levelness value displaying 0.00?
*
No FL data has been taken.
The app displays the FL values until the end of the Run.
Not enough measurement points has been taken.
6. If you mistakenly taken a measurement point and want to delete it. Does the Axiom app allow it?
*
No. This is something you need to do in the Report Generator.

Yes. Press on the Trash can icon on the Measuring Screen.
No. Go into the file manager on the phone and delete from there
7. True or False: The Axiom FF/FL app mode will allow you to save runs that are less than 11 feet long.
*
True
False
8. True or False: It it required for you to enter a run length number for each of the Runs

*
Press and Hold on the corresponding job file name

*
It overwrites all of the contact info with new contact info.
It imports a specific project file which contains measurement data taken with the Axiom 1155.
23. Referencing the image below, In this example of the Table of Results in the Report Generator the overall FF/FL numbers for Surface 1 have yet to calculate. Why?
*
Not enough measurement data was collected in order to calculate the overall FF/FL.
Because the Area of each section still needs to be entered, and once it is, the overalls will automatically calculate.
24. Prior to taking each Run, it's good practice to do what?
*
Inspect the foot pads to make sure there is no debris sticking to either of them.
Sweep the floor clean of debris along the line that you are taking the run measurements on.
