Tech Article #8 - Smart Level PRO 360 Recalibrating

Like all measurement instruments the PRO 360 must periodically be monitored for accuracy.  The PRO 360 should be tested daily with the simple procedure outlined below.  If it is found to be out of calibration, it is easily recalibrated on site using Superset and an eight-step procedure that realigns the unit through it entire 360°.

ACCURACY TEST

Perform this simple test each day before using the PRO 360.  Also perform it anytime the PRO 360 has been dropped or is being used in an environment that varies more than 5° from the environment in which it was last calibrated.

• Position the PRO 360 with the display facing you on a clean, flat horizontal surface.  It doesn’t have to be exactly level.  Wait 10 so the unit is completely settled and note the angle on the display.
•   Rotate the unit end-for-end so the display is facing away from you.  Be sure to set the PRO 360 in exactly the same spot, and wait 10 seconds and note the angle on the display.
• Now roll the unit toward you so that the display is facing you, but the lettering on the face of the unit is upside down.  Wait 10 seconds and note the angle on the display.
• Finally, rotate the unit end-for-end so the display is facing away from you (the lettering should still be upside down).  Wait 10 seconds and note the angle on the display.
• If any of the 4 measurements varies from any other by more than 0.1° you must recalibrate your unit before using it further.

SUPERSET

Superset recalibrates the PRO 360 through its entire 360° range by electronically recording four horizontal and four vertical settings.  It should be performed whenever the accuracy test shows a discrepancy of 0.1° or more.

HOW TO PERFORM SUPERSET

Turn on the PRO 360 and place it on a flat surface.  You can use any horizontal surface within 10° of level and any vertical surface within 10° of plumb to perform Superset.  You must use the same surfaces throughout the entire process!

NOTE: Each time you reposition the PRO 360 during Superset, wait a minimum of 10 seconds before pressing the HOLD button to advance to the next step.

STARTING SUPERSET

• Press and hold the HOLD button and ALT ZERO button simultaneously.  Keep them depressed for approximately 3 seconds.
• Release the buttons when the symbol “SUP” appears.  A “0” within flashing brackets will then appear.  These brackets are composed of four horizontal and four vertical segments.

SUPERSET HORIZONTAL SETTINGS

[1]

• Unit faces you and white lettering is right side up.
• Align with an edge or line-wait 10 seconds.
• Press HOLD button until [1] appears.

[2]

• Rotate the unit so it faces away from you, the lettering should still be right-side up.
• Align with the same edge or line-wait 10 seconds.
• Press HOLD button until [2] appears

[3]

• Roll unit so it faces you, the lettering should be upside down now.
• Align with same edge or line-wait 10 seconds.
• Press HOLD button until [3] appears.

[4]

• Rotate unit so it faces away from you, the lettering should still be upside down.
• Align with same edge or line-wait 10 seconds.
• Press HOLD button until [4] appears.

YOU HAVE NOW COMPLETED HALF OF SUPERSET

SUPERSET VERTICAL SETTINGS

[5]

• Place unit against vertical surface so it faces you, the lettering on the face should read from top to bottom.
• Align with an edge or line-wait 10 seconds.
• Press HOLD button until [5] appears.

[6]

• Roll the unit so it faces away from you, the lettering should still read from top to bottom.
• Align with same edge or line-wait 10 seconds.
• Press HOLD button until [6] appears

[7]

• Rotate the unit end-for-end so it faces you, the lettering should now read bottom to top.
• Align with edge or line-wait 10 seconds.
• Press HOLD button until [7] appears.
