STATIC HEIGHT SENSOR MEASUREMENTS

RSC:
Date:
Distance from Ground to Sensor Glass (mm):	Left:	Center	Right

 

Left Sensor
Position	Values Shown on Monitor for Dif Ht(Note 1)					Avg. of Heights (mm)	Actual Block Height (Note 2) (mm)	Actual Minus Average (mm)	Std Dev. of Heights (mm) (Note 3)
	Test 1	Test 2	Test 3	Test 4	Test 5
Base Plate + 25 mm Block + Calibration Plate
Base Plate + 50 mm Block + Calibration Plate
Base Plate + 75 mm Block + Calibration Plate
Base Plate + 100 mm Block + Calibration Plate

 

Center Sensor
Position	Values Shown on Monitor for Dif Ht (Note 1)					Avg. of Heights (mm)	Actual Block Height (Note 2) (mm)	Actual Minus Average (mm)	Standard Dev. of Heights (mm) (Note 3)
	Test 1	Test 2	Test 3	Test 4	Test 5
Base Plate + 25 mm Block + Calibration Plate
Base Plate + 50 mm Block + Calibration Plate
Base Plate + 75 mm Block + Calibration Plate
Base Plate + 100 mm Block + Calibration Plate

 

Right Sensor
Position	Values Shown on Monitor for Dif Ht (Note 1)					Avg. of Heights (mm)	Actual Block Height (Note 2) (mm)	Actual Minus Average (mm)		Standard Dev. of Heights (mm) (Note 3)
	Test 1	Test 2	Test 3	Test 4	Test 5
Base Plate + 25 mm Block + Calibration Plate
Base Plate + 50 mm Block + Calibration Plate
Base Plate + 75 mm Block + Calibration Plate
Base Plate + 100 mm Block + Calibration Plate

Note 1: Do Test 1 for each block position. Then repeat procedure for other tests. Let computer take 500 readings before recording value.

Note 2: Record actual height of block stamped on block in this column

Note 3: Calculate standard deviation using the STDEV function in Excel
