The following list contains the specifications and calibration factors of the test equipment. The calibration factors were verified using known sources and were calculated according to the following:

Calfac = Refval / Outvol in Engineering Units per Volt

Calfac  Transducer sensitivity

Refval  reference value of the calibration source

Outvol  output voltage of the transducer c) Apparatus to use with Clothes Washer PCB Laser Tachometer Measurement Range up to 30,000 rpm with 1 pulse per revolution Operating Range 90 degree incidence (60 inches apart) 60 degree incidence (15 inches apart) Excitation Voltage 18 to 30 VDC Temperature Range 14 ~ 122 degree F Mounting Thread 5/8-18 UNF 2A Weight 0.85 oz
