NOTES:
[1] Conversion Factor 1 in/sec = 0.0254 m/sec.
[2] 1Hz = 60 cpm (cycles per minute).
[3] Current will fluctuate at frequencies below 5 Hz.
[4] Typical value.
[5] 1/8" hex Allen key required for English version, 3mm hex Allen key required for metric
version.
[6] Stud torque must exceed sensor hex nut torque to ensure proper dismantling.
