  • What occurs when probe does not have enough side clearance around the tip?
    b. crosstalk occurs
    c. side view occurs
    a. linear range occurs
    d. voltage drops
  • What is the primary function of a transducer’s performance curve?
    c. to reveal the transducer’s scale factor and linear range
    c. to be used as a maintenance record
    a. to calibrate the proximitor
    b. to set the gap on the probe
  • When do side view problems occur?
