  1.003  HEAD         EQUIPMENT SETUP
  1.004  DISP         This procedure requires a 50-turn Toroid Coil.
  1.004  DISP         Refer to the 31/33 Instruction Manual figure 7, page 32
  1.004  DISP         for directions for constructioning a suitable coil.
  1.005  HEAD         CALIBRATION ADJUSTMENT
  1.006  DISP         Use a Phillips-head screwdriver to remove the back from
  1.006  DISP         the 30-Series meter to be calibrated. Wrap a rubberband
  1.006  DISP         around the case and battery to keep the battery in
  1.006  DISP         place. Note the location of the calibration point.
  1.007  DISP         Connect the 5500A/COIL to the 5520A 20A & AUX Lo
  1.007  DISP         terminals.
  1.007  DISP
  1.007  DISP         Clamp the meter around the toroid center conductor
  1.007  DISP         bundle, positioning at the alignment marks.
  1.008  DISP         Insert a small insulated screwdriver into the
  1.008  DISP         calibration potentiometer and turn the UUT on.
