  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         Disassemble the meter by removing the four screws on the
  1.006  DISP         case back.
  1.007  DISP         Remove the battery cover and front panel.
  1.008  DISP         Turn on the meter and use a DMM to verify that the
  1.008  DISP         battery level is between 7 and 9 volts.  If the battery
  1.008  DISP         does not meet this criteria, replace the battery before
  1.008  DISP         proceeding with the procedure.
  1.009  DISP         The Test equipment should be allowed to warmup and
  1.009  DISP         stablize for at least 30 minutes before starting the
  1.009  DISP         adjustments.
  1.010  DISP         Connect the 5520A NORMAL Hi & Lo to the UUT V Ohm & COM
  1.010  DISP         terminals.
  1.010  DISP
  1.010  DISP         Connect the 5500A/COIL to the 5520A 20A & AUX Lo
  1.010  DISP         terminals.
  1.010  DISP
  1.010  DISP         Clamp the meter around the toroid center conductor
  1.010  DISP         bundle, positioning at the alignment marks.
