  1.002  HEAD         EQUIPMENT SETUP
  1.003  DISP         This procedure requires a 50-turn Toroid Coil.
  1.003  DISP         Refer to the 31/33 Instruction Manual figure 7, page 32
  1.003  DISP         for directions for constructioning a suitable coil.
  1.004  HEAD         CALIBRATION ADJUSTMENT
  1.005  DISP         Disassemble the meter by removing the four screws on the
  1.005  DISP         case back.
  1.006  DISP         Remove the battery cover and front panel.
  1.007  DISP         Turn on the meter and use a DMM to verify that the
  1.007  DISP         battery level is between 7 and 9 volts.  If the battery
  1.007  DISP         does not meet this criteria, replace the battery before
  1.007  DISP         proceeding with the procedure.
  1.008  DISP         The Test equipment should be allowed to warmup and
  1.008  DISP         stablize for at least 30 minutes before starting the
  1.008  DISP         adjustments.
