  1.004  DISP         Disconnect the test leads and the battery eliminator
  1.004  DISP         if attached. Open the battery compartment, and
  1.004  DISP         disconnect the battery. Remove the three phillips-head
  1.004  DISP         screws from the bottom of the case. Turn the instrument
  1.004  DISP         face-up, and grasp the top cover at both sides of the
  1.004  DISP         input connectors. Then, pull the top cover from the UUT.
  1.005  DISP         Re-connect the battery.
  1.005  DISP         Ambient temperature: 21C - 25C.
  1.005  DISP         Relative humidity: less than 80%.
  1.005  DISP         Allow the UUT 30 min. to stabilize.
  1.006  DISP         Turn the UUT ON.
