SHOCK HAZARD. FAN HAZARD. Only qualified, service-trained personnel who are
aware of the hazards involved should remove instrument covers. Disconnect the
power cable and any external circuits before removing instrument covers.
Two switches control the access to calibration commands. The switches are located on the interface
board and are accessible by removing the blower and interface covers (see figure).
Accessing the Calibration Switch
Step 1. Remove the blower cover. Remove three screws from the top of the cover and two screws on
the sides. Tilt the cover up and slide it out.
Step 2. Remove the interface cover. Remove the three screws along the left side of the unit. Then
remove the screw at the front of the cover. Lift off the cover.
Step 3. The calibration switch is on the interface board near the ribbon cable. To change the
calibration switch settings, use a small screwdriver to move the switches.
Do not use a pencil to move the switches. Any graphite dust that gets on the
switches will conduct electricity.
Step 4. Replace all covers when finished.
