Maintenance 

5.1  Routine Maintenance 

Aside from normal cleaning and checking for leaks at the gas 

connections, routine maintenance is limited to replacing fuses, and 
recalibration. For recalibration, see Section 4.4 The Zero and Span 
Functions. 

WARNING: 

SEE WARNINGS ON THE TITLE PAGE O F THIS 

MANUAL. 

 

5.2  Fuse Replacement 

The fuse compartment is located  adjacent to the universal power 

supply on the rear panel of the Control Unit. To remove or replace a fuse : 

1.  Place small screwdriver in notch, and pry cover off, as shown 

in Figure 5-1.
