indicates whether a program is Complete, Running, Halted, or Ready To Start.
If it is not needed during a programming step, it disappears.
The lower right corner displays system alarm conditions, such as low memory
battery, jammed distributor etc. For a list of possible alarms refer to
section 6.4 on page 89. The status bar also lists the valid choices when
entering certain programming information.
The round window of the internal case humidity indicator (Cat. No. 2660)
turns pink when the internal case humidity exceeds 60 percent.
The sampler is equipped with an internal desiccant module (Cat. No. 8849) to
absorb any humidity that may have been trapped in the case during final
assembly. Under normal operating conditions, this desiccant provides long-
term protection against condensed moisture inside the case.
Replacement of the internal desiccant module is only necessary if the
indicator turns pink. (Refer to
replacing the internal desiccant.)
