Introduction
Function keys
There are three function keys that are used while operating the sampler (refer to
). These functions are dedicated keys to allow quick access. They are the white keys
located just above the numeric keypad.
3.6.2 Liquid crystal display
3.6.3 Internal humidity indicator
The internal case humidity indicator (2660) turns pink when the internal case humidity
exceeds 60%.
The sampler is equipped with an internal desiccant module (8849) to absorb any humidity
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
for details.
