Hach 900 MAX manual Internal Humidity Indicator, Section, Status Bar

Section 1

Status Bar

The Status Bar appears along the bottom edge of the display. The appearance of the status bar changes depending upon the function performed (Figure 1). The lower left corner of the Status Bar 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.

1.2.3 Internal Humidity Indicator

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 section 7.10 on page 103 for details on replacing the internal desiccant.)
