Long Term Storage
NiCd batteries discharge at the rate of 30% per month at room temperature. Be sure to
fully charge any battery pack retrieved from storage prior to using it in the analyzer.
Recharging
For a complete description of battery pack operations with either the Model 5025A or
Model 5100A Charger/Power Supply (see Chapter 3, "Charger/Power Supply").
CARE OF OPTICS
High concentrations of some compounds, examples of which are listed in Table 10-1,
may cause incorrect readings or degrade the analyzer's cell windows. This could lead to
an error message and require replacement of the windows. The problem may be
minimized by:
Avoiding repeated exposure to such concentrations.
Purging the analyzer thoroughly with clean dry air after exposure to such
concentrations.
