Maintenance Check Out Procedure
It is recommended that this maintenance check be performed once per week and
the Maintenance Record Sheet (Table 31) be completed at the same time. It is
recommended that the completed record sheets are saved in a secure location.
The information on the sheets can provide a time based record of system
operation and may be useful for troubleshooting.
The following procedure should be performed on a periodic basis and the
Maintenance
Record Sheet
should be completed (Table 31):
1. Observe the present status of the analyzer indicated on the
Analysis 1
and
Analysis

panels. Record any fault conditions or abnormal values. Record the displayed values
for the cell / probe temperatures as well as the cell pressure.
