Selects the data log and/or the event log. DATA LOG—shows the measurement
values. Select start time, number of hours and/or number of readings. EVENT LOG
—shows all analyzer information (e.g. alarms, warnings, configuration changes,
and so on.). Select start time, number of hours and/or number of readings.
Table 2 Analyzer data
Definition
Temperature of the colorimeter cell block heater (ideally 49.8 °C to 50.2 °C (121.64 °F
to 122.36 °F))
Reagent temperature before it enters the colorimeter
Air temperature inside the electronics area
Sample pre-heater block temperature (typically 45 °C to 55 °C (113 °F to 131 °F) but
could reach 58 °C (136.4 °F))
Reagent air pressure in the reagent bottles (ideally 3.95 to 4.10 psi)
Depends on condition of colorimeter cell and age of analyzer (typically 7,200 to
40,000 counts)
Approximate sample flow into the colorimeter, measured during the flush cycle
Sample pressure before the pre-heater block (ideally 2 to 4.5 psi depending on
incoming sample pressure)
Sample pressure after the sample pre-heater, which is used to calculate the sample
flow. The sample pressure is almost zero when the flush is set to off and is
approximately 0.2 psi when the flush is on (depends on inlet pressure and flow).
