Table 2 Analyzer data
Element Definition
CELL TEMP Temperature of the colorimeter cell block heater (ideally
49.8 °C to 50.2 °C (121.64 °F to 122.36 °F))
REAGENT TEMP Reagent temperature before it enters the colorimeter
AMBIENT TEMP Air temperature inside the electronics area
Table 2 Analyzer data (continued)
Element Definition
SAMPLE TEMP Sample pre-heater block temperature (typically 45 °C to
55 °C (113 °F to 131 °F) but could reach 58 °C
(136.4 °F))
AIR PRESS Reagent air pressure in the reagent bottles (ideally
3.95 to 4.10 psi)
LED DUTY CYCLE Depends on condition of colorimeter cell and age of
analyzer (typically 7,200 to 40,000 counts)
HEATER DUTY
CYCLE Percentage of time the colorimeter heater is on to
maintain a constant 50 °C (122 °F)
SAMPLE FLOW Approximate sample flow into the colorimeter,
measured during the flush cycle
SAMPLE PRESS 1 Sample pressure before the pre-heater block (ideally
2 to 4.5 psi depending on incoming sample pressure)
SAMPLE PRESS 2 Differential pressure measured across the sample pre-
heater during a colorimeter cell flush. Slightly less than
SAMPLE PRESS1 during the flush cycle and zero when
the flush is off.
REAGENT 1 Level of reagent remaining
REAGENT 2 Level of reagent remaining
REAGENT 3 Level of reagent remaining
STD SOLUTION Level of standard solution remaining
FAN SPEED The speed of the ventilation fan.
LEAK COUNTS Indication of possible fluid leaks (range 0 to 1023). A
count of over 511 indicates a fluid leak
