CFA3000 MANUAL APPENDIX
APPENDIX B SPECIFICATIONS
Accuracy: All twodecade ranges up to 1000 ppb
maximum: ±10% of reading or ±2 ppb, whichever is
greater
0.110 ppm range = ±10% of reading or ±0.5 ppm,
whichever is greater
Automatic Calibration: 40 minutes
Total Calibration: 40 minutes, twice/week
Reagent Consumption: 5 L of each reagent per 3
months
Standard Consumption: 1 L of high standard,1 L of
low standard per 3 months
Sample Requirements:
Flow: 4050 mL/min
Current standard bottles are:
“0”(baseline): 1.0 L.
Fullscale: 5.0 L
Pressure: <10 psig (<170 kPa) (overflow cup must
drain to atmosphere)
Temperature: 050° C (32122° F)
Filter: 8 micron filter in sample line is
Recommended; (#180134108).
Multiple Stream Option: General: up to 6 sample
streams; measurement is sequential
Response Time: 15 minutes (methoddependent)
Outputs: 420 mA or 05 Vdc (nonisolated).
(Isolated output is optional.)
Load requirements for 420 mA output: 450 ohms
minimum, 1200 ohms? maximum
Load requirements for 05 Vdc output: 10 k Ohms,
minimum
The range of outputs is the same as the measure
ment range. Parallel output for printer is optional for
single stream, standard for multistream monitors.
RS232C output is optional for single stream monitors,
standard for multistream monitors.
Alarms:
General: contact closures for
• leak detection,
• calibration in progress,
Contact closures are rated:2 A at 250 Vac or 3 A
at 30 Vdc; delay on/off is 1 minute
Streams 2 through 6 (multistream option):
• One alarm relay for each stream; contacts have
dc ratings
• 100 Vdc (maximum carry only)
• 0.5 A (maximum switched)
• delay on/off time is 1 minute
Display: Single line LCD, 4 1/2 digits, readout in
concentration units. For multistream option display
remains at last value until new stream reading is stable.
Status LEDs:
• Leak,
• Lamp failure,
• Quarterly maintenance due
• Calibration in progress.
For multistream analyzers.
StatusLEDs show:
• the sample stream currently selected
• the sample stream for which data is being
displayed.
Environmental: The analyzer is not intended for out
door use. Install in a clean, indoor environment.
Ambient Temperature:
40120° F (1045° C) must be regulated to ± 10°
within range, avoid temperature swings
greater than ± 10° F (± 5± C) over a 12hour period
Humidity: 595% (noncondensing)
Pollution degree: Standard
Altitude: Not applicable
