Slow Response; Analog Output Doesn't Agree With Display Concentration - Teledyne 6200A Manual

TAI Model 6200A SO

9.2.11 Slow Response

Contaminated or dirty sample delivery pneumatics
A. Dirty/plugged sample filter or sample lines.
B. Dirty reaction cell.
C. Check leak.
1. Flow rate too low.
2. Wrong materials in contact with sample - use glass or Teflon.
3. Insufficient time allowed for purging of lines upstream of analyzer.
4. Insufficient time allowed for SO

9.2.12 Analog Output Doesn't Agree With Display Concentration

1. V/F board DAC's out of calibration. Do DAC calibration and Factory Calibration.
2. Analog outputs electrically loaded down causing voltage to sag. Could be due to input
impedance of chart recorder or data logger being too low or improper grounding.
