7. Troubleshooting
This section provides solutions to common issues you may encounter with your Hach 2100Q Turbidimeter.
| Problem | Possible Cause | Solution |
|---|---|---|
| Instrument does not power on. | Dead or incorrectly installed batteries. | Check battery polarity; replace batteries. |
| Inaccurate or inconsistent readings. | Dirty sample cell; air bubbles in sample; instrument needs calibration; scratched sample cell. | Clean sample cell thoroughly; degas sample; perform calibration; replace damaged sample cell. |
| Display shows "Error" message. | Measurement outside range; internal fault. | Ensure sample is within 0-1000 FNU range. If error persists, contact Hach support. |
| Confusion between FNU and NTU. | Misunderstanding of measurement units. | The Hach 2100QIS01 model measures exclusively in FNU (Formazin Nephelometric Units) using an LED light source. It does not measure in NTU (Nephelometric Turbidity Units). Ensure your application requires FNU measurements. |
