2. If the module is functioning correctly, check for any knots or kinks in the tube and ensure there is enough cleaning fluid in the bottle. |
| The needle cannot inject the solution into the sampling cup | 1. Check the valve on the diluter.
2. Confirm there is sufficient cleaning solution in the bottle.
3. Inspect all pipe connections for leaks or blockages.
4. Clean the suction needle if it's dirty or replace it if it's scratched. |
| The sample size is 5 µL. Measurement repeatability is poor. The volume of the inhalation cuvette is incorrect | 1. Check if the cuvette is clean.
2. The needle may be dirty or clogged; clean or replace it as needed.
3. Inspect the tubing for knots or blockages.
4. Verify the operation of the aspiration needle.
5. Ensure the needle is positioned correctly. |
| The flushing cup cannot be emptied even if the peristaltic pump is working properly | 1. Check the tubing from the flushing cup to the solenoid valve for knots or improper connections.
2. Test the electric switch valve.
3. Inspect the silicone tube in the peristaltic pump for kinks; replace if necessary.
4. Examine the entire pipeline of the peristaltic pump. |
| The instrument cannot be automatically zeroed. At reset, the voltage is too low | 1. Fill the cuvette with water if it is empty.
2. Check if the peristaltic pump is operating correctly and inspect the tubing.
3. Ensure the distilled water being aspirated is correct.
4. Check if the rinse bottle is empty and refill if necessary.
5. Test the solenoid valve of the peristaltic pump.
6. Replace the bulb if it is old or damaged.
7. Adjust the amount of liquid absorbed; the volume may be too high or too low.
8. Clean the cuvette or remove bubbles if present. |
| QC results are out of range (reference methodology) | 1. Confirm that quality control is performed according to the manufacturer’s instructions.
2. Ensure settings like wavelength, temperature, sample type, sample size, and reagent amount are correct.
3. Check for other influencing factors such as reagent stability.
4. Use double-distilled or deionized water for preparation of reagents and quality control solutions. |
| Kinetic measurement of light is the result of GOT or GPT being low | 1. Verify that reagents, controls, and standards are within their expiration dates.
2. Use the recommended cleaning agent instead of just distilled water.
3. Rinse the cuvette or replace the reagent cup if contamination is suspected.
4. Double-check the factor used, as well as temperature and volume settings.
5. Review the inspection procedures, including water, reagents, quality control serum, and cleaning solutions.
6. Confirm that the wavelength is set correctly.
7. Replace the reagent if it has expired or is not fresh. |
| The suction arm moves down but cannot aspirate | 1. Replace the silicone tube of the peristaltic pump if it is worn out.
2. Adjust the tightness of the peristaltic pump runner.
3. Check if the aspiration needle is blocked or disconnected.
4. Inspect for any damaged components that might be causing the issue. |
