Measurement
Maintenance and storage
For protein deposits the manufacturer recommends an enzyme cleaning solution (2964349). Do not use organic solvents.
Battery replacement
Always dry the meter first.
Reference electrode replacement
Avoid direct contact with the pH sensor.
When the liquid in the reference electrode is decreased, replace the electrode (9316900).
Troubleshooting
| Error code | Definition |
| Battery icon | <10 hours battery life |
| BAT | Replace the battery. |
| 0.00 or 14.00 | Make sure that the probe is properly immersed in the sample. |
| E06 | Slope error. |
| E07 | Voltage error. |
| E08 | Calibration time out. |
| E13 | Temperature sensor error. |
Note: When an error occurs, clean the probe and calibrate again. If the problem is not solved, contact Technical Support.
