10 MAINTENANCE
For a long lifetime and reliable measurements we advise the following:
- Store the instrument in a dry room.
- Do not expose the instrument to high temperature changes (because of condensation).
- To clean the outside of the instrument, use a moisten cloth.
- Clean the electrodes after measurement always with distilled water.
- Protect the pH-electrode against desiccation by storing it always in storage liquid.
- Protect instrument and electrodes against high shocks and dirt.
11 STABILITY CHECK
When in automatic calibration, the instrument will check for a stable reading of the measuring value.
A pH reading is considered stable by the instrument when the difference between 4 readings tested from
1 to 8 seconds is less then 0,01 pH.
A EC reading is considered stable by the instrument when the difference between 4 readings tested from
1 to 8 seconds is less then 0,025 mS.
