Visual Inspection: Routinely inspect the lower electrode chip for any signs of wear, damage, or contamination. Look for cracks, chips, or deformation, as these can affect the chip’s ability to function correctly.
Surface Condition: Ensure that the surface of the electrode is clean and smooth. Any buildup of residue or oxidation can interfere with the conductivity and performance of the chip.
Conductivity Check: Periodically check the conductivity of the electrode to ensure it is functioning optimally.
Visible Damage: Replace the lower electrode chip if you observe any visible cracks, chips, or other structural damage that could impair its function.
Decreased Performance: If the instrument starts to show inconsistent or inaccurate results, especially after ruling out other potential causes, it may be time to replace the electrode chip.
Frequent Cleaning Needs: If the chip requires more frequent cleaning or shows rapid buildup of residues, it might be an indication that the chip is nearing the end of its usable life.
