calibration. User calibration is recommended only if you must conform to a standard
operating procedure or if the conductivity cell has undergone physical change (e.g.,
deposits on conductivity cell walls that cannot be removed or physical damage to the
conductivity cell walls).
1. Fill the calibration cup to the fill line with approximately 130 mL of the desired
