Control operations

ON/OFF control

  • Upper and lower limits setting range: 0.00 pH to 14.00 pH
  • Control width: 0.00 pH to 4.00 pH (±0.00 pH to ±2.00 pH)
    Time-division proportional control
  • Upper and lower limits setting range: 0.00 pH to 14.00 pH
  • Proportional band: 0.00 pH to 4.00 pH
  • Cycle time: 5 s to 300 s
  • Control output shift capability: 0% to 50% of shift volume for the cycle time
  • Self-extending cycle time capability: The cycle time is extended automatically when the deviation value enters a set range (F zone) in proportion to the deviation value (This feature has no effect when the shift function has been enabled).
  • F zone: 1% to 100% of the proportional band (Self-extension of the cycle time starts working when the deviation enters the above range).
  • Upper limit for extending the cycle time: 0 s to 300 s.
  • Maximum control volume: 50% to 100% (To be applied regardless of whether the measured value is in the proportional band or not).
Calibration function 2 points automatic calibration or manual calibration.
2 points automatic calibration: with automatic validation of the electrode
characteristics.
  Types of standard solution: pH 2, pH 4, pH 7, pH 9 and pH 10 (JIS)
  Combination of standard solutions: pH 7 and one of the others
  Manual calibration: Freely selectable, but the difference should be over 2 pH.
Temperature calibration (one point).
