NOTE: It is necessary to either use an external PT100 temperature sensor for compensation or terminate with a resistance corresponding to the PT100 resistance value at room temperature. The equipment is supplied with a termination resistance for 25˚C.
CALIBRATION PROCEDURE: (At room temperature)
  1. Power on the Instrument ( Ensure Power supply Terminal connection Properly L-Phase ,N-Nutral ,E-Earthing)
  2. Connect pH Electrode at B & C connector
  3. Wash the electrode with distilled water & clean properly.
  4. Deep the Electrode in Standard Buffer Solution of 7.0 pH (Nutral Value)
  5. Check the reading for 7.00 pH , if there is difference adjust the trim pot mark as 7 pH
  6. Wash & Clean the pH electrode & deep in to 4.00 pH (Acidic value)
  7. Check the reading for 4.00 pH , if there is difference adjust the trim pot mark as 4 pH
  8. Wash & Clean the pH electrode & deep in to 9.20 pH  (Alkaline value)
  9. Check the reading for 9.20 pH ,  it will show correct value within accuracy
  10. Wash the electrode with distilled water & clean properly.
  11. After Calibration Instrument is ready for Use.
NOTE:-For Alkaline value Calibration use standard Buffer of 9.2 pH. For Calibration use trim pot mark as 4 pH


Range: 0 to 14pH
