| 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) |
- Power on the Instrument ( Ensure Power supply Terminal connection Properly L-Phase ,N-Nutral ,E-Earthing)
- Connect pH Electrode at B & C connector
- Wash the electrode with distilled water & clean properly.
- Deep the Electrode in Standard Buffer Solution of 7.0 pH (Nutral Value)
- Check the reading for 7.00 pH , if there is difference adjust the trim pot mark as 7 pH
- Wash & Clean the pH electrode & deep in to 4.00 pH (Acidic value)
- Check the reading for 4.00 pH , if there is difference adjust the trim pot mark as 4 pH
- Wash & Clean the pH electrode & deep in to 9.20 pH (Alkaline value)
- Check the reading for 9.20 pH , it will show correct value within accuracy
- Wash the electrode with distilled water & clean properly.
- 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 |
