5. INSTALLATION DETAILS
5.1 Terminal Details:
5.3 Operating Procedure:
Connect Instrument to 230V AC, on back panel. Connect pH & pt100 to their respective connectors
Remove Protective cap of the Sensor containing the storage solution (3.8 Molar KCL). Wait for some time. The
Instruments processor is ready for working.
Note: Save the Sensor cap for future use as a storage container and bulb protector when sensor is not in
service. We recommended 3.8M KCL, as the storage solution.
5.4 Preparation of Standard buffer solution:
For chemical analysis it is necessary to calibrate a pH meter with Sensor. On standard buffer solution of 7
pH, 4 pH, 9.2 pH as per your application. Buffers tables are available with chemical suppliers in tables.
Powder or capsule from Dissolve one tablet thoroughly in 100ml distilled or D.M water. Never use tap
water. Store this solution in double cover type bottles. It is supplied to instruments. Mark your date on it.
Note: buffer solution deteriorates after two weeks. Now prepare fresh solution. Always keep buffer solution
in cool place (Do Not Freeze)
5.5 Key Details:
PROGRAM KEY: - This key is used to Calibration and setting of set points.
INCREMENT KEY: - This key is used to 1) See the Temperature / setting of Temperature.
2) Increment the numerical value of any digit,
from 0 to 9, by one at each time.
SHIFT KEY: - This key is used to 1)See the Value of Set points.
2) Shift the cursor to the next digit.
ENTER KEY: - This key is used to 1) Validate the function or value of parameter.
2) See the SLOP
6. CALIBRATION PROCEDURE
Note :
6.2 Temperature Compensation
When RTD PT 100 Temperature Sensor is connected, pH Indicating Controller Transmitter MS pH 97
automatically goes in Automatic Temperature Compensation Mode.
When RTD PT 100 Temperature Sensor is Not connected, pH Indicating Controller Transmitter MS pH 97 is
in Manual Temperature Compensation Mode.
Note: When you are using manual Temp you must set it before taking pH reading.
