1. Press and hold the ON OFF key until CAL is displayed on the lower LCD Release the ETa button and the message 7 01 pH USE or 6 86 pH USE for NIST buffer set will be dis Played For a single point pH calibration place the probe in any buffer fromthe selected set e g PH 4 01 or 7 01 6 86 or 10 01 9 18 The meter will auto matically recognize the buffer value store the calibration point and reum to normal node If using pH 7 01 or pH 6 86 after recognition of the buffer press the ON OFF button to retum to nonmel node For a two point pH calibration place the probe in PH 7 01 buffer or pH 6 86 if the NIST buffer set wes selected The neter will recognize the buffer value and then display pH 4 01 USE Place the probe in the second buffer pH 4 01 or 10 01 or if using NIST pH 4 01 or 9 18 When the second buffer is recognized the LCD will display OK for 1 second and the meter will retum to normal node The CAL tag is displayed on the LCD to indicate that the meter is calibrated EC TDS OPERATIONS The user can select the EC TDS conversion factor CONV as well as the B coefficient BETA for autorratic tenqperature compensation Enter the EC or TDS rrode with the RANGE key then press and hold the ON OFF key until TEMP is displayed on the secondary LCD Press this key again to show the current conversion fac tor CONV Press the SE2. appears on the LCD release the button Store the electrode with a few drops of storage solution in the protective cap TAKING pH MEASUREMENTS Always remove the electrode protective cap before taking any nreasurerrent If the electrode has been left dry soak the tip bottom 2 5 an in M10000 rinse solution for a few minutes to reac tivate it Select the pH range with the RANGE key Intrerse the tip 2 5 cn of the probe into the sample and stir gently Read the pH value when the dock symbol stops blinking PH CALIBRATION PROCEDURE A Preparation Buffer solutions 1 pH 7 01 6 86 IMA9007 MA9006 2 pH 4 01 MA9004 for acidic calibration pH lt 7 or pH 10 01 9 18 MA9010 MA9009 for alkaline range pH gt 7 Use two beakers for each buffer solution one bea ker for rinsing the probe the other for calibration In this way the cross contamination between solutions is minimized B Procedure Enter the pH mode with the RANGE key Select calibration buffer set press and hold the ON OFF key until the LCD shows TEMP Press again this key and the BUFF message will appear then select the desired buffer set with the SET key 7 01 pH BUFF for standard solutions pH 4 01 7 01 10 01 or 6 86 pH BUFF for NIST solutions pH 4 01 6 86 9 18 Press ON OFF again to exit Rerrove the protective cap then intrerse the probe in the first buffer solution
