L tag is displayed on the left lower corner of the LCD After measurements switch the meter off by pressing the ON OFF key The OFF mes sage appears on the LCD release the button Store the electrode with a few drops of stor age solution in the protective cap Note We reserve the right to modify design construction and appearance of our products with out advance notice TAKING pH MEASUREMENTS e Always remove the electrode protective cap before taking any measurement If the electrode has been left dry soak the tip bottom 2 5 cm in M10000 rinse solution for a few minutes to reactivate it e Select the pH range with the RANGE key e Immerse the tip 2 5 cm of the probe into the sample and stir gently e Read the pH value when the clock symbol stops blinking pH CALIBRATION PROCEDURE A Preparation Buffer solutions 1 pH 7 01 6 86 MA9007 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 beaker for rinsing the probe the other for calibration In this way the cross contamina tion between solutions is minimized B Procedure Enter the pH mode with the RANGE key Select the 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
5. TDS OPERATIONS e The user can select the EC TDS conversion factor CONV value as well as the B coef ficient BETA for automatic temperature com pensation e Enter the EC or TDS mode with the RANGE key then press and hold the ON OFF key until TEMP is displayed on the secondary LCD Press this key AG 5 again to show the current con TONY version factor CONV e Press the SET button to change the value then press again this key to show the cur rent temperature coefficient BETA e Press the SET button to change the value then press the ON OFF key return to normal operation e For taking EC or TDS measurements immerse the probe in the solution to be tested e Select either EC or TDS mode with the RANGE key e Stir gently and wait for the reading to stabi lize the clock symbol stops blinking EC TDS CALIBRATION PROCEDURE e Clean the probe with M10000 solution Enter the EC mode with the RANGE key e Immerse the probe in MA9030 12 88 mS cm calibration solution e Press and hold the ON OFF key until CAL is displayed on the LCD Release the bution _ ic and the message 12 88 mS is nak USE will appear e The meter will perform automatic calibration and then display OK for 1 second before returning to normal mode e The calibration is now complete and the CAL tag is displayed on the LCD to indicate that th
