Notes: to exit from ph calibration mode without confirming calibration, Do Not press Enter in step 6. Press CAL/ MEAS insteadConductivity calibration the pc 300 meter has five measuring ranges. You can calibrate one point in each of the measuring ranges( up to five points ) if you are measuring values in more than one range, over-ride existing stored calibration data for each measuring range you calibrate.If you are measuring in ranges near to or greater than 20ms(10ppt) ,or near to or lower than 100 calibrate the meter at least once a week to get specified +1%If you are measuring in the mid ranges and you washed the probe in deionised water and stored it dry, calibrate the meter at least once a month. If you take measurements at extreme temperatures, calibrate the meter at least once a weekPreparing for conductivity calibrationFor best results, select a standard value close to the sample value you are measuring. Alternatively use a calibration solution value that is approximately 2/3 the full-scale value of the measurement range you plan to use. For example, in the 0 to 1999 us conductivity range use a 1413 us solution for calibration
