[. . . ] Instruction Manual PC 10 Waterproof Hand-held pH/Conductivity/Temperature Meter 68X230401 Rev 5 08/04 Technology Made Easy . . . Preface This manual serves to explain the use of the Waterproof PC 10 hand-held meters. It functions as a step by step guide to help you operate the meter and as a handy reference guide. It is written to cover as many anticipated applications of the Waterproof PC 10 meters as possible. If there are doubts in the use of this meter, please do not hesitate to contact the nearest Authorised Distributor. [. . . ] Since temperature readings affect the accuracy of the pH and conductivity measurements, it is strongly recommended to carry out pH and conductivity calibration after a temperature calibration is done. Figure 10: CONFIRM temperature calibration -9- Instruction Manual PC 10 4. 4. pH Calibration This instrument is capable of up to 3-point pH calibration to ensure accuracy across the entire pH range of the meter. You can perform 1, 2, or 3 point calibration with standard pH buffers of 4. 01, 7. 00 and 10. 00. We recommend that you perform at least 2-point calibration using standard buffers that covers the expected sample range. You can also perform a 1-point calibration, but make sure that the buffer value is close to the sample value you are measuring. This meter features three pre-programmed pH buffers (pH 4. 01, 7. 00 and 10. 00). These indicators also flash if the buffer used is not the same as the buffer value on the secondary display. calibration is complete, press Figure 14: Next calibration point Figure 13: CONFIRM calibration point or key to select the next buffer value you want to calibrate (pH 4. 00, 7. 00 CAL/MEAS to return to pH measurement - 11 - Instruction Manual PC 10 4. 5. Conductivity Calibration The Important Information on Conductivity Calibration Your meter has four measuring ranges. You can calibrate one point in each of the measuring ranges (up to four points). If you are measuring values in more than one range, make sure to calibrate each of the ranges you are measuring. The following table lists the corresponding conductivity range. You should calibrate each range using a solution that falls between the values in the "recommended calibration solution range" column. Conductivity Range 0. 00 to 19. 99 µS 0. 0 to 199. 9 µS 0 to 1999 µS 0. 00 to 19. 99 mS Recommended Calibration Solution Range 6. 00 to 17. 00 µS 60. 0 to 170. 0 µS 600 to 1700 µS 6. 00 to 17. 00 mS NOTE: Minimum calibration value should be 20% of full scale for the specific range. E. g. : The LOWEST calibration value for the range of 0. 00 to 19. 99 µS is 4. 00 µS. When you recalibrate your meter, old calibrations are replaced on a range basis. For example, if you previously calibrated your conductivity meter at 1413 µS in the 0 to 1999 µS range and you recalibrate at 1500 µS (also in the 0 to 1999 µS range), the meter will replace the old calibration data (1413 µS) in that range. The meter will retain all calibration data in other ranges. To completely recalibrate your meter, or when you use a replacement probe, it is best to clear all calibration data in memory. To erase all the old conductivity data, see Section 4. 1: Important Information on Meter Calibration. NOTE: These meters are factory set to a temperature coefficient of 2. 00% per °C. For most applications this will provide good results. The factory default value for normalization temperature is 25°C. - 12 - Instruction Manual PC 10 4. 6. 1. Calibrating for Conductivity: Pour out two separate portions of your calibration standard and one of DI water into separate clean containers. READY mS MEAS 2. If necessary, press MODE key to select Conductivity Mode. The µS and mS indicator will appear on the right side of the display. Rinse your probe with DI water, then rinse the probe in one portion of the calibration standard. [. . . ] A C C E S SO R I E S 11. 1.
