[. . . ] Instruction Manual 24-hour Continuous Field Monitors pH, ORP, and Conductivity 68X254901 Technology Made Easy . . . Rev. 5 08/03 Preface This manual serves to explain the use for all models of the Field Monitors for pH, ORP, and Conductivity (each model sold separately). If there are doubts in the use of this meter, please do not hesitate to contact the Authorized Distributor. Eutech Instruments/ Oakton Instruments cannot accept any responsibility for damage or malfunction to the meter caused by improper use of the instrument. [. . . ] Be sure to remove the protective electrode storage bottle or rubber cap of the probe before calibration or measurement. If the electrode has been stored dry, wet the probe in tap water for 10 minutes before calibrating or taking readings to saturate the ORP electrode surface and minimize drift. Do not reuse calibration solutions after calibration. Dispose of any used calibration solution. Contaminants in the solution can affect the calibration, and eventually the accuracy of the measurements. IMPORTANT: ORP offset adjustment is limited to ±100 mV from the original reading. NOTE: All new calibration data will over-ride existing calibration data. 5 5. 2 ORP Calibration 1. The monitor will Immerse ORP electrode into a calibration standard solution, be in ORP measurement mode. for example, 255 mV 2. Rinse the probe thoroughly with de-ionized water or a rinse solution. Do not wipe the probe; this causes a build-up of electro-static charge on the surface. Dip the probe into the calibration standard. The end of the probe must be completely immersed into the sample. Let probe soak 2 to 5 minutes or until readings stabilizes. Press the CAL key to enter the calibration mode. "CA" will flash on the display for a second and then a value close to the calibration standard will flash. Press the or keys to adjust the display to match the calibration standard value. "CO" will flash on the display. The reading should now display the same value as the calibration standard. See Figure 3. Press Press Press Figure 5 - ORP Calibration Procedure 6 6 CONDUCTIVITY CALIBRATION This section is applicable for the following models: Description Conductivity FMCON 1 with Conductivity electrode and 110/120 VAC power adapter. "CA" will flash on the display for a second and then a value close to the calibration standard will flash. Press the or keys to adjust the display to match the calibration standard value. "CO" will flash on the display.
