[. . . ] Press the ENTER key to confirm the calibration while in calibration mode. pH FM1 Continuous Monitor CAL CAL ENTER ENTER 2. 2 CAL Keys for ORP Monitor The CAL key switches monitor into calibration mode from measurement mode. See page 5 for details. CAL ENTER ENTER Press the ENTER key to confirm the calibration while in calibration mode. The Down/Decrement key scrolls value down in calibration mode. ORP FM1 Continuous Monitor 2. 3 CAL Keys for Conductivity Monitor The CAL key switches monitor into calibration mode from measurement mode. In the calibration mode, pushing CAL key confirms the calibration value and returns to measurement mode. [. . . ] 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. 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. Do not wipe the probe; this causes a build-up of electro-static charge on the surface. "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. 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. The reading should now display the same value as the calibration standard. See Figure 4. into a standard solution, for example, 4 mS Press Press Press Figure 7 - Conductivity Calibration Procedure 8 7 MONITORING Once the monitor is calibrated it is ready for monitoring. See figure below. Mounting Eyelets CAL ENTER pH FM1 Continuous Monitor 8 ELECTRODE CARE AND MAINTENANCE Since your pH/ORP electrode is susceptible to dirt and contamination, clean it every one to three months depending on the extent and condition of use. Depending on the environment and the solution it is immersed in, it may last from 6 to 12 months, or longer. Knowing when to change your pH/ORP electrode usually comes after some experience. It is best to have another pH/ORP tester such as pHScan/ pHTestr 1, Waterproof pHScan/ pHTestr WP2, or ORPScan/ ORPTestr as reference. 8. 1 pH/ORP electrode storage For best results, always keep the pH/ORP bulb wet. Use the protective electrode storage bottle filled with electrode storage solution (0. 1M KCl) or pH 7 for overnight and long term storage. If left dry, soak in tap water or pH 7. 0 buffer solution overnight. 9 8. 2 · · pH/ORP electrode cleaning Salt deposits: Dissolve the deposits by immersing the electrode in tap water for ten to fifteen minutes.
