[. . . ] It is important to ensure that temperature calibration is carried out first prior to conductivity calibration since temperature readings affect the accuracy of conductivity measurements. Your transmitter allows a one point temperature calibration using reference of a thermometer known to be accurate. Please refer to Section 6. 2 - Temperature Compensation Setting for temperature calibration procedure. 5. 3 Conductivity Calibration MEAS A 1-point Calibration is required for this transmitter. If the calibration process is aborted, your transmitter will revert to the previous calibration data. Organize your calibration standard solution in two beakers ­ one for rinsing and the other for calibration. Rinse the electrode in de-ionized water and then rinse with the calibration standard. Dip the electrode to the calibration standard intended for calibration and swirl gently to create a homogenous sample. The upper display will show the measured reading based on the last calibration setting whereas the lower display will show the measured default reading of the standard. Use the or keys to adjust the upper display to the calibration standard value. HOLD 1578 25. 5 S °C ATC CAL HOLD 1578 1578 S 4. CAL 5. Note: You can offset the conductivity reading within ± 40% from the default reading of the standard. The minimum allowable calibration point is 10% of the full scale reading of the range selected. 6. 1413 1578 S Press the ENTER key to confirm the calibration value and to return to the measurement mode. Note: To exit this program without confirming the calibration, press the and keys together (Escape). Note: When there is a calibration error, the buffer icon and ERR annunciator will appear together with a blinking electrode icon. Press both and keys together TWICE to return to the measurement mode. 6 ADVANCED SETUP FUNCTIONS The advanced setup mode lets you customize your transmitter's preferences and defaults. This transmitter features different sub groups that organize all setup parameters. The sub-groups are: 6. 1 Range and Zooming Selection Setting Your COND 500 transmitter provides six selections of conductivity measurement ranges to suit your process application needs. Zooming selection is available where both the 4 mA and 20 mA output current can be assigned to specific conductivity values for a more refined output. Use the or keys to scroll through the six ranges and press the ENT key to select your desired range. The transmitter will now switch to the zooming selection and display the low zoom value setup. SETUP HOLD SETUP HOLD 2. 3. 1. 9 99 1 S NOTE: Range 6 selection page will only appear in the setup mode when the cell constant is selected as K = 1. 0 or K = 10. Range 1 will only appear when cell constant is selected as K =0. 1 or K =1. 0 Six Range selection 4. For zooming setting, use the or keys to set the conductivity low zoom value for the 4 mA current and press the ENT key to confirm. Use the or keys again to set the conductivity high zoom value for the 20 mA current and press the ENT key to confirm and return to the range setup mode. Press both and keys together to return to the measurement mode. SETUP HOLD 0. 00 L S 5.

However, the temperature compensation setting, as in Section 6. 2, will remain unchanged. Use the or keys to scroll till LCD displays `rSt' in the upper display. [. . . ]
