Preface
This manual serves to explain the use of the Alpha COND 500 transmitter. [. . . ] 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.

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.

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
The reset function lets you choose to either reset the transmitter's conductivity calibration only or conductivity calibration plus all setup functions that you might have changed back to factory default settings. 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. [. . . ]
