2.5 Display & Keypad 2.5.1 Display Overview The Liquid Crystal Display (LCD) of Alpha COND 560 conductivity controller has two alpha-numerical displays (Upper and a Lower). • Upper display: Measured conductivity value is displayed when the controller is in normal operation (measurement) mode. • Lower display: Measured temperature value is displayed when the controller is in normal operation (measurement) mode. In conductivity calibration mode, measured conductivity values are displayed here.
Mode Indicators MEAS Measurement mode (Refer Section 3.1 ) SETUP Setup mode (Refer Section 4.1) CAL Calibration mode (Refer Section 4) Status Annunciators READY Appears when the reading is stable HOLD Appears in Setup mode and Calibration mode to indicate that the relay function is frozen ATC Appears when Automatic Temperature Compensation (ATC) is enabled. Not visible when Manual Temperature Compensation (MTC) is enabled. Flashes if the temperature probe is faulty in its ATC mode.

3 OPERATION 3.1 Measurement mode When the conductivity controller is powered on, the display shows all the LCD segments briefly, and then automatically enters into the measurement mode. MEAS µS READY 25.0 °C ATC The mode indicator ‘MEAS’ at the top of the display indicates that the conductivity controller is in measurement mode.

4 4.1 CALIBRATION MODE About Calibration Calibration should be carried out each time a new electrode is attached to the controller or when you suspect that the controller/electrode is out of calibration. The controller allows you to perform temperature calibration and conductivity calibration. About Temperature Calibration It is important to ensure that temperature calibration is carried out prior to conductivity calibration since temperature readings affect the accuracy of conductivity measurements.
4.2 Calibration The controller requires one-point calibration. Conductivity calibration is always carried out in the specific measuring range selected for the controller. Make sure, the controller is set to desired measuring range before you enter calibration mode (Refer Section 5.6 for selecting measuring ranges). Select a suitable standard conductivity solution so that its conductivity value is within 10% to 100% of the full scale of the selected measuring range of the controller.
uncalibrated (default) reading of the solution. The buffer annunciator appears in LCD. The ‘READY’ annunciator appears when the reading is stable. Once the reading stabilizes press the ▲ or ▼ key to adjust the upper display value to that of the standard solution. Press the ENT key to accept the value. NOTES: The acceptable calibration window is ±40% of the displayed (default) value. For example, if the display is 1000 µS, the values to which it can be adjusted is 600 to 1400 µS.
5 5.1 SETUP MODE Enter Setup mode The setup mode allows you to customize the settings of the conductivity controller to suite your requirements. While in measurement mode, press the ENT key to access setup mode. LCD shows ‘SETUP’ mode indicator and the first page of setup (rAng – Range settings). Press ▲ or ▼ key to access other pages of the setup mode.

The LCD shows the first screen of setup mode (rAng).
5.3 Temperature Settings Automatic Temperature Compensation (ATC): The conductivity value of a sample is affected by temperature. Use ATC feature of the controller to compensate for conductivity changes when the temperature of the sample or process liquid fluctuates. Connect a separate temperature probe (Pt100/pt1000) to the controller if an integrated conductivity/Temperature probe is not available.
Press ▲ or ▼ key to enable (ATC On) or disable (ATC OFF) automatic temperature compensation. Press ENT key to confirm your selection. If ATC enabled (ATC On): 4 Selecting temperature offset: The upper display shows the last configured temperature offset value (if any), otherwise the default is zero. The lower display shows currently measured temperature reading (including last configured offset value). LCD shows ‘ATC’ annunciator in lower-right corner.
5.4 Relay 1/Relay 2 Settings NOTE: If controller type is set to ‘OFF’ (Refer section 5.5 for controller settings), the ‘Relay 1/Relay 2 Setting’ is not available. The SP1 settings determine the operating parameters for Relay 1; while SP2 settings define the operating parameters for Relay 2. Since these two settings have identical setup parameters, only SP1 is described here. Note that when you change measuring range of the controller, the values you have set for SP1 & SP2 will not be affected.
NOTE: 4 This parameter lets you choose the relay function. Select ‘LO’ to activate the relay when the conductivity reading undershoots the set point (SP1) or select ‘HI’ to activate the relay when the conductivity reading overshoots the set point (SP1). SP1 and SP2 can be selected as ‘LO/LO’, ‘LO/HI’, ‘HI/LO’, or ‘HI/HI’. Setting hysteresis value: The lower display shows ‘HYS’. The upper display shows the last configured value, otherwise the default value 20 µS.

If Controller type was set to Off (OFF): The controller reverts to Cntr screen. If Controller type was set to On (L.Ct): 3 Select the relay status under Non-Alarm condition: The lower display shows ‘rEL’. The upper display shows the last configured relay status. (‘dEEn’ or ‘En’). Press ▲ or ▼ key to select the desired relay status. dEEn: De-energized En: Energized Press ENT key to confirm your selection. The controller reverts to Cntr screen.
5.6 Measuring Range Settings The conductivity controller has 6 different measuring ranges. You need to select a range which is the most suitable for conductivity reading of your applications/samples. The factory default is 2000 µS (0 to 2000 µS/cm). The measuring range you select here will affect the way the controller behaves in the measurement mode and calibration mode.

Press ▲ or ▼ key to select the cell type of your conductivity probe. Press ENT key to confirm your selection. NOTE: If you use a 2-cell conductivity sensor, make sure that the pin 1 and 2 are shorted and pin 3 and 4 are shorted on the J10 connector.
Press ▲ or ▼ key to access other setup screens or press ▲ and ▼ key simultaneously (escape) to return to measurement mode. To exit from any intermediate steps, press ▲ and ▼ keys simultaneously (escape). The controller returns to the first screen configuration settings (Cnfg).
5.8 Viewing Electrode Properties Each time you calibrate the conductivity sensor, the controller re-calculates the calibration factor of the sensor and shown in the LCD at the end of calibration.
