Instruction Manual Alpha-COND 550 3. Operation 3.1 Measurement mode When the conductivity monitor 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 monitor is in measurement mode. The upper alpha-numerical display shows the measured conductivity value, while the lower display shows the temperature value.

Instruction Manual Alpha-COND 550 4. Calibration Mode 4.1 About Calibration Calibration should be carried out each time a new electrode is attached to the monitor or when you suspect that the monitor/electrode is out of calibration. The monitor allows you to perform temperature calibration and conductivity calibration.
Instruction Manual Alpha-COND 550 4.2 Calibration The monitor requires one-point calibration. Conductivity calibration is always carried out in the specific measuring range selected for the monitor. Make sure, the monitor is set to desired measuring range before you enter calibration mode (Refer Section 5.4 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 monitor.
Instruction Manual Alpha-COND 550 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. • If the conductivity reading of the solution is not within 10% to 100% of the full scale of the selected measuring range, calibration error occurs; LCD displays “ERR” and flash electrode annunciator.
Instruction Manual Alpha-COND 550 5. Setup Mode 5.1 Enter Setup mode The setup mode allows you to customize the settings of the conductivity monitor 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).
Instruction Manual Alpha-COND 550 5.3 Temperature Settings Automatic Temperature Compensation (ATC): The conductivity value of a sample is affected by temperature. Use ATC feature of the monitor to compensate for conductivity changes when the temperature of the sample or process liquid fluctuates. Connect a separate temperature probe (Pt100/pt1000) to the monitor if an integrated conductivity/Temperature probe is not available.
Instruction Manual Alpha-COND 550 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. Place a thermometer, which is known to be accurate, in your sample or process liquid. Make sure your temperature probe is placed in the same liquid.
Instruction Manual Alpha-COND 550 5.4 Measuring Range Settings The conductivity monitor has 5 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 monitor behaves in the measurement mode and calibration mode.

User configured values remain active, when confirmed by pressing ENT key.
Instruction Manual Alpha-COND 550 5.6 Viewing Electrode Properties Each time you calibrate the conductivity sensor, the monitor re-calculates the calibration factor of the sensor and shown in the LCD at the end of calibration. The setup mode allows you to view the last saved calibration factor and cell constant at any time. 2 1 SETUP HOLD 1 ENT SETUP ENT HOLD SETUP ENT HOLD From measurement mode press ENT key to enter setup mode as described in section 5.1.
