Page 6: Introduction
Chapter 1 Introduction The Aqua-Check Water Analyzer is a compact, rechargeable, battery-operated, field instrument that simultaneously measures the dissolved oxygen level, pH, conductivity, and temperature of water and aqueous solutions. The operator can elect to display either uncompensated values or values that have been compensated for external effects. -

Page 12: Preparing The Dissolved Oxygen Sensor
Chapter 3 Operation This chapter describes the basics of taking a measurement with the Water Ana- lyzer. Refer to Figures 2.1 and 2.2 in Chapter 2 when necessary. Removing the pH Boot Before a measurement can be made, the boot must be removed from the pH sensor. The boot is a small polyethylene capsule that covers the pH sensor. -

Page 14: Storing Readings
Storing Readings Pressing the [STORE] key while the Water Analyzer is displaying readings will result in the data being stored in the measurement log. The numbered location assigned to the logged reading will appear on the display, near the temperature readout, for about three seconds. -
Page 15: Oxygen Display
Water Analyzer and an older, less sophisticated oxygen meter is required. If “Automatic Ox Cal.” is selected, you will be asked to specify the atmospheric pressure when calibrating the dissolved oxygen sensor (see “Dissolved Oxygen Aqua-Check Water Analyzer Operator’s Manual Rev. 2.1... -
Page 16: Conductance Display
Sensor Calibration” in this chapter). The Water Analyzer will calculate the appro- priate value for the oxygen concentration based upon the water’s temperature and the specified pressure. Once the desired selection is displayed, press either the [ENTER] or the [STORE] key to record the choice and advance to the conductance prompt. -

Frequently, the factory calibration will suffice for the life of the sensor; this is especially true if you are working with only slightly conductive (less than 5 mS/cm) solutions. Aqua-Check Water Analyzer Operator’s Manual Rev. 2.1... -
Page 18: Temperature Sensor Calibration
Each of the four sensors in the probe (dissolved oxygen, pH, conductivity, and temperature) are calibrated separately. When calibrating, allow the probe to sit in the solution for 5 minutes and then allow up to 10 minutes for the ADC (Analog Digital Conversion ) readout to stabilize. - Page 19 (100% humidity or a given standard solution), press the [STORE] key to complete the dissolved oxygen sensor calibration. To skip this step, press the [ENTER] key and the previous calibration information will be used. Aqua-Check Water Analyzer Operator’s Manual Rev. 2.1...

Page 20: Ph Sensor Calibration
After the dissolved oxygen sensor calibration is complete, the Water Analyzer will resume displaying the four measured parameters: temperature, pH, conductivity, and oxygen. pH Sensor Calibration For maximum accuracy, the pH sensor is calibrated at three points: acid point, base point, and neutral point. 1. -

Page 26: Chapter 4 Maintenance
Chapter 4 Maintenance This chapter describes the maintenance of the Water Analyzer. General Sensor Maintenance The Water Analyzer normally requires only minimal maintenance, aside from periodic calibration. The frequency of required calibration will depend upon the accuracy of the readings desired, the frequency and manner in which the meter is used, and the storage condi- tions. -
Page 27: Dissolved Oxygen Sensor Maintenance
Note: The pH electrode must not be stored dry. If the electrode is allowed to dry, it will be rendered useless and the sensor will have to replaced or returned to the factory for repair. Aqua-Check Water Analyzer Operator’s Manual Rev. 2.1... -
Page 28: Conductivity Sensor Maintenance
Storing the pH electrode in deionized water (or any solution lacking sufficient KCl) will cause the electrode to drift and require increasingly frequent calibra- tion.

Page 30: Chapter 5 Troubleshooting
Chapter 5 Troubleshooting The Aqua-Check Water Analyzer is not designed for field repair. Some problems, however, may be remedied without the need for any physical disassembly. The more common of these and their remedies are listed below. If a problem still exists after reviewing the following chart or if a particular problem is not addressed, contact your dealer or the factory for assistance. - Page 31 Notes Aqua-Check Water Analyzer Operator’s Manual Rev. 2.1...
