Page 11: Powder Reagents
Powder Reagents The powder reagents provided with this product are prepared based on the diethyl-p-phenylenediamine method, a test method used in hygienic chemistry. When a pack of powder reagent is added to test water such as tap water or pool water that contains free residual chlorine, it is colored to between light reddish purple and dark reddish purple. -
Page 12: Using The Product
• Do not use colored powder reagents even within the expiry date. • Open powder reagent packs immediately before use. AQUAB body • When performing measurement, set the control panel surface face up and horizontal. • When inserting the sample cell in the measurement chamber, be sure to align the triangle marks. -
Page 13: Sample Cells
Sample cells (Note 2) • Take care when handling sample cells to prevent them from becoming scratched. • Wipe off dirt from sample cells beforehand. • Use the same sample cell for zero-point calibration and measurement. • If the outside of a sample cell is wet, thoroughly wipe off moisture on the cell. •... -

Page 15: Inserting The Batteries
Memory Check Mode Inserting the Batteries Insert four AAA alkaline batteries into the AQUAB body. Prepare four fresh AAA alkaline batteries. Note: The batteries included with the product are only for checking operation. -
Page 16: Measurement
Fit the four AAA alkaline batteries you have prepared into the battery compartment, making sure that their polarities are facing the correct way. Close the battery cover, and slot a coin or similar object into the groove of the battery lock and tighten it to lock. - Page 17 Quickly wipe off any dirt or water droplets on the sample cell with clean laboratory paper, for example. Note: If the sample cell is wiped with dirty paper, the dirt from that paper will transfer to the sample cell. Be sure to use clean paper.

- Page 18 Concentration Measurement When zero-point recognition is completed, remove the sample cell from the measurement chamber. Add the powder reagent to the test water inside the sample cell, close the cap, and shake the cell thoroughly so that the reagent is dissolved completely. Note: Concentration cannot be measured if zero-point recognition is not completed.

Page 22: User Calibration Mode
User Calibration Mode This product is pre-programmed with a concentration conversion equation before shipment from the factory. Normally, this equation can be used as it is. However, configure a setting in this mode when frequently measuring special samples or when you want to perform measurement using your own setting. - Page 23 Next, load the sample cell containing the solution colored to achieve the target concentration in the measurement chamber while aligning the triangle marks. Pressing the [MEAS.] key displays the final calibration concentration flashes at the same time. Using the [ZERO] and [MEAS.] keys, Display example set the target concentration value.
- Page 24 Hold down the [ZERO] and [MEAS.] Display example keys at the same time for at least 5 seconds. "CLr" appears on the main display and starts flashing. When the main display changes to "---," this indicates that the reset is completed.
