Page 8: About This Product
About This Product This product is an easy-to-use handy water Easy-to-carry, compact body meter. The test water is colored with a reagent, and the concentration of residual chlorine Saves up to 99 measurement values is measured by the amount of transmitted light. - Page 9 Function of Operation Keys Name Function When this key is pressed in the measurement mode, zero-point recognition is started. [ZERO] key In the memory check mode or user calibration mode, it functions as the up key. When this key is pressed in the measurement mode, measurement of the test water is started.

Display There is sufficient battery power left. The remaining battery power is approximately 50 %. The batteries have run out. Replace with new batteries. No. Name Description This displays measurement values, various setting values, error Main display messages, and other information. In this water quality photometer, concentration is displayed in terms Unit display of mg/L. -
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 14: Mode Selection
Mode Selection When using this product, select a mode according to the purpose to perform the intended work procedure. Select one of the three modes: measurement mode, memory check mode, and user calibration mode. To change the mode, you can use the mode selection screen or press the [MODE] key. Changing the Mode on the Mode Selection Screen Holding down the [MODE] key for at least 2 seconds enters the mode selection screen. -
Page 15: Inserting The Batteries
Inserting the Batteries Insert four AAA alkaline batteries into the AQUAB body. Prepare four fresh AAA alkaline batteries.

Slot a coin or similar object into the groove of the battery lock and turn it to loosen. -
Page 16: Measurement
Measurement This section describes measurement procedures. Before starting measurement, be sure to thoroughly read "Safety Precautions" and "Measurement Precautions." Turning the Power ON With the display OFF, press any key Display example to turn the instrument ON. The measurement mode is used immediately after the power is turned ON. - Page 17 [ How to close the cell cover ] Close the cell cover, and press the Sample cell [ZERO] key. After zero-point recognition for 2 seconds, "0.00 mg/L" and "ZERO" are displayed. This completes "zero-point recognition." Concentration Measurement When zero-point recognition is completed, remove the sample cell from the measurement chamber.

Page 21: User Calibration Mode
User Calibration Mode This water quality photometer 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 22 Next, load the sample cell containing the prepared colored solution equivalent to 2.00 mg/L 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 23 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.
