FUNCTIONAL DESCRIPTION

Liquid Crystal Display
On/Off button

OPERATION

Press the On/Off button to turn the tester on. All segments are displayed for a few seconds followed by “Add”, and “C1” with “Press” blinking.
Fill the cuvette with 10 mL of unreacted sample and replace the cap. Place the cuvette into the tester and close the cap.
Press the On/Off button. When the display shows “Add”, and “C.2” with “Press” blinking, the tester is zeroed.
Remove the cuvette, unscrew the cap and add the content of one packet of MI512-0 reagent. Replace the cap and shake gently for 2 minutes until the powder is completely dissolved. Replace the cuvette with the tester.
Press and hold the On/Off button. The display will show the countdown prior to the measurement. Alternatively, wait 3 minutes and press the On/Off button.
When the timer ends the tester will perform the reading. The tester directly displays the concentration of phosphate in ppm.

The tester automatically turns off 2 minutes after reading.

BATTERY REPLACEMENT

To save the battery, the tester shuts down after 10 minutes of non-use and 2 minutes after reading. A fresh battery lasts for a minimum of 5000 measurements, depending on the light level.

When the battery capacity is under 10 %, the tester displays “bAt” at start-up.
When the battery is drained the tester displays a “bad” and then “bAt” message.
Replace the battery with a new one and restart the tester.

To replace the battery, follow the steps:

Press the On/Off button to turn the tester off.
Turn the tester upside down and use a screwdriver to unfasten the screw and remove the battery cover.
Remove the old battery and replace it with a fresh 1.5V AAA battery, inserting the negative end first.
Replace the battery cover, fasten and tighten the screw.
