Test Solution - test for calibration of 110 ml meters

Manual

1. First of all, before proceeding to check / calibration of the meter, replace the battery on a new one.

2. Measurement part of the meter (electrodes, temperature sensor) before starting the measurement must be completely clean and dry. The meter electrodes can not have sediments or other dirt.

3. Bring the Solution test solution to a temperature of 25 o C ± 0.2 o Preferably, it is preferably to check the temperature with any exact thermometer.

4. Immerse the measuring part of the meter in solution. Move a few times a meter, paying attention to in the measurement part there were no air bubbles. Wait a few minutes to fix the temperature on the meter display

5. Check the meter's indications. If the meter indication at 25 o C ± 0.2 oC is within 240-260 US value can be considered as correct. Otherwise, make calibrations according to the meter's instructions.

6. After completing / calibration, the measuring part of the meter thoroughly rinse under running water and then in water.

Caution! It is absolutely noted to pay attention to check / calibrated meter was dry and did not contain water traces. Otherwise, you can pollute the Solution Solution solution which will result in incorrect calibration and erroneous indicators of the meter. The accuracy of the Solution test is approx. 4%. During checking / calibration, the Solution test solution must be at least as thoroughly with a temperature of 0.2 oC.

Caution! Protect from children. If you need to seek medical advice, show the container or label. Do not use plants and animals intended for consumption and food processing. Preparation designed for aquariums with shrimps, fish and decorative plants.
