Please read this manual carefully before using the instrument to ensure safe and correct use of the instrument.
On the premise of complying with the principle of use, the service life of the product can be increased, and the operation can be carried out after mastering the various functions and precautions of the instrument to avoid danger.
The following regulations are safety warnings and precautions, which must be followed:
Do not store or work in places with high humidity, high temperatures, or dusty conditions to avoid instrument hardware failure.
During the experiment, personal protection must be done (lab coat, gloves, goggles, masks), and personal safety must be paid attention to when using sulfuric acid.
Instruments and spare parts do not have waterproof function, and should be protected from being wet by water.
If the power cord has been damaged (exposed or broken wires), do not use it again to avoid electric shock.
Avoid strong collisions and vibrations, which may cause damage to the optical path of the instrument. It is recommended to use the original packaging of the instrument during handling.
When using the instrument for colorimetry, do not spill the colorimetric solution into the instrument's cell to prevent corrosion damage to the optical path system.
It is forbidden for the instrument to work in the space of corrosive gases to avoid damage to the circuit system.
When using cuvettes and cuvettes, it is necessary to wipe the water stains and residual solution on the outer wall of the tube, otherwise the measurement results will be biased.
Do not plug or unplug the power cord of the instrument when your hands are wet, and do not use a triangular socket with an ungrounded wire to prevent the possibility of electric shock.
Do not use the instrument in direct sunlight.
Do not put the limb in direct contact with the heated part of the digestion device, and be careful of burns.
When using the digestion and heating of the measured water sample, be sure to cover the protective cover provided in the instrument to ensure safe operation.
Do not disassemble the instrument for maintenance or change its internal structure without authorization to prevent accidents and failures.
When analyzing water samples, the reagents must be mixed and then digested after adding reagents to the water samples, otherwise the solution will be splashed during digestion.
During the use of the instrument, if there is a hardware abnormality or software operation failure, you should contact the technical department of the manufacturer, and do not repair and disassemble the instrument without authorization.
The solid reagents included in the instrument should be stored in dry, sealed, protected from light, and at low temperatures.
When water or other liquids accidentally get into the instrument, turn off the instrument immediately and unplug the power plug from the outlet.
If the digester is splashed or the cuvette breaks, turn off the power immediately and remove the power plug from the outlet.
After the instrument is used, the waste liquid used for colorimetry should be stored and disposed of centrally, and it is forbidden to put it aside or dump it at will.
If the colorimetric solution sticks to ** or clothing during use, wash it immediately with plenty of water. so as not to cause harm to **.
