STORAGE

The instrument should be save up in a ventilated room where the ambient temperature is 5

-

45

, RH

90% and dew is not allowed. These conditions are needed to protect the 1iquid

crystal display, in addition, keep the instrument from smoke, gas, acid, alkaline and other
corrosive materials, be sure not to place the instrument in high temperature and more dust
place so as to keep the instrument clean. After delivery within 18 months, if the users abide
by the regulations of transportation, storage and operation regulation, and the quality is
below the specification, our company take responsible for free repair or rep1ace a new one.
