WN700D,WN700S Spectrophotometer
1、Storage
●Upon long time no use , cut off external power and remove the battery to avoid damage to the instrument resulting from battery fluid overflow.
●Store in a cool, dry environment with a temperature of -20 ° C ~ 50 ° C and a relative humidity of 85% or less.
2、Application
●Keep the standard whiteboard clean and avoid contamination of the standard whiteboard with stains, dust, etc.
●When using the instrument, the ambient temperature is 0 ° C ~ 40 ° C, the relative humidity is 85%, no condensation
●Avoid using the instrument in an environment with strong magnetic fields, severe vibration, dust, and smoke to prevent abnormal instrument data and performance failure.
●Avoid foreign matter such as liquid, powder, solid, etc. entering the inside of the instrument to prevent abnormal measurement data.
