How to understandthe threshold:
1.Each wavelength hasits threshold.
2.If the current value > Max. Value, the alarm ofcorresponding
wavelength will be FAIL .
3.If the current value < Max. Value, but > Warning Value, the
alarm of corresponding wavelengthwill be PASS .
4.If the current value < Warning Value,but > Min.Value, the
alarm of corresponding wavelengthwill be WRNG .
5.If the current value < Min. Value, the alarm ofcorresponding
wavelength will be FAIL .

Battery charge
First you mustuse the rechargeablebatteries. When the energy
is less than20%, you shouldcharge the batteries.Long time low
energy,the life ofthe batteries willbe short. When charging, the
battery indication on LCDwill flash. After charging fully, the
indication will stopflashing and showfull. Don't chargefor more
than 24 hours.If charging whileusing the device,the time willbe
longer.The rechargeable batteriesmust be indevice when youuse
the AC/DC adaptorfor charging. Anddo not chargethe
non-rechargeable batteries, orthe device willbe destroyed andalso
lose the guarantee.
