Precautions of Operation and Storage
CAUTION
• Insertthebatteriesintheinstrumentbyreferringto“6.1BatteryReplacement.”
• ABlankcoverisprovidedontheupperpartofbackcasing.
 Don’tremovetheBlankcoverexceptwhentheUSBadapterorPrinteradapteris
connected.
• Donotusetheinstrumentnearnoise-emittingequipmentor
where there may be a sudden change of temperature. Otherwise, the instrument may
give an unstable reading or errors.
Removal of Dirt
Do not wipe the instrument using any solvent (chemicals) such as benzine or paint
thinner, as this may damage or discolor the front panel.
 Useadryclothtocleantheinstrument.
Storage Conditions
• Donot leavetheinstrument exposedtodirect sunlightor inahot andhumid location
such as the inside of a vehicle, for any prolonged
length of time.
• Iftheinstrumentwillnotbeusedforaprolongedperiod,removethebatteries.
