Handling of battery
◇Make sure to use a specified battery or that
supplied with the refractometer as an accessory.
When loading the refractometer with a battery,
pay heed to the polarities of the battery.
If a battery out of the specification is used, it
may cause smoke or fire because some batteries
are different in the voltage and polarities.
◇Be sure to always use alkaline batteries.
◇Don't heat, shortcircuit, burn a battery or
take it apart. If done so, it may cause burst
or fire.
◇When keeping or disposing a battery, protect
both poles with insulating tape, etc.
If a battery is kept or disposed as the poles are
not covered, it may cause shortcircuit, burst or
fire.
