CAUTION
◇ The refractometer needs the "zero setting" (calibration) before it is used for the first
time in a day. Moreover, if the ambient temperature changes during the daily work with
the refractometer, it needs the zero setting again.
◇ The zero setting is also needed whenever the battery is replaced.
◇ Do not use any metallic implement for dropping water on the prism because the metal
tool possibly damages the prism surface.
