Turn the power (DC24V) off and ensure that the prism is clean. If the error persists
even when there is a sufficient amount of sample to cover the prism, air bubbles or
undissolved solids may be the cause.
●error sign: The red light is on and "HHH" is displayed.
A sample with a Brix over 33.5% is on the prism surface.
