12. Error and Display Lamp
(1) During measurement (including when the power is turned on)
●
error sign: The red light is on and "LLL" is displayed.
<
situation
>
No or an insufficient amount of sample is on the prism surface.
solution: Use with a sufficient amount of sample with a Brix of 0.0 to 33.0%.
<
situation
>
A sufficient amount of sample with a Brix of -2.0 to 33.5% is on the prism surface.
solution: 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.
<
situation
>
A sample with a Brix over 33.5% is on the prism surface.
solution: Use with a sufficient amount of sample with a Brix of 0.0 to 33.0%.
<
situation
>
A sufficient amount of sample with a Brix of -2.0 to 33.5% is on the prism surface.
solution: 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.
(2) During zero-setting
●
error sign: The red light flashes and "AAA" is displayed.
<
situation
>
When pressing the ZERO key, there is no water or an insufficient amount of water,
or a substance other than water on the prism surface.
solution:
Try zero-setting again with an ample amount of tap water.
<
situation
>
When pressing the ZERO key, with an ample amount of tap water on the prism
surface.
solution:
Turn the power (DC24V) off and ensure that the prism is clean. Try zero-setting
again with an ample amount of tap water.
(3) During measurement or zero-setting
●
error sign: Both red and green lights are on and arrow mark "
←
" is displayed.
<
situation
>
The
sample temperature is 9.4˚C or less, or 50.6˚C.
solution: The measurement values displayed are not properly temperature-compensated.
Measure the sample which temperature is 10˚C to 50˚C or more.
