ATAGO PAL-BX/RI User manual

Main scale : Brix Secondary scale : Refractive Index
Brix represents the weight of sucrose in 100 grams of sucrose
solution as percentage by weight. When other dissolved solids
are present in the solution, Brix conversion may be applied.
Brix is a me
asure of the total dissolved solids in a solution and
indicates the combined concentration of all soluble substances,
such as sugar, salt, protein, and acids.
The displayed Refractive ndex value is not compensated for
temperature. The measured value is t
he Refractive ndex at the
displayed measurement temperature. Changes in temperature
directly affect the Refractive ndex of any sample (even for the
same sample at the same concentration level).
Automatic Temperature Compensation
The readings are corrected, based on the temperature of the prism, within the automatic temperature compensation range.
【Caution】
◇ Measurements may fluctuate with hot or cold samples. Wait for approximately 20 seconds to press the START button.
Measurements will stabilize once the instrument acclimates to the sample temperature.
Storage and Maintenance
Store the instrument in a dry place away from
direct sunlight. Exposure to humidity and heat
may damage the instrument.
Clean and dry the sample stage thoroughly,
following the “Cleaning” instructions.
Store the unit away from direct sunlight at a
stable temperature with
as little fluctuation as
possible.
Repair and Warranty
The instrument is warranted for one year from the date of purchase. This warranty is void if the instrument shows evidence of the
following. Send the included batteries as well if they are still in use.
• Having been disassembled by unauthorized personnel
• Damages to the prism and/or sample stage
• Water damage or having been dropped

Zero-setting and Measurement
Zero-setting
【Caution】
◇ Zero-set the instrument at the beginning of each day before use as well as after replacing the batteries.
◇ Let water on the prism acclimate to the temperature of the instrument before zero-setting.
◇ When “AAA” is displayed, wipe the prism clean, apply water, and press the ZERO button again.

Measurement : not Brix 0.0%
Press the ZERO
button while the
water is on the
prism.
4.
Zero-setting is
complete when “000”
blinks
twice and then stops.
Measurement : Brix 0.0%
1.
Wipe the prism clean and
apply about 0.3mL of tap water.
2.
Press the START
button, and after “---”
appears, the
measurement and the
prism temperature are
displayed.
The instrument is zero-set

tissue paper.
Measurement
【Caution】
◇ Do not use metal tools to apply samples on the prism as they may scratch the prism.
◇ nitial measurements may fluctuate with hot or cold samples. Wait for the instrument to acclimate to the sample temperature,
approximately 20 seconds, to press the START button. Alternatively, press the START button multiple times until
measurements become stable.
◇ Do not splash water above 50℃. The plastic may warp, which may compromise the water resistance.
•When measuring hot samples, place only the necessary amount and do not let it overflow from the sample stage well.
•When hot water is necessary to clean off hardened samples, use water-soaked gauze around the prism area and keep hot
water away from the body case.
◇ The displayed temperature is that of the prism and may not necessarily match the temperature of the sample.
1.
Wipe the prism clean and
apply about 0.3mL of the sample.
2.
Press the START
button
3.
After “---” appears, the measurement
and the prism temperature are displayed.
LCD Auto Shut-off>
The instrument will turn itself off after 2 minutes of inactivity. To manually turn it off, hold down the START
button for more than 2 seconds.
For oily/fatty samples>
Try stirring the sample on the prism while measuring to improve the repeatability of oily/fatty samples.
Cleaning
【Caution】
◇ Do not scratch the prism.
◇ The instrument is water-resistant, not waterproof, and should not be submerged.
1. Wipe off the sample.
2. Clean the prism and sample stage using a mild soap and thoroughly rinse with water.
3. Dry the area with tissues thoroughly.
Error Messages
The following messages alert the user when an operation has failed.
The battery is low. The prism temperature is below the temperature
range.
The ZERO button was pressed with nothing or
something other than water on the prism.
The prism temperature is above the temperature
range.
The START button was pressed with nothing or an
insufficient amount of sample on the prism.
The sample measured outside the measurement
range.
The instrument is faulty.
(Replace the batteries. Contact ATAGO if this
error persists.)
Too much light is entering the prism, and the
instrument cannot measure accurately.
(Shade the sample stage with your hand and take a
measurement again.)
Replacing the Batteries
【Caution】
◇
Fasten the battery compartment cover tightly to prevent water ingress or poor connection, which will
cause erroneous measurements. Push the cover in firmly and turn.
◇ When the O-ring on the cover is dirty or damaged, the water resistance may be compromised.
(Figure 1)
◇ When the battery icon indicates the low power level (
), replace both batteries with a brand new
set of AAA alkaline batteries (1.5V).
◇ Static images may occasionally appear on LCD. Such retained pixel charges do not indicate a faulty
display, consume the battery power, or affect the instrument’s performance in any way.
◇ Check the expiration dates on batteries before purchase.
◇ Zero-set the instrument after the batteries are replaced.
