ATAGO PAL-91S User manual

Measurement Value
The main scale indicates the concentration of Ethylene glycol and the secondary scale indicates the freezing temperature of
Ethylene glycol.
Freezing point changes depending on the concentration of the Ethylene glycol in the solution.
Automatic Temperature Compensation
The readings are corrected, based on the temperature of the prism, within the automatic temperature compensation range.
【Caution】
◇ easurements may fluctuate with hot or cold samples. Wait for approximately 20 seconds to press the START button.
easurements will stabilize once the instrument acclimates to the sample temperature.

Sample stage
Apply water and
samples on the glass
prism located in the
center of the sample
stage.

di erent than the actual product purchased.
LCD
easurement results,
prism temperature,

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.
3.
Measurement : not 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 : 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
correctly.
Proceed to measurement.
Wipe the prism clean with
tissue paper.
Measurement
【Caution】
◇ Do not use metal tools to apply samples on the prism as they may scratch the prism.
◇ Initial 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.
◇ The measured value is displayed even when the prism temperature falls below the temperature compensation range. It may be
displayed about 2% lower than the actual value.
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.
