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.
1.
Wipe the prism clean and
apply about 0.3mL of the sample.
2.
Press the START
button.
3.
After displaying
“
---
”
,
“

”
flashes until measurements
stabilize.
To stop continuous measurement.
Press the START
button.
Continuous
measurement is
finished and the
readings are retained.
The instrument will turn
itself off after approx. 2
minutes of inactivity.
※To manually turn it off,
hold down the START
button for more than 2
seconds.
4.
After measurement and the
prism temperature are
displayed, measurement is
repeated continuously
thereafter.
The instrument will turn itself
off after approx.2 minutes of
continuous measurement.
<Tip for stable measurement>
This model features the Mode-S technology for increased repeatability. For best results measuring hot or cold
samples, stop the measurement once measurements start to stabilize, and then press the START button again.
<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.

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.

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.
