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

【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 30℃. 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.

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.)

【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.
Lubricate the O-ring regularly (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.
