Error Messages “Pocket” Pocket” Cutting oil Refractometer 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 instrument is faulty. (Replace the batteries. Contact ATAGO if this error persists.) The sample measured outside the measurement range. 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.) PALPAL-102S Cat.No.4502 LCD Sample stage Measurement results, prism temperature, and remaining battery charge are displayed. The displayed value is an example. Apply water and samples on the glass prism located in the center of the sample stage.

ZeroZero-setting and Measurement Measurement Value Zero Zeroro-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. 1.

This unit converts refractive index into TDS (total dissolved solids) for convenient concentration measurements of cutting oil. The relationship between the concentration of cutting oil and its refractive index differs with each type of oil. Therefore, to determine the concentration of each type of oil, each solution should have its own custom conversion table to compensate for the value displayed by instrument. Conversion method (in the case of water based solutions) <How to calculate the Conversion Factor> Factor> E.g.) For an oil solution, with a concentration of 5% (dilution ratio at 20 times), mix 95ml of water to 5ml of undiluted solution. For this example, assume the displayed value, on the instrument, is 4.0. Next, convert the displayed value using the following relationship to determine the conversion factor; Actual concentration÷Displayed value, Ex: (5.0÷4.0 = 1.25 ). Once the conversion factor in known (1.25 in this example), measuring a sample with an unknown concentration is simple. Taking an unknown sample, assume that the measured value is 3.0. Using the simple formula, displayed value × conversion factor (3.0×1.25) the actual concentration of the sampled measured is 3.75. <Offset feature use> use> Program a conversion factor to automatically display adjusted measurement In the example above, the measurement values multiplied by the factor of 1.25 will be displayed.

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.

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.

To manually turn it off, hold down the START button for more than 2 seconds. <For oily/fatty samples> samples> Try stirring the sample on the prism while measuring to improve the repeatability of oily/fatty samples. 1. Insert a coin in the groove on the battery compartment cover. Turn the coin counterclockwise to remove the cover. Cleaning Cleaning Wipe off the sample, rinse with water, and wipe off the water to clean the sample stage thoroughly. Dry the sample stage completely with dry tissues. For oily samples: Clean oily residues with ethyl alcohol or mild soap, and then, rinse with water. Mild soap Ethyl alcohol 2. Insert batteries, observing the correct polarity. Figure１ 3.
