Caution Burn hazard Electric shock hazard ● Do not damage, heat, or place heavy object on the power cable or connectors. Otherwise, it may cause fire or electric shock, etc. ● When connecting with other devices, first, turn off the power of each unit. ● Do not connect/disconnect the power plug with wet hands. Otherwise, it may cause an electric shock, etc.

4. Description of operation keys Operation key Description [MENU] key Used for setting up and making a calibration curve. [ENTER] key Used to determine the currently selected item. [MEA.] key Used for measurement. [TABLE] key Used to set ON/OFF of the rotation table. [ZERO] key Used for zero-adjustment.
5. Preparing the main unit * Clean the measurement window. If it is not clean, measurement may not be performed correctly. * When closing/opening the light shielding cover, be careful not to pinch the fingers. ① Install the main unit. Install the unit in a place where direct sunlight is avoided and not be subjected to significant vibration. ② Attach the light shielding cover. Attach the light shielding cover by inserting the columns provided on the top surface of the unit into the mounting holes on the cover.
6. Specifying measuring conditions 6-1. Selecting the sample cell (container) According to the form of the measuring sample, select a sample cell from four types listed in the following. * Make sure that the selected one fully covers the measurement window. Also, use the same one in making calibration curve and actual measurement.
6-2. Deciding whether to use the light shielding cover The light shielding cover can avoid effects from external light. It is preferable to use the cover in order to avoid external light. * Perform measurement closing the light shield- * The cover may not be usable depending on the ing cover if possible.
6-4. Setting the sampling amount Put the sample in the sample cell selected in section 6-1 and determine the sampling amount. * If the sampling amount (sample height) is not consistent, it may affect the absorbance. * When not using the light shielding cover, determine the sampling amount under the same condition of ex- ternal light as measurement.
7. Making the calibration curve ● Necessity of calibration curve The infrared moisture analyzer measures the near-infrared absorption of the meas- uring object, and converts the obtained data to the moisture. Therefore, a conver- sion formula that calculates actual moisture from near-infrared absorption is re- quired.
7-3. Preparing the samples The sampling amount set in section 6-4 is represented as A . The sampling times set in section 7-2 is represented as B . At least the sampling amount of A x B per moisture is required. Prepare enough samples to be used in the measurement of standard moisture content (section 7-5) as well.
7-6. Optical measurement (entering the calibration data) ■ Set the main unit. ( ⇒ 5. Preparing the main unit (P.10)) ■ Perform measurement under the same condition in making calibration curve and regular measure- ment. Following the procedures below, enter the channel names and sample calibration data obtained in section 7-1 to 7-5.

9. Zero calibration ● What is zero-adjustment? If errors occur in the measurement results, read the absorbance obtained from reflection on the zero-adjustment plate. The measurement result will be stabilized by setting the absorbance as zero. Make sure to perform this operation when making calibration curve or in the regular measurement as well. Also, the zero-adjustment is required after the power is turned on.
