Functions Turns the power “ON” and “OFF”. <Control panel> Adjusts a moisture value bias. Selects a sample number. Averages measured values. Enters a minus correction value. -
Page 9: Before Measuring
6. Before Measuring (1) The unit is powered by six 1.5 V batteries (AA, alkaline). Remove the rear battery cover, place the batteries into the compartment taking care to correctly orient the positive "+" and negative "–" terminals. Then attach the battery cover. is displayed when the batteries become low. Replace all six with new batteries. -
Page 10: Directions
7. Directions 7-1. Measurement (1) Press the key to turn on the power. All elements of the LCD will be displayed for about 3 seconds. Subsequently, "calibration curve name," and "%" will be displayed. * At this time, if the display shows something other than the above, this unit may be in the abnormal state. Refer to “9. Warnings and Errors" on page 20. - Page 11 (3) Insert the bar sensor into raw cashew. * When the bar sensor is inserted, push the sensor firmly into the sample to place more than half of the sensor in the sample. If insertion is not deep enough, contact between the bar sensor and the sample is not sufficient and an accurate measurement result may not be obtained. * Do not stir, twist, or wrench the sample with use of the bar sensor in a reckless manner. Failure to observe this may apply excessive load to the bar sensor and accordingly cause damage to it. In addition, the state of contact with a sample significantly changes, which may greatly affect a measurement result.

Page 13: Average Display
7-2. Average display Pressing the key when the number of measurements is from 2 to 9 displays "measurement number" and "average value". At this time, “measurement number” and “average value” remain displayed, but if a measurement is continuously made, “measurement number” will be 1. * If the number of measurements exceeds 9, the measured value up to that point resets and measurement starts from measurement number 1. -
Page 14: Continuous Measurement Mode Setting
7-3. Continuous measurement mode setting If the continuous measurement mode is selected, measurements can be made without pressing the key for each measurement. (1) Continuous measurement mode setting In the step "7-1. Measurement (4)" on page 11, pressing the key causes the decimal point to blink and display the moisture value and bar graph. -
Page 15: Moisture Content Value Correction
7-4. Moisture Content Value Correction The moisture value scale of this unit is created by statistically processing the relationship between a standard method and electric resistance. However, depending on various conditions, there are cases where the standard method and the moisture value do not agree. In such cases, a moisture value bias can be adjusted (–9.9 to 9.9%) by the following method. -
Page 16: Setting The Alarm
7-5. Setting the Alarm When the sample having moisture higher than the set moisture value are measured, a buzzer sounds to issue an alarm. (1) Press the key. The numbers to the right of “ALARM” will blink. (2) Enter the alarm value. Enter a 2-digit number. To enter “20%”, press the keys in succession. -
Page 17: Making A User Calibration Curve
8. Making a user calibration curve The moisture value can be corrected by the following <Comparision test> linear equation with the range of the calibration curve slope 0.1 to 1.9 and intercept -9.9 to +9.9. Overmore, the corrected calibration curve can be stored in cannel No.02 to 15 as a user calibration. * As an example, if t he measur ement values from t he channel No.01 have a relationship as shown in the right graph compared to the standard method, correction... - Page 18 Ex.) When 1.1 and 1.0 are entered into the correction coefficients A and B respectively of the user calibration curve No. 03 (1) Press the key to turn on the power. All elements of the LCD will be displayed for about 3 seconds. After that, "RCA" and "%" are displayed. (2) Press the key, and the unit will be the calibration curve input mode.
- Page 19 (4) Enter a number for the correction coefficient A (0.1 to 1.9). The default value is "1.0". In this case, "1.1" is entered for the correction coefficient A. Successively press keys in the order of → (5) Enter a number for the correction coefficient B (-9.9 to 9.9). The default value is "0.0". In this case, "1.0" is entered for the correction coefficient B. Successively press keys in the order of → (6) Af ter the entr y is completed, the unit is in the state where the registered calibration curve is selected. Pressing the key enables measurement.
