  • Page 30: Selecting The Mode (Measuring Mode)

    8-3-2 Selecting the MODE (Measuring mode) The ‘MODE’ (measuring mode) setting is used to specify the conditions under which measuring is to be completed. As shown in the table in subsection “8.1 Types of Settings”, the mode may be set to automatic operation mode, timed operation mode, or any one of five other modes.
  • Page 31 2) Specifying settings for TIME (Standard drying & Timed ending) mode In this mode, the measuring time is specified beforehand. When the specified measuring time is reached, measuring is ended. Measuring time may be specified in 1-minute increments anywhere in a range from 1 to 240 minutes or measuring may be specified to be performed over a continuous period of 12 hours.
  • Page 32 3) Specifying settings for RAPID (High-speed drying) mode High-speed drying mode is useful for measuring samples with high levels of moisture content. In high-speed drying mode, the sample is dried at 180°C until the change M in moisture content over a 30- second period becomes lower than setting, then drying will be continued at the specified drying temperature.

  • Page 38 Note: Read Section 12 before use of this part. 7) Specifying settings for PREDICT (Predictive measuring) mode Predictive measuring mode is used to predict the change in moisture content and calculate the predicted final measurement before drying has been completed. Thus measuring time can be saved. Note that some materials have properties which make it difficult to obtain accurate predictions.

  • Page 39: Temp (Drying Temperature) Setting

    8-3-3 TEMP (Drying temperature) Setting The following describes the procedure to specify the drying temperature in conducting measurements. While the default drying temperature is 120°C, depending on the type of sample, its moisture content, or other conditions the proper drying temperature may vary. To find the proper drying temperatures for different types of materials, conduct repeated measurements until you find the correct temperature to use for each material.

  • Page 40: Bias Setting

    (standard) values as moisture measurements are the result of various conditions. The bias may be set to adjust the measured value by the MOC-120H to the expected (standard) value. Thus,the measured value using the MOC-120H can be treated to be equivalent to the existing (standard) measuring methed.

  • Page 52: Precaution On Conducting Measurements

    11. Precaution on Conducting Measurements Precaution on conducting multiple measurements in succession Placing a sample on the sample pan which is already warm may cause moisture from the sample to evaporate before measuring is begun and causes errors in measurement result. Always be sure to use a cool sample pan when performing a subsequent measurement.

  • Page 53: Predictive Measurements

    However, because moisture balance operates by heating samples to evaporate the moisture content, it takes a fair amount of time to obtain results. MOC-120H has a feature that not only reduces measuring times but also brings the method to adjust partial drying measurement results to those obtained with a standard method of measuring.
  • Page 54 Preparatory measuring mode In preparatory measuring mode, predicted measurements are displayed while measuring is in progress and measuring is halted under the same conditions as when operating in automatic operation mode. The difference between the measured values of automatic operation mode and pedictive measuring mode is displayed as the necessary bias.

  • Page 55: Procedure For Obtaining Predicted Measurements

    12-2 Procedure for Obtaining Predicted Measurements 1) Use preparatory measuring mode to obtain the appropriate bias value for the predictive mea- surement. (See “12-2-1 Calculating the bias to be specified when operating in predictive measure- ment mode” for instructions.) 2) Use the bias obtained in preparatory measuring mode in step 1) to perform the measurement, and evaluate the predicted measurement.
