Page 14: How To Make Bias Adjustment
6-5. How to make Bias Adjustment The calibration (scale) for this unit was prepared by determining the relationship between the moisture of copra resulting from a drying method and the electrical resistance of the copra, and then statistically processing these results. However, depending on various conditions, there are cases where the standard measurement method and the moisture value do not agree. -
Page 15: Setting The Alarm
6-6. Setting the Alarm An upper limit moisture alarm can be set. When copra is measured having moisture higher than the set moisture value, the alarm sounds with a beeping tone. 1. Press the key. The numbers to the right of “ALARM” will blink. 2. -

Page 17: Error Display
7. Error Display When there is a problem with the unit or with the measurement conditions, the following errors will be displayed for 4 seconds, and then the power will turn off. 1. There is a problem with the temperature sensor. Servicing is required. - Page 18 3. The measurement cannot be made because the temperature of the unit is below –5°C. Bring the temperature of the unit up to the operating temperature range (0 to 40°C), and make the measurement again. 4. The measurement cannot be made because the temperature of the unit is above 50°C.
