Calibrating Temperature

Introduction

The moisture sensor contains a temperature sensor, which measures the
grain temperature for use in adjusting the measured grain moisture.

Calibrating
Temperature

Follow these procedures to calibrate temperature:

Step

Action

1

Press the MOIST key until the temperature reading “xx DEG F”
appears at the bottom-left of the display.

2

Use the bottom-left UP or DOWN ARROW keys to set the
temperature to the ambient air temperature, which automatically
changes “x T OFFSET”. (You can press the MOIST key to display
“x T OFFSET”).

Notes:

For accurate moisture readings, it is more important that you not change

the temperature offset while harvesting than it is to have it set exactly
right. Therefore, after you set it, leave it at that setting.

To calibrate temperature accurately, you must obtain an accurate

ambient air temperature after the temperature has been relatively stable
for several hours.

If the combine has sat overnight, the moisture sensor may be cooler than

ambient air temperature because the air can warm much more quickly
than the sheet metal of the combine. If you are adjusting temperature
without harvesting grain, it is best to do it when the combine has been
sitting in a constant ambient temperature for several hours.

If you set temperature while harvesting grain, the sensor measures grain

temperature, which will be close to ambient if the air temperature has
been constant for several hours.

To get the most accurate setting, check grain temperature at the combine

with a thermometer.
