1.
Moisture:
Press Moisture button to turn meter on. The BHT-1 displays con-
tinuous moisture readings when turned on. The unit should display 00.0 if
the bale chamber is empty. The BHT-1 reads moisture between 8% and
40%. Readings below 8% are displayed as 00.0. Readings above 40% are
displayed a 99.9.
NOTE: The BHT-1 takes several readings before displaying their aver-
age every two seconds.
2.
Backlighting:
When the unit is on, press the Light button to turn backlight-
ing of the display on or off. When the module is turned off and later turned
on, it will remember the backlighting mode of when it was last operating.
3.
Calibration Check and Reset:
When the unit is on, press the Check button
to recalibrate the moisture circuit to the current conditions of the sensor and
its environment. The BHT-1 will automatically adjust to dirty sensor contacts
and the relative humidity inside the chamber. We suggest that it be common
practice to recalibrate the meter every time the unit is turned on.
If the bale chamber is empty, the unit will display approximately 12.0 after
recalibration, signifying correct calibration.
If there is an obstruction, such as a bale, in the chamber or if the sensor
electrodes are very dirty, the unit will display 99.9. If the bale is removed,
and the meter still reads 99.9, the electrodes must be cleaned. (See Care
and Maintenance). If the meter must be used before the electrodes can be
cleaned, the unit will still operate using its last calibration points.
