Operation Instructions
Turning 476 On and Off
The 476-moisture monitor can be turned on and off using the ON / OFF button located on the bottom left hand
side of monitor. When the unit is first turned on all the lights on the display will be lit up for a short time before
it goes into operating mode.
Selecting Crop Type
The 476 moisture monitor allows you to choose the crop that is being harvested.
To switch crop types:
1. With the monitor turned on, press the SELECT button to change between crop types ALFALFA and
CORN on the right side of the monitor. Use the ALFALFA selection for alfalfa, alfalfa grass mixtures,
gasses, oats and another small grain silage crops. Use the CORN selection for corn and sorghum
crops.
2. After pushing the crop selection keys a light next to the selection will come on within 1 second,
indicating that the box is re-set for that crop.
3. Once crop type is selected, monitor is ready to take reading for that crop. NOTE: The Load Average
and the Field Average is reset when crop type is changed.
Checking Load Average
The load average is the average of all moisture readings that have accumulated since the last time the load
average had been checked. NOTE: The load average will automatically reset after each time the AVERAGE
button is pushed.
To display the load average:
1. Press and release the AVERAGE button.
2. LA will display then the percent moisture will display. Example 68.
3. The percent moisture will be followed by (--) meaning that the load average has been reset.
Checking and Resetting Field Average
The field average is the average of all moisture readings that have accumulated since the last time the field
average was checked.
To display the field average:
1. Press and hold the AVERAGE button for longer than 3 seconds.
2. Keep holding the AVERAGE button. FA will display.
3. After FA is displayed, keep holding AVERAGE button then field average will display. Example 64.
4. At this time, you can release the AVERAGE button to allow the monitor to keep accumulating the field
average.
5. To reset the field average press and hold both the AVERAGE and SELECT buttons.
Remote Average Switch
The gray pigtail wire that comes out of the wiring harness, allow you to connect a switch (not provided) that can
be used for remotely signaling/checking the Load Averages. A more convenient location such as, the armrest
console or a floor-operated switch, may make it easier to check averages more frequently. The switch should
be a momentary on switch.
To do this:
1. Connect the gray wire to one side of the switch and a 12-volt power to the other side of switch.
2. Press or trigger the switch using the same procedures as used for checking and resetting load average.
It doesn’t work for field average.
