UM 2410 & UM 2510 ELECTRONIC SCALE
BASIC OPERATION
To ensure that the maximum error is within the
scale manufacturer's accuracy of +/- 1%, the
Seed Runner must be stationary and on level
ground when using the scale.
1. Turn scale "On" and let it warm-up at least 15
minutes.
2. Zero balance scale by pushing and holding
the "Zero" button. This should be done where
Seed Runner is going to be unloaded (on level
ground if possible).
3. Load Seed Runner and let scale total up
weight. When Seed Runner is full, drive up
to planter wagon or truck and stop. After scale
settles on a number, push the "Tare" button.
Scale indicator will show zero.
4. Start unloading Seed Runner. When planter
wagon or truck is full or Seed Runner is empty,
the negative amount shown on scale is actual
product in planter wagon or truck.
5. Push the "Net/Gross" button. This will put the
scale back into the gross weighing mode again.
If the Seed Runner has grain in it yet, it will tell
you how much weight is left on the Seed Run-
ner. You can now load the Seed Runner again
and repeat the same unloading process.
6. It is recommended to periodically fully-empty
the Seed Runner and rebalance the scale.
