Numeric Display indicating that the weight of an empty container must be
registered.
4. Apply an empty container (or a load representing the weight of an empty
container) on the platform. Wait 5 seconds for the load to stabilize, then press
. 100% will flash in the Alternate Numeric Display indicating that the weight
of a full container must be registered.
5. Apply a full container (or a load representing the weight of a full container) on the
platform. Wait 5 seconds for the load to stabilize, then press . This
completes the training process, and the SET TANK indicator will turn off.
6. From this point forward, the Alternate Numeric Display will show the percent of
material remaining in the container from 0% to 100%.
NOTE: The 100% weight must be larger than the 0% weight by at least 200g. If not,
“Err” will show on the Alternate Numeric Display. To clear the error, retrain as above
using a 100% weight that is at least 200g larger than the 0% weight. During training,
the ZERO key may be used to assist in setting the 0% and 100% values. This will
have no effect on the training, as the Tank Capacity Mode relies on absolute, not
relative, weights.

Battery Level Indicator
The battery level indicator shows the relative strength of the batteries. Full power is
indicated by four bars. As the batteries are depleted, the number of bars displayed
decreases, until no bars are left. At this point, it is necessary to replace the batteries (refer
to the Battery Installation section above). If the battery power drops to the point where the
DRS220 can no longer function accurately, the alarm will beep 20 times and the power will
turn off automatically. When the batteries are replaced, and the scale is turned back on, the
DRS220 will resume operation with all previous setting intact.
