MACHINE MONITOR WITH LOAD METER
REMARK
In the condition in Step 1 or Step 2, if the lift arm is lowered to
near the travel posture, then raised again to measure the
bucket load again, the load meter will think that work was car-
ried out for the second loading operation.
The bucket load display will show 5.1 ton
The remaining load display will show 1.8ton (= 6.9 - 5.1)
In this condition, press the load meter cancel switch to return to
Step 2.
3. This is the second load.
The load in the bucket is 4.9 tons.
6.9 - 4.9 = 2.0 tons, so the next target load is displayed as
2.0 tons.
4. This is the third load.
The result of measuring the load in the bucket is 5.0 tons.
This is 3.0 tons over the target amount, so -3.0 tons is dis-
played.
5. The target load is displayed as -3.0 tons, and after 3 sec-
onds, the display changes to the display shown on the
right.
The target value of 2.0 tons is the target load after complet-
ing the loading of the second bucket.
6. Load the target of 2.0 tons from the 5.0 tons loaded in the
bucket.
When this is done, "2.0" flashes for the target load.
7. After loading, lower the lift arm and then raise it again in
order to weigh the amount remaining in the bucket. The
amount remaining in the bucket is weighed and displayed.
