Method of using subtraction mode
1. Set the load meter to the subtraction mode.
For details, see "Setting subtraction mode (6-9)".
Let us take the target load as 12.0t.
2. Fill the bucket with the first load, tilt the bucket back fully,
raise the lift arm above the horizontal position, then load the
dump truck.
Let us take the load as 5.1t.
The display shows the bucket load as 5.1t, and the total load
display shows 6.9.
When 15 seconds has passed since the start of the mea-
surement, the bucket load display goes out and returns to
0.0t. The total load display shows 6.9.
REMARK
When the bucket is tilted back fully and the lift arm is raised
above the travel posture, the measurement of the load starts. If
the first load is not discharged in Step 1, and the lift arm is low-
ered to the travel posture, then raised again to the horizontal
position, the load will be measured as the second load, even
though is has not been discharged. In this case, the bucket load
display will show 5.1t, and the total load display will show 1.8. To
cancel the mistaken second load data, press the load meter can-
cel switch. The measurement is cancelled and the total load dis-
play returns to 6.9.
