Weighing Operations

8. The display returns to a
0.00
value for the appropriate unit of measure.
To change to a different unit of measure, repeat steps 1 – 9 above.
2.3
General Weighing
The following section provides a step-by-step procedure on general weighing using the QB Series balance.
1. Power up the balance (see Section 1.7 on page 5).
2. All display segments momentarily illuminate, followed by two flashes of all displays. The device then
displays default weighing mode. To change the default unit of measure, please refer to Section 2.2 on
page 6. If the balance does not show a
0.00
value after the normal start sequence, press and release the
T
key. The device returns to a
0.00
value.
3. Gently place the item to be weighed on the platform. The unit of measure indicator begins to flash
indicating the balance is registering the weight of the commodity. The value display begins to update.
When the unit of measure indicator ceases flashing, the device is stable and you can read the weight
value.
2.4
Weighing with a Tare
The following section provides a step-by-step procedure on weighing with a tare using the QB Series balance.
NOTE: Whenever the tare function is activated, the effective weighing range of the device is reduced by the value of the
tare. For example, on a QB-600 with a total capacity of 600g, if a tare of 100g is entered into the balance, the total
effective NET weighing range of the device is only 500g (total rated capacity [600g] - tare value [100g] = 500g. Any
attempt to weigh over the effective weighing range results in a “o-Err” error message.
1. Power up the balance (see Section 1.7 on page 5).
2. The balance displays default weighing mode. If the balance does not show a
0.0
value after the normal
start sequence, press and release the
T
key.
3. The default unit of measure is displayed. To change the unit of measure, see Section 2.2.
4. Gently place the empty container on the platform. The unit of measure indicator begins to flash,
indicating that the balance is registering the weight of the commodity. The value display begins to
update. When the unit of measure indicator ceases flashing, the balance is stable and you can read the
weight value.
5. Press the
T
key. The zero display (
0.00
) appears.
NOTE: The value of the original tare must be
≥
+/- 4 displayed divisions from zero. If the original tare
value is
≤
+/- 3 divisions from zero, the device automatically re-establishes a new zero setting before the
T button can be activated. The tare function is not available. To disable this “auto-zero” feature, please
refer to Section 4.0 on page 15.
6. Gently place the product to be weighed in the previously tared container. The unit of measure indicator
begins to flash indicating that the balance is registering the weight of the commodity. The displayed
value begins to update. Continue adding commodity until the display indicates the desired weight value.
When the unit of measure indicator ceases flashing, the device is stable and you can read the weight
value.
NOTE: To view the gross weight of the commodity and the tare, remove the container with its contents
from the weighing platform. The total weight is displayed as a negative number. To return to normal
weighing, replace the container with its contents on the platform.
7. To weigh another commodity and tare or to re-use the current tare and weigh additional samples, remove
the commodity and container from the platform and press the
T
key to have the display return to a
0.00
reading, then repeat steps 1– 6.
2.5
Batching
The following section provides a step-by-step procedure on using the batching feature of the QB Series balance.
NOTE: Whenever the tare function is activated on a QB balance, the effective weighing range of the device is reduced by
the value of the tare. For example, on a QB-600 with a total capacity of 600g, if a tare of 100g is entered into the balance,
the total effective NET weighing range of the balance is only 500g (total rated capacity [600g] - tare value [100g] = 500g).
Any attempt to weigh over the effective weighing range results in a “o-Err” error message.
1. Power up the balance (see Section 1.7 on page 5).
