QB Series Operation Manual

 

2.0

Weighing Operations

 

The following section describes weighing operations of the QB Series balance, including: units of measure,
general weighing, weighing with a tare, batching, comparator, and piece counting.

 

2.1

Units of Measure

 

Table 2-1 shows the various units of measure (maximum capacity and minimum increment) available on your
QB Series balance. 

 

NOTE: There is no push-button conversion from one unit to another. The QB Series balance is capable of showing only
one unit of measure during a weighing operation. Switching to another unit of measure requires a change in the set up
procedure (see Section 2.2)

 

.

 

Table 2-1. Unit Capacities

 

2.2

Changing Units of Measure

 

After the balance has been powered up (see Section 1.7 on page 5), all display segments momentarily illuminate,
followed by two flashes of all displays. The device then displays default weighing mode. If the balance does not
show a 

 

0.00

 

 value after the normal start sequence, press and release the 

 

T

 

 key. The balance returns to a 

 

0.00

 

value. The default unit of measure from the factory is 

 

g

 

 (grams). If the balance has already been used, a different

unit of measure may already be activated. To change the active unit of measure, use the following steps:

1. Ensure that there is nothing on the platform and that the weight reading is 

 

0.00

 

.

2. Press and hold the 

 

F

 

 key until the word 

 

Func

 

 is displayed.

3. Release the 

 

F

 

 key. The display changes to show either 

 

1.SET.1

 

 or 

 

1.SET.2

 

.

4. Repeatedly press and release the 

 

F

 

 key to change the display, until it reads 

 

7.un.1

 

 (if the active unit of

measure is currently 

 

g

 

). If the active unit of measure is another value, 

 

7.un.

 

 is displayed, followed by any

one of the following values: 

 

2, 3, 4, 5, 6, 7, 8, 9, A, b,

 

 or 

 

C

 

5. Refer to Table 2-1 above and Table 4-1 on page 15 to determine the setting required for the desired unit

of measure.

6. Repeatedly press and release the 

 

T

 

 key until the appropriate value is displayed.

7. Press and release the 

 

P

 

 key to confirm the setting.
