Balances 15
3.1 QB Series
Follow the steps in the table below to set up and calibrate the QB Series scale.
Step Action
1Press and hold the F key until [Func] –> [CAL] appear in sequence, then release the key.
2Press and hold the T key, then press the F key, then release both keys.
3 [un it] appears. Press the T key to increase the value of the right digit in the following order:
[0] –> [1] –> [2] –> . . . .[9] –> [A] –> [6] –> [d] (repeat from 0).
Select the desired unit system number (see table below).
4Press the F key to call up [on 0]. The QB automatically performs a zero adjustment. (Do not leave any weight on
the pan).
5 After the QB performs zero adjustment, [on FS] automatically appears. Gently place the designated calibration
weight on the center weigh pan (see table below for designated calibration weights).
6 When calibration is complete, the scale automatically returns to the weighing mode.
NOTES:
• Press the P key to cancel calibration procedures and return to the weigh display.
• If
[o–Err] appears on the display, the weight exceeds the scale capacity.
• Standard calibration weight is

• If
[1–Err] appears on the display, the calibration weight is less than 50% of the standard.
• If
[2–Err] appears on the display, an object other than the calibration weight is on the pan, or the display

3.2 MB Series
NOTE: MB Series scales cannot be calibrated. They are stamped or sealed by local weights/measurement offices. When
calibration is necessary for the MB, contact your local dealer.
Follow the steps in the table below to set up and calibrate the MB-E Series scale.
Step Action
1Press and hold the F key until [Func] –> [CAL] appear in sequence, then release the key.
2Press the ZERO key. While holding it down, press the F key, then release both keys.
The display blinks [on 0] to indicate zero adjustment is being performed. Verify that no load is on the weigh
platter.
3 After the MB-E performs zero adjustment, [on FS] automatically appears. Gently place the designated
calibration weight on the center weigh pan (see table below for designated calibration weights).
4 When calibration is complete, the scale automatically returns to the weighing mode.
NOTES:
• In Step 2, if the F key is pressed prior to the ZERO key, the scale will return to weighing mode.
• Standard calibration weight is

• If
[o-Err] appears on the display, the weight exceeds the scale capacity.
• If
[1-Err] appears on the display, the calibration weight is less than 50% of the standard.
• If
[2-Err] appears on the display, the display tolerance (0.4%) is exceeded, or the scale may be defective.

3.3 MB-RE Series
Follow the steps in the table below to set up and calibrate the MB-RE Series scale.
Step Action
1Press the S key and release. [SA CAL] appears in the display.
2 The display blinks [CAL. 0] which indicates zero adjustment is automatically performed.
3 Display changes to [CAL. on] which shows the mode advanced to span adjustment.
4Turn the calibration knob counterclockwise to CAL until it stops (see figure 4.1 below). Now the calibration
weight is loaded. Display starts flashing to indicate span adjustment is being automatically performed.
5 Display changes to [CAL oFF].
6 Return calibration knob at WEIGH point by turning it gently until it stops with a slight sound. Calibration weight
inside has been unloaded to display [End].
7 When span calibration is complete, [0] is shown on the display.
NOTES:
• Pressing any other key other than ON/OFF will interrupt the operation and show [StOP].
• Calibration knob should be turned gently, but don’t stop until fully turned. At [CAL] it stops lightly, at
[WEIGH], it stops with a sound.
•Keep calibration knob at
while it is at [CAL].
• The calibration will not advance after
windshield or a stable base.
• If
[3-Err] appears on the display after zero adjustment is performed, an object other than the calibration
weight is on the pan.
• If
[4-Err] appears on the display after returning the knob to [WEIGH], this indicates that the error at span
varies too much from that of the factory-set value.
