2.1 MTX/MTB
The MTX and MTB Series scales have the same configuration and setup procedures.
NOTE: Configuration settings must be set before calibrating the MTX/MTB series scales.
2.1.1 Configuration
To Access The Configuration Settings:
1. Turn off the scale.
2. Press and hold the
ZERO
and
COUNT
keys.
3. Press and release the
ON/OFF
key.
NOTE : For the MTB, press and hold the ON/OFF key for at least 2 seconds.
4. Release the
ZERO
and
COUNT
keys.
To Enter Data:
1. The table above shows the parameter settings for the MTX/MTB series models. Use the
ZERO
(+) and
TARE
(–) keys to select the corresponding settings for each parameter (Cn–C8).
2. Use the COUNT key to enter the data and advance to the next step.
To Review:
1. After the operator enters C8 (see table above), the input displays C4–C1 setting.
2. If the C4–C1 settings are not correct, turn the scale off, then on again and re-enter the settings.
If the C4–C1 settings are correct, press the
COUNT
key.
3. The unit displays the C8-C5 settings.
4. If the C8–C5 settings are not correct, turn the scale off, then on again and re-enter the settings.
If the C8–C5 settings are correct, press the
COUNT
key.

2.7 QBX Series
Follow the steps below to set up and calibrate the QBX Series scale.
NOTES:
• Press any 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 1/2 capacity. However, when possible, calibrate using a full capacity
weight. See the table below for the unit system capacities.
• 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
tolerance (1%) is exceeded.
Setup Action
1Press and hold the MODE key until [Func] –> [CAL] appear in sequence, then release the key.
2Press and hold the T key, press the MODE key, then release both keys at the same time.
3 [un it] appears. Press the T key to increase the value of the right digit in this order:
[1] –> [2] –>. . . . [5]
Select the desired until system number (see table below).
4Press the MODE key to call up [on 0]. The QB automatically performs zero adjustment.
(Do not leave any weight on the pan).
5 After the QBX performs zero adjustment, [on FS] is shown. Place the calibration weight on the center of the
weigh pan (see table below for designated calibration weights).
6 When calibration is complete, the scale automatically returns to weighing mode.

The following pages describe the setup and calibration procedures for these products.

16 Ishida Setup & Calibration Manual
3.1 QB Series
Follow the steps in the table below to set up and calibrate the QB Series scale.
NOTES:
• Press the Pkey 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 1/2 capacity. However, when possible, calibrate using a full capacity
weight. See the table below for the unit system capacities.
• 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
tolerance (1%) is exceeded.
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.
