Tools needed for calibration at your workbench
(1) Refer to the diagram above to properly connect the cables / harnesses.
Make sure the power of PS15-006 / host machine is OFF when connecting the harness to the
WBA. Failure to do so may cause electric shock and/or permanent damage to the equipment.

1. Description - calibration
Calibration sets a starting reference point for all the optical and magnetic sensors within the unit.
This task can be done at the host unit or at your workbench.
WHEN TO CALIBRATE
- After the acceptor component has been disassembled for repair
- After a sensor board has been replaced
- Whenever bill acceptance is degraded
- Once a year
You will need the following tools for calibration at your workbench.
PC: IBM PC AT or compatible
OS: MS-DOS V5.x or 6.x
The WBA calibration program supports MS-DOS only. This program can be also executed by
double-clicking the file, but use this method at your own risk. The execution may not be successful
depending on your machine configurations.

3) Change the current drive to the drive in which you have inserted the floppy disk (if it is A drive, enter A:).
4) To start calibration of WBA-12/13, enter “ADJ10” and press ENTER.
To start calibration of WBA-22/23/24/25, enter “ADJ20” and press ENTER.
B) Start by double-clicking the calibration program (Use at own risk)
1) Turn on the PC and start Windows 98/2000/Me/XP.
2) Insert the floppy disk containing the calibration program to the PC’s floppy drive.
3) Double-click the file to start the program (“ADJ10” for WBA-12/13, “ADJ20” for WBA-22/23/24/25).
5. Calibration procedure
(1) When the calibration program starts, screen 1 appears. Check the software name, type, and version
number. To end the software without making calibration, press ESC.
