Calibration 6-5

System Inventory

Select the Inventory icon from the toolbar to generate a list of items that make up your scanning
system.

Select the items you wish to calibrate.

Calibration

Select the Calibration icon from the toolbar to initiate the automatic calibration process. The ScanCal
program will prompt you through the calibration. Be ready to supply the corresponding passwords
when prompted by ScanCal.

ScanCal contains a feature that allows you to view the calibration steps without performing an
actual calibration. This is accomplished by using the Skip this Step button to skip a procedural
step(s). When using this feature the existing calibration settings will not change.

Calibration Without ScanCal

Password

To perform calibration, the calibration mode must be enabled. The Enter Calibration Mode (

) command

enables calibration, where

keyword

is the five-digit keyword (or password) currently configured for the

unit. Your scanning unit is shipped with a default password of

12345

. This password can be modified by

the Change Calibration Keyword (

) command, once Calibration Mode has been entered. Calibration

mode is ended by executing the End Calibration Mode (

) command.

Attempts to execute calibration commands without entry into calibration mode will result in a
calibration status error.

If the password is lost or forgotten, a new password can be entered after enabling the calibration mode.
This mode is enabled by indenting the Calibration Enable/Disable Pushbutton. After pushing in the button,
execute the

command to change the existing password. For more information, refer to the

Hardware

Protected RAM

section on page 6-2.

Disable writing to RAM after successfully changing the password by setting the Calibration
Enable/Disable Pushbutton to the disable (non-indent) position.

Note to ChartScan users: Early production ChartScan units do not have a Calibration Enable/Disable
Pushbutton. For these units the calibration mode is enabled by positioning the DIP switch right-most micro-
switch (#9) to the “1” (up) position. Note that ChartScan units with the pushbutton have it located on the rear
panel, as indicated in the NetScan figure (page 6-2).

Mode Indicator

To denote whether or not calibration mode has been activated, bit 7 in the Calibration Status Register will
be set after a valid

command has been executed. This bit is cleared by the

command (see “

E Command

”

in Appendix A).

You can verify the register status by the

command. A response of

U128

indicates that the unit is in the

calibration mode.

U2,

in the command reference section (Appendix A) contains details regarding this

command.

Command Active Indicators

Since the calibration commands require a few seconds to complete, bit 6 in the Calibration Status
Register will be set and the trigger LED will flash to indicate that a calibration command is active.
When these indicators are off, a subsequent calibration step can be started.
