Calibration Status
Once the TempScan/1100 or MultiScan/1200 hardware write protection is disabled, you can enter
Calibration Mode via the Enter Calibration Mode (
K
) command. When a valid password has been
executed and Calibration Mode has been activated, Bit 7 in the Calibration Status Register (
CSR
) will be
set. This bit is cleared by the End Calibration Mode (
E
) command.
During Calibration Mode, the TempScan/1100 or MultiScan/1200 unit will be in one of two states: Idle or
command active. Whenever a calibration command is active, Bit 6 in the Calibration Status Register (
CSR
)
will be set and the TRIGGER LED indicator will flash for a few seconds. Once all of the indicators are off,
the unit will return to an idle state, and Bit 6 in the
CSR
will be cleared and ready for the next calibration
command. At this point, the next step in the procedure can be started. For more information on
Calibration Mode, see commands Enter Calibration Mode (
K
) and End Calibration Mode (
E
) in the
chapter API Command Reference. For more information on the Calibration Status Register (
CSR
), see
chapter System Operation.
Calibration Password
Note: Attempts to execute calibration commands without entry into Calibration Mode will
result in a calibration error, as follows: The Invalid Command Bit (Bit 0) in the
Calibration Status Register (
CSR
) will be set, and in turn, any set Bits 0 to 5 in the
CSR
will be mapped into the Calibration Error Bit (Bit 3) in the Error Source Register
(
ESC
).
To Change the Calibration Password
1. Disable calibration protection by setting the rear panel DIP microswitch 9 to the up (1) position. Then
enable Calibration Mode via the Enter Calibration Mode (
K
) command with a valid password. The
keyword
is the five-digit keyword (or password) currently configured for the unit. Your scanning unit
is shipped with a default password of
12345
. If the calibration password has not been changed, enter
K12345
.
2. Once Calibration Mode has been entered, this password can be modified. Enter the Change
Calibration Keyword (
*K
) command with a new five-digit password.
3. Wait for command to complete. The TRIGGER LED indicator will flash for a few seconds.
4. Monitor the Calibration Status Register (
CSR
) via the User Status (
U
) command
U2
to ensure that the
command completed without error.
5. Disable Calibration Mode with the End Calibration Mode (
E
) command. Re-enable calibration
protection by resetting DIP microswitch 9 to the down (0) position.
For details on any of the above commands, see Appendix A, API Command Reference.
