Sharp ER-A440 - Manual (Page 27)

3) Check items
Check printing of the termination message.
4) Test termination
This check is terminated automatically.
The test terminates with the test and message printed
In this SSP check, set the data for check in the empty area of SSP
entry REG and erase the data for check after completion of check.
Therefore SSP setting before check is not cleard.
If therefore there is no SSP entry REG remainedfor SSP check,
F-print is performed to terminate the program without check.
[9] Drawer open sensor test (For standard test)
1) Key operation
2) Functional description
State of the drawer open sensor is sensed and displayed.
3) Check items
X Description
O Drawer open sensor detected. (Drawer opend)
C Drawer open sensor not detected. (Drawer closed)
a) Check opening of the specified drawer.
b) Check the display indication when the drawer is open and closed.
4) Test termination
Press any key. The test terminates with the test and message printed
[10] Drawer open sensor test (For remote drawer)
1) Key operation
2) Functional description
State of the drawer open sensor is sensed and displayed.
3) Check items
X Description
O Drawer open sensor detected. (Drawer opend)
C Drawer open sensor not detected. (Drawer closed)
a) Check opening of the specified drawer.
b) Check the display indication when the drawer is open and closed.
4) Test termination

[11] Standard RAM test
1) Key operation
2) Functional description
Perform the following check for the standard RAM 128 KByte SRAM.
The memory contents should not be changed before and after the
check.
Perform the following processes for memory address to be checked
(1E0000H~1F0000H).
PASS1: Save memory data.
PASS2: Write data "0000H."
PASS3: Read and compare data "0000H," write data "5555H."
PASS4: Read and compare data "5555H," write data "AAAAH."
PASS5: Read and compare data "AAAAH."
PASS6: Restore the memory data.
If a compare error occurs in the check sequence PASS1-PASS6, an
error print is made. If no error occurs through all address, the check
ends normally.
The following address check is performed further.
Check point address = 1E0000H, 1E0001H
1E0002H, 1E0004H
1E0008H, 1E0010H
1E0020H, 1E0040H
1E0080H, 1E0100H
1E0200H, 1E0400H
1E0800H, 1E1000H
1E2000H, 1E4000H
1E8000H, 1F0000H
3) Check the following items:
Check the termination printout.
4) Test termination
The test terminates after printing the termination printout.
Termination printout:
Normal termination 120
Abnormal termination Ex – – – – – 120
X = 01: Data check error
02: Address check error
Note: When an error occurs, the error print is performed and the
check is terminated. The error occurrence address is shown in
hexadecimal at positions shown with
.
