5. HARDWARE CHECK
This machine is provided with the function to watch for any abnormality in the hardware.
n
When an error occurs in the hardware (internal power voltage), the message of STATUS [XXXX] is displayed. 
The power lamp flashes in red. (It differs depending on the setting of “ STATUS ALERT” of the FUNCTION.)
n
When only a temperature error occurs, the message of “TEMPERATURE” is displayed on the loft lower section of the screen. 
The power lamps of red and green flash alternatively. (It differs depending on the setting of “TEMPERATURE ALERT” of the FUNCTION.)
n
The error position can be checked. There are following four methods. 
■ METHOD 1
1 ) SERVICE MENU 2 is displayed.
2 ) Select “HARDWARE CHECK” with [VOL+ ( 
2 )][VOL- ( 4 )] buttons,
and press [BRIGHT+ ( 
3 )] button. “HARDWARE CHECK” menu
is displayed.
3 ) The watch result and the current measurement value of the 
hardware are displayed.
The measurement value of the internal voltage displayed is the A/D
conversion value. 
The normal range is as shown below.
4 ) For the countermeasures against NG positions.

5 ) Press [MENU] button to return to the previous screen, and termi-
nate the operation.
■ METHOD 2
1 ) Send “HTST0000” that is 232C command.
2 ) Result is returned.
MEMO

“OK” or “NG” is displayed.
After turning ON the power, if an abnormality 
occurs to be “NG” once, the “NG” state is kept 
until the main power is turned OFF.
Measurement

■ METHOD 3
Check with the “STATUS[XXXX]” number.
1 ) When an error occurs, four-digit figures are displayed after the
message of “STATUS” on the left lower section of the screen. They
are assigned as follows.
■ METHOD 4
Check with the item of “STATUS” on the “Product information (INFOR-
MATION)” screen. 
When [DISPLAY] button is pressed, the “INFORMATION” screen is dis-
played. Check with the “STATUS” item on the screen. 
It takes some time necessary for judgment of a temperature abnormality
and a hardware abnormality as shown below:
n
Temperature abnormality: 
Min. 2 minutes (Exceeding the threshold value 3 times continuously
in the interval of 1 minute).
n
Hardware abnormality: 
Min. 18 seconds (Exceeding the threshold value 4 times continuously
in the interval of 6 seconds).
Though, therefore, the threshold value is exceeded on the “HARD-
WARE CHECK” screen of SERVICE MANU 2 or in the periodic send/
test mail, “OK” may be displayed.
In addition, when “NG” judgment is made once, “NG” state is main-
tained until the power is turned OFF/ON. Even if, therefore, the target
value is reduced below the threshold value, the judgment may be “NG”
with a normal value.
