Test and Monitoring Functions
Apart from a brief initial start test (”eprom test”, ”ram test”, ”flash test”),
which is performed on every cold start of the OP3, a hardware test with test
functions for all the important components of the device can be initiated by
operator input.
Hardware test displays are in English, irrespective of the language set.
The hardware test is not initiated by means of the screen level but on turning
on the supply voltage. Press the following three arrow keys simultaneously
You can choose the following tests from the hardware test menu:
• CPU TEST,
• RAM TEST,
• EPROM TEST,
• FLASH TEST,
• V.24 (RS232) TEST,
• KEYBOARD TEST,
• DISPLAY TEST and
• TEST_ALL.
Choose the test you require with arrow keys ↓ and ↑; start the test by pres-
sing ENTER. The >> and << symbols show the menu item you selected in the
left and right borders of the display.
While an initiated test is in progress, an ”active” message is displayed. If an
initiated test terminates without errors, an ”ok” message appears on the
display for about two seconds.
You terminate a hardware test by choosing ”END OF TEST” from the menu.
