5.4.5 Check display
This diagnostic step is used to check all light emitting diodes and the
display for functionality.
• Prepare instrument for diagnostic test (see section 5.4.2).
• If need be, press <9> key repeatedly until
diagnosis
>diag/display test
• <ENTER>
After the <ENTER> key has been pressed, the program automatically runs through a
test sequence for a visual check on the light emitting diodes and the display.
⇒ The light emitting diodes for OVERLOAD, THERMOSTAT, ZERO and
PROG R/S are switched on for a certain time.
⇒ Power on test pattern (each pixel active) appears.
⇒ Both lines of the display are cleared.
⇒ Both lines of the display are written to with the characters “#”, “H”
and finally with “I”.
⇒ Both lines are written to from right to left with the continuous moving
display „0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ“.
⇒ The light emitting diodes for OVERLOAD, THERMOSTAT, ZERO and
PROG R/S flash in succession for a brief time.
• The test sequence can be held by pressing any key (with the excep-
tion of <9>) and restarted.
• The test is quit with the <9> key.
