2.11 Built In Tests (BITs)
(Box Controller Only)
When power is first applied to the ADFM box controller, an
internal self-test will automatically be performed. On the control
box, result messages will scroll on the LCD display, finishing
with a display showing the ADFM firmware version number on
the first line and a hexadecimal-coded event/error map on the
second line.
2.11.1 Testing Interval Routine execution of the built-in tests is not required during
normal system operation. Execution of selected built-in tests
from software is recommended quarterly or at each battery
change, whichever is more frequent. The built-in tests should
also be performed whenever a hardware problem with the ADFM
is suspected.
2.11.2 Test Record By default, the software will create a log containing details of all
ADFM operations, including the status of the error code map and
the results of all built-in tests. No further test record is required
unless specifically requested by Isco Service personnel.
2.11.3 Power-up BIT
Procedure/Sequence
Switch off the power to the ADFM.
After an interval of at least ten minutes, switch the power on
again. The ADFM’s LCD display should show the firmware
version and error code map followed by the wakeup message:
RD Instruments:

Flow Meter
The ADFM should begin displaying the results of the power-up
BIT. The power-up BITs will last approximately one to two
minutes, after which the LCD will show the firmware version on
the first line and BIT error and event code on the second line:
ADFM Ver. V6.xx

09000080
For code definitions, refer to Table 2-2 on the following page.
Note
If no events or errors occurred, the second line will show only
zeros (
00000000
).
To repeat the power-up BIT tests, turn and release the
spring-loaded Reset key switch located on the front panel.
