BLZZRD ™ Portable Refrigerated Sampler
Section 9 Maintenance
9-7
Memory Tests –
Test the unit’s memory. If either screen shows
you a message saying that the memory failed the test, contact
Teledyne ISCO’s Technical Service.
Display Test –
Displays a test pattern on the screen. If the
pattern does appear correctly, the display or its circuitry require
repair. Some indications of a faulty display during this test would
be pixels always on or off, or unreadable characters.
Pump Test –
Runs a test of the pumping system. If selected, the
controller first runs the pump forward for a short period. Next, it
displays an ON/OFF ratio number. After displaying the forward
pumping ratio, the sampler reverses the pump to obtain a purge
ratio. The acceptable range is between 0.80 and 1.25. If either
ratio is outside the acceptable range, the pump requires repair.
You do not need to pump liquid while running the test, and you
can run the test with or without a tube in the pump.
Self-diagnostics, continued…
If you select YES, the controller tests the forward
and reverse pumping operation.
The ratio should fall within the 0.80 to 1.25 range.
Values outside this range indicate a pump problem;
contact Teledyne ISCO Technical Service.
8. Select YES to test the distributor, NO to skip this
test.
If you select YES, the controller tests the distributor
operation.
Note: the controller must be mounted on
the sampler assembly with a distributor arm
attached.
After finding the arm flexure, the arm is positioned
over 24 bottle positions.
9. The final screen of the diagnostics routine asks if
you want to reinitialize the sampler controller.
Select YES only if you want to restore all programs
to the default settings and to clear all memory
partitions. Select NO to retain the programs and
data and to exit the diagnostics.
