Abrupt loss of power
No response when
sampler is lowered
into operating position
Results not repeatable
(too scattered)
“ Block Probe Failure ”
If you lose power to your instrument, we
recommend that you check that your outlet
is providing the correct amount of power.
Check that your cord is firmly plugged into
both the instrument and the outlet. Visually
inspect the fuses, and change as necessary.
If there is no response when you lower the
operating cradle into operating position,
there could be a problem with the internal
switch that initiates the test. Try turning the
instrument on and then off. If the problem
persists, please consult an Advanced
Instruments Model 3300 Service Manual or
contact Advanced Instruments for Hot-Line
Service.
Most often, poor repeatability comes as a
result of poor technique or not following
procedure. Be sure all sample tips are clean,
as well as the sampler itself. If the sampler
plunger wire has not been changed in 500
tests, change it as described in Chapter 4. If
the sampler is not properly calibrated, re-
calibrate it using the procedure described in
Chapter 4.
