Troubleshooting

The table below lists the symptoms, possible causes and recommended
solutions for common problems encountered with the P-T

RAK

®

particle

counter.

Symptom

Possible Cause

Corrective Action

Unable to
obtain zero
count (using
HEPA zero
filter)

Optics are flooded with
alcohol (caused by
multiple or prolonged
tilting of instrument).

Inlet screen assembly is
loose (not screwed tightly
together).

Inlet screen assembly is
missing internal
screen/washer.

Inlet screen assembly has
missing or damaged
O-ring.

Attempting to perform
zero with telescoping
probe attached.

Alcohol cartridge is loose.

Bad HEPA filter
(uncommon).

Internal leak inside
instrument (very
uncommon).

Let instrument run overnight
(using AC adapter) with storage
cap installed in P-T

RAK

®

particle

counter (

not

alcohol wick). This

will dry out the optics and
should restore proper operation.

Tighten assembly together
(hand-tight only).

Install screen. Securely tighten.

Make sure O-ring is in place on
inlet screen assembly tube.

Remove telescoping probe and
sample tube. Attach HEPA zero
filter directly to inlet screen
assembly.

Tightly install the alcohol
cartridge into instrument.

Try using a different filter. Or try
using two filters inline.

Must be diagnosed and
serviced at factory.
