Press
to turn Off the flow. The measured flow should be within
±5% of the displayed Current Flow. If this is not the case, perform the
Flow Rate Calibration procedure.
8.
To resume sampling, install or replace the sampling cassette with
sampling filter installed. Reinstall the PM
10
inlet on the sample tube.
9.
Press
to restart the Sampler and continue the current sampling
program.
Use the following procedure to perform an internal leak check. This test
will require a blocked test cassette p/n 36-012078.
1.
Install the filter cassette carrier containing the filter cassette with
blocked test cassette installed into the Sampler and push on the handle
to move the filter cassette carrier into the sampling position.
2.
Press
to return to the Audit and Calibration menu.
3.
Scroll to Leak Checks, press
, with the cursor at Internal, press
.
The following message displays:
MAKE SURE THAT A LEAK CHECK DISK IS IN THE SAMPLE
FILTER LOCATION!!
Press
to begin testing.
4.
A Pass or Fail message will display at the end of the leak check cycle. A
pressure drop of 140 mmHg or less is the Sampler’s leak check pass
criteria. Record the reading on the vacuum gauge. This reading should
not drop by more than 140 mmHg during this 60 second period. This
corresponds to a leak of 80 mL/min. If this reading does drop by more
than 140 mmHg during this 60 second period, trace the internal flow
paths to identify problems in tubing or connections.
5.
If a Fail message is displayed, remove the filter cassette carrier and
check the seals and repeat the leak check test. If the system fails the leak
check a second time, the leak is before the test cassette. Isolate the the
leak and repair.
