TROUBLESHOOTING
6-1 TROUBLESHOOTING LEAKS
Liberally cover all fittings, seals, and other pos-
sible sources of leakage with a suitable leak test
liquid such as SNOOP (part 837801). Bubbling
or foaming indicates leakage. Checking for bub-
bles will locate most leaks but could miss some,
as some areas are inaccessible to the applica-
tion of SNOOP. For positive assurance that
system is leak free, perform one of the tests
above.
NOTE:
Refer to Specification in Preface for maxi-
mum pressure limitations.
For differential measurement, the leak check
must be performed for the measurement and
reference side separately.
For analyzers with parallel gas paths, the
leak check must be performed for each gas
path separately.
6-2 POCKET PC CONNECTION FAILURE
In the event the connection between the Pocket
PC and the MicroCEM fails, a connection failure
dialog will be displayed. It will display the fol-
lowing message:
Connection with uCEM lost, retrying…
A Cancel button will be displayed. The Micro-
CEM software will continue to attempt to recon-
nect with the MicroCEM indefinitely and will stop
when a connection is made or the cancel button
is pressed.
If the Cancel button is pressed, any setting
changes that were made without pressing OK to
accept will be lost. If Auto Calibration was in
process, it will be completed by the MicroCEM
even though the connection was lost.
6-3 TROUBLE LED
The Trouble LED output is activated whenever
there is a critical alarm that has not been ac-
knowledged. This provides both an output from
the MicroCEM box and an LED indication.
