10. Press the "A" ("WAKE UP") button on the top panel of the PDM unit
to ensure that the display screen appears.
11. If the display screen does not appear, open the case and double-check
the battery connections. Reassemble the case, and press the "A"
("WAKE UP") button again. If the display screen does not appear,
contact Thermo Fisher Scientific.
12. Properly dispose of the used PDM battery packs. Recycling is the
preferred method of disposal. Contact Thermo Fisher Scientific for
further information. Do not dispose of the battery packs in fire or heat.
CAUTION Always properly dispose of the PDM battery packs (recycling is
preferable, contact Thermo Fisher Scientific for further information). Do
not dispose of the battery packs in fire or heat. ▲
13. Perform a sample line leak check and a case leak check.
If it becomes difficult to install the mass transducer, lubricate the two O-
rings located inside the top of the mass transducer section. Because this
procedure is easier to complete with the front panel removed, check the
O-rings
mass transducer O-rings while replacing the battery pack assemblies (or as
necessary). Tool/materials needed for this procedure:
Phillips screwdriver
●
Cotton swab
●
Silicone compound.
●
WARNING Whenever the PDM case is opened for maintenance, you must
perform a case leak check after reassembling the case. ▲
1. Remove the PDM cover plate (refer to the instructions earlier in this
chapter for information on opening the case).
2. Locate the mass transducer chamber of the PDM and the two O-rings
in the top of the chamber
(Figure 5–45
and
Figure
