post-sampling analysis, although there is no guarantee that the sampled spots have not been contaminated. Used filter
tape should never be “flipped over” or re-used! This will result in measurement problems. Loading a roll of filter tape is a
simple matter using the following steps:
1.
Turn the APDA-371 on and enter the TAPE menu (Note: This is not the same as the TEST > TAPE menu). If
the nozzle is not in the UP position, press the TENSION soft-key to raise the nozzle.
2.
Lift the rubber pinch roller assembly and latch it in the UP position. Unscrew and remove the clear plastic spool
covers.
3.
An empty core tube MUST be installed on the left (take-up) reel hub. This provides a surface for the used tape
to spool-up on. HORIBA supplies a plastic core tube to use with the first roll of tape. After that, you can use the empty
core tube left over from your last roll to spool-up the new roll. Never fasten the filter tape to the aluminum hub.
4.
Load the new roll of filter tape onto the right (supply) reel, and route the tape through the transport assembly as
shown in the drawing. Attach the loose end of the filter tape to the empty core tube with cellophane tape or equivalent.
5.
Rotate the tape roll by hand to remove excess slack, then install the clear plastic spool covers. The covers will
clamp the rolls to the hubs to prevent slipping.
6.
Align the filter tape so that it is centered on all of the rollers. Newer units have score marks on the rollers to aide
in visually centering the tape.
7.
Unlatch and lower the pinch roller assembly onto the tape. The APDA will not function if the pinch rollers
are latched up, and it has no way of automatically lowering the roller assembly!
8.
Press the TENSION soft-key in the TAPE menu. The APDA-371 will set the tape to the correct tension and alert
you if there was an error with the process. Exit the menu.

Self-Test
The APDA-371 has a built-in self-test function which automatically tests most of the tape control and flow systems of
the unit. The self-test should be run right after each time the filter tape is changed, and it can also be used if the
