5.9 Span Mass Audit
The Mass Audit screen, located in the Test menu, is used to verify the performance of the E-BAM
beta attenuation system. A zero and span foil (included in the E-BAM accessory kit) will be required
to complete this procedure. When this screen is accessed, the nozzle will be raised, and the display
will provide instructions to enter the zero-calibration foil.
The filter tape
must be loaded
for this test! Insert the zero foil
above the filter tape
between the
nozzle and vane, as shown in Figure 5-10
Note that the membrane is keyed and can only be
inserted one way. Take care to minimize tape movement. When the zero foil is detected, the nozzle
will automatically lower
to the foil and the four-minute measurement will commence.
Figure 5-10 Starting the Zero Test
After four minutes, the nozzle will raise, and the screen will prompt to remove the zero foil. Remove
the zero foil, taking care to minimize tape movement.
Figure 5-11 Completing the Zero Test
Once removed, the display will change to list the current span foil setting as shown in Figure 5-11.
Compare this value to the value written on the span membrane tool. If the values do not match, tap
the green bordered span value field and enter the value listed on the span tool. Press the grey
CONTINUE button to continue to the next step.
