Hold the 83011 ND Filter so that the label is UP (filter element is on the right-hand side) and insert
it above the tape. Be certain it is fully inserted and seated squarely against the pins at the front of
the measurement module. See Figure 7-8.
CAUTION: Be very careful not to move the tape as this will affect the measurement!

The measurement module will close and the display will show the completion time remaining (see
Figure 7-6) for the span filter portion of the test. At the end of the test, the measurement module
will open and the results will be displayed as shown in Figure 7-7.
Note: Figure 7-7 and Figure 7-8 display results with the optional C-12 BRC 370 UV option.
Standard configuration CALIBRATE AUDIT results will only display BC results.
The values should be within ± 5% of the values indicated on the label of the 83011 ND Filter.
Record the results and then press the CONTINUE button.
The measurement module will open and the
display will indicate when it is safe to remove
the ND filter as shown in Figure 7-9.
Remove the filter and then press the EXIT
button to return to the CALIBRATE menu.

Should the values fail to be within ± 5%, the most likely reason is inadvertent tape movement
during the test. The test should be repeated, paying particular attention to maintaining the tape
stationary. If the test still fails, contact the Met One Instruments, Inc. service department for
assistance. See Section 1.2 for contact details.
