Step 3 To setup the calibration process, press therkey
to move into the Calibration Menu.
Step 4 To set the calibration level, press the
d and
u keys to highlight “Cal Level”,
NOTE: The output level specified by the
calibrator manufacturer will be at
standard temperature and pressure. In
practice the level is a function of
temperature and static (barometric)
pressure, so a corrected level should be
used. Similarly, the sensitivity of the
microphone itself is a function of
temperature and static pressure. For
directions on compensating for
temperature and static pressure during
calibration, see "Correction of
Calibrator Output Level" on page 2-17.
Step 5 To set the value of the sound level provided by the
calibrator, press the
rkey. This displays the Cal
Level window.
Step 6 Then use the
landrkeys (to move the cursor
position) and the
uanddkeys (to change dig-
its) to enter the proper level.
Step 7 To select the new calibration level press the
c
Check key.
