5. Press the SENS key on the front panel to return to the measurement
screen.
6. Use the LEVEL RANGE keys to set the level range to "100" if the
NC-74 is used, or to "120" if the NC-72 is used.
7. When a 1/2-inch condenser microphone is used for calibration, mount
the 1/2-inch adapter to the pistonphone NC-72 or sound calibrator
NC-74.
For 1-inch condenser microphones, the adapter is not required.
Note
For 1/4-inch microphones, the pistonphone NC-72
comes with a 1/4-inch adapter. There is no 1/4-inch
adapter for the NC-74.
8. Insert the microphone very carefully and slowly all the way into
the coupler.
9. Set the power switch of the sound calibrator or the pistonphone to ON.
