5. Install the keypad.

If the 20 s delay has elapsed before the cover and keypad have

been installed, CAL stops blinking and the instrument becomes

fully operational.

6. During the 20 s calibration delay, or when fully operational (with

no data being logged), press the + keys simultane-

ously to enter calibration mode, which is indicated by "C" ahead

of the displayed level.

The instrument displays SPL in dB(A) with Fast time weighting.

7. Switch the calibrator ON.

When used with the CEL-281 and CEL-6050 Coupler at standard

temperature and pressure, the calibrator generates a 1 kHz

signal at 114.0 dB, so the display should show "C 114.0 dBA".

8. If the display does not indicate 114.0 dBA, use the or

keys to obtain the correct level.

Acoustic calibration is now complete.
