3. OPERATION
A. SWITCH ON the CEL-62X INSTRUMENT (Refer to Figure 3)
Press the ON/OFF Key to switch the instrument on (see Figure 1). The instrument
software screens have been designed with colour coded top and bottom bars to enable
the user to know at a glance which part of the firmware (operating system) is currently
being accessed.
Colour coding is as follows:
RED – Stop screens. These screens are displayed when the instrument has completed
initialisation after power-up, as well as prior to taking a measurement run.
BLUE – Setting screens. These screens are used to set up the instrument correctly and
includes settings such as date and time, language and backlight.
LIGHT BLUE – Memory Results screens. This is where the results from measurement
runs are viewed.
GREEN – Run screens. These screens show a measurement run is in progress.
Measured values are stored in the Memory Results.
YELLOW – Calibration screen. This screen is automatically displayed upon application
of a 1kHz Acoustic Calibrator. This is where the instrument is calibrated prior to a run.
This is a precision instrument and should be calibrated before use to ensure
accurate measurements.
Also care should be taken that the operator does not unduly affect the sound field.
Ideally the instrument should be mounted on a sturdy tripod with the microphone
perpendicular to the source of the sound to be measured – the operator should be as far
behind the instrument as possible. If the instrument is to be hand held, then the arm of
the operator should be stretched out as far as possible to minimise reflections from the
operator’s body. Refer to Appendix B for the affects of the instrument on the sound field.
CEL- 62XA – When the instrument is powered up, the initialisation screens will be
displayed first, followed by the Graph screen in the Stop mode (Red Bars). Press Menu
(A) to access the Menu screen.
CEL- 62XB or CEL-62XC – When the instrument is powered up, the initialisation
screens will be displayed first, followed by the Octave (or 1/3 Octave on C models)
screen in the Stop mode (red bars). Press
View (B) to see the Graph screen. Press
Menu (A) to access the Menu screen.
The instrument is ready to make measurement immediately after the initialisation
screens have been displayed (approximately 10 seconds after switch ON).
