screen. This allows the user to see if there is space for the next run, or

whether the contents of a store must first be cleared to make room as

described in Section 1.6. Then the user is offered the choice of recali-

brating (i.e performing a field accuracy check) or continuing with the ex-

isting calibration settings. If the battery level is too low for reliable

operation, a warning is displayed.

1.4 Field Accuracy Check (Acoustic Calibration)

Either: Press to use the existing calibration settings and proceed

directly to the SETUP menu (Section 1.5).

Or: Press to perform a field accuracy check (acoustic calibration).

Acoustic calibration of the CEL-268 will normally be performed with a

CEL-284/2 Acoustic Calibrator (IEC 942 Class 1L), while the CEL-368

will use a CEL-282 Acoustic Calibrator IEC 942 Class 2L).

With the CEL-268 and CEL-284/2, carefully fit the calibrator over the

end of the microphone, making sure the microphone is correctly seated

against the shoulder in the calibrator cavity.
