Casella CEL CEL-360S - Manual (Page 7)

Once data saved by a CEL-360 instrument has been downloaded
to a PC, the user can specify a period over which to re-calculate the
projected % dose values. The software can also calculate six
exceedance time percentiles with levels preset to values specified by
measurement standards, plus one user specified time percentile.
5. Preparation for Use
5.1 Install Battery & Microphone
Connect a new 6LF22 or equivalent 9 V
battery to the terminals in the battery
compartment in the rear of the instrument.
DO NOT disconnect the battery
once runs have been stored as they
will be lost !
With the instrument switched
OFF, insert the lead connector of the
CEL-6681 Dosimeter Microphone or the
connector on the
CEL-425 SLM Adaptor
stalk into the socket
on the top end of the
case with the red dot
facing the front of the
dosimeter.
Remove the
connector ONLY by
pulling on the knurled
sleeve.
5.2 Perform Acoustic Calibration
Operations are controlled by a sequence of key strokes.
Perform a field accuracy check each time the instrument is
switched ON using a CEL-110/2 (Class 2) or CEL-110/1 (Class 1)
Calibrator as follows. It is also recommended that another acoustic
calibration be performed immediately after completing a measurement
run.
The calibration levels from both before and after are stored with
the run. When the second calibration occurs much later, provided the
same microphone assembly is used, the second level is attached to any
stored run that has no second calibration.
