Introduction

The instruments in the CEL-320/360 Series consist of the instrument unit shown,

plus CEL-6681 Dosimeter Microphone and Cable, or CEL-425 Microphone Adaptor.

Display

Preparation

Connect a 9 V battery (6LF22) to the terminals in the battery compartment in the

rear of the instrument.

DO NOT disconnect the battery once runs have been stored;

they will be lost.

With the instrument switched OFF, insert the cable connector of the Dosimeter

Microphone or the Microphone Adaptor into the socket in the top end of the case with

the red dot facing the front of the dosimeter.

Operation of the instrument is achieved by a simple sequence of key strokes.

Field Accuracy Check

Use a CEL-282 (Class 2) or CEL-284/2 (Class 1) Calibrator to perform a field

accuracy check (acoustic calibration) each time the instrument is switched ON and

again at the end of measurement.

Fit the CEL-4725 Coupler (supplied with the calibrator) into the calibrator cavity,

making sure it is firmly in contact with the shoulder in the cavity.

Fit the microphone into the coupler cavity, again making sure it makes contact

with the shoulder in the in the cavity.

Switch the calibrator ON and proceed as follows.

Dose data will be saved in the next

available data store.

2. Start Run

(Store Data)

When the run timer of a CEL-360 is

ON with beginning and End Times set,

the instrument waits counting back

the time remaining until the run starts.

When the run timer of a CEL-360 is

ON with Sync on, the instrument

waits until the clock is synchronised

with any selected profile time before

the run starts.

With a CEL-320 or when the run timer

of a CEL-360 is OFF, the instrument

waits for the next whole clock second,

then starts the run.

3. Then

The REC icon indicates that the

instrument is now storing data in the

first available store.

4. Inspect

the

Current Run

The display shows where data from

the current run is being saved (store
