Instructions specific to hazardous area
installations
(reference European ATEX Directive
94/9/EC, Annex II, 1.0.6.)
The following instructions apply to equipment covered by certificate
number Sira 05ATEX2027X for the CEL-320/IS and CEL-360/IS:
1
The equipment may be used with flammable gases and vapours
with apparatus Groups IIA, IIB and IIC and with temperature
classes T1, T2, T3 and T4.
2
The equipment is only certified for use in ambient temperatures in
the range -20oC to +40oC and should not be used outside this
range.
3
The certificate marking is detailed on drawing numbers
13-1920001A/IS-03 and 13-1920002A/IS-03.
4
Repair of this equipment shall be carried out by the manufacturer
or in accordance with the applicable code of practice.
5
The certification of this equipment relies on the following
materials used in its construction: Polybutylene terephlhalate
(PBT) and Polycarbonate (PC)
If the equipment is likely to come into contact with aggressive
substances, then it is the responsibility of the user to take
suitable precautions that prevent it from being adversely
affected, thus ensuring that the type of protection is not
compromised.
Aggressive substances e.g. solvents that may affect polymeric
materials
Suitable precautions e.g. regular checks as part of routine
inspections or establishing from the material's data sheet that it
is resistant to specific chemicals.
6
The certificate number has an 'X' suffix that indicates that the
following special condition of certification applies;
Under certain extreme circumstances, the non-metallic parts
incorporated in the enclosure of this equipment may generate an
ignition-capable level of electrostatic charge. Therefore, when it
is used for applications that specifically require group II, category
1 equipment, the equipment shall not be installed in a location
where the external conditions are conducive to the build-up of
electrostatic charge on such surfaces. Additionally, the
equipment shall only be cleaned with a damp cloth.

Data integrity is further protected by a dose microphone lead which is designed to resist knocks and abrasions without affecting the signal passing from microphone to instrument. Both instruments can be operated and deliver dose and SLM results without the need for other equipment, beyond an acoustic calibrator. -

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. - Page 8 Fit the CEL-4726 Coupler Calibrator supplied with the calibrator (CEL-110/1 or 110/2 ) into the calibrator cavity, making sure it is firmly in contact with the shoulder in the cavity. (To aid removal, the coupler flange does not fit close 'O' Ring against the calibrator housing).

Technical Information Specification Dosimeter/Sound Exposure Meter Standards: IEC 61252: BS EN 61252, ANSI S1.25 - 1992 for dosimeters and sound exposure meters. Electromagnetic and electrostatic compatibility: The sound level at which this personal sound exposure meter conforms to clause 15 of this standard is 85 dB. The personal sound exposure meter was tested in Dose mode using 85 dB due to the duration of testing. - Page 17 There is no degradation in performance or loss of functionality following the application of electrostatic discharges. The approved configuration for reference orientation as viewed by the operator is with the instrument in a horizontal position facing the noise source where the receiver of the electromagnetic field replaces the noise source.
