Provisional operating instructionsCEL-6760Outdoor Kit case for CEL-360 460 Logging DosimetersIntroductionThe CEL-6760 case is used to protect the CEL-360&460 Logging Noise Dosimeters when used for short to mediumtemm monitoring in exposed locations.The system is powered from a rechargeable battery that can provide up to 6 dayscontinuous operation.Larger capacity batteries may be used to extend this logging time if required.The loggingcapability of the CEL-360&460 enables a low cost environmental logger to be realized with regular data being savedto memory for later analysis using standard CEL-6704(dB12)Windows compatible software programs.The CEL-360 460 Dosimeter can be programmed from a PC using either CEL dB10 or dB12 Windows Analysissoftware.A measurement run can be selected which will store the overall results for the whole of the run.In additionshort time interval profiles can be set to enable the time history to be viewed when the data are downloaded to a PC.These profiles can be the time average level,Leq or the maximum or minimum level for intervals of under 1 minute.Forintervals of 1 minute or above the CEL-360 460 will save statistical parameters such as the LN10%,LN90%as wellas the Leq.Any valid combination of up to 10 parameters may be chosen in a CEL-360 to suit the particularmeasurement requirement (up to 2 in a CEL-460).List of standard partsThe description CEL-6760 Mini Environmental Case consists of the weatherproof case that houses the CEL-360 or 460Logging Dosimeter,the tube for the microphone and cable,the preamplifier assembly adaptor and the C6759 powersupply cable.The CEL-16038 rechargeable battery pack is also available which is rated at 12V 3.2 Amp hour (Ah)capacity and a CEL-4672 foam windshield.All of these items can be located in the custom designed foam inside thecase for easy transportation to and from site.A CEL-16029 charger unit and C6646 charging cable must be orderedseparately to recharge the CEL-16038 battery pack.The CEL-6760 Case is normally used with the standard CEL-360/K1 Logging Noise Dosimeter kit which includes the CEL-282 Acoustic Calibrator and the CEL-6704 (db12)software.The CEL-6704 (dB12)Graphical presentation software package allows for the display and recalculation ofdownloaded results at the end of a Run.AssemblyOpen the CEL-6760 Mini Environmental Case (MEC)using the special key provided and take out the microphone tube.Remove the front layer of foam and connect the spade tags of the C6759 power cable to the terminals of therechargeable battery pack (CEL-16038)taking care to observe the correct polarity.Pass the other end of the cablethrough the foam so that it becomes available for connection the flying lead in the dosimeter.Make sure that the CEL-360 or 460 Dosimeter is switched OFF.Remove the 9V battery (LR6,PP3)from the CEL-360 or 460 dosimeter andconnect the power lead from the internal rechargeable pack in the case.This should be done as quickly as possible toprevent the dosimeter from l
