Refer toSpecifications on page 5.The particle counter is thoroughly inspected and tested at the factory and is ready for useupon receipt. When received, inspect the shipping carton for damage. If the carton isdamaged, notify the carrier and save the carton for carrier inspection. Inspect the counterfor broken parts, scratches, dents, or other damage.Particle counters use a laser-diode or Helium Neon gas laser light source and collectionoptics for particle detection. Particles scatter light from the laser diode. The collectionoptics focus the light onto a photo diode that converts the bursts of light into electricalpulses. The pulse height is proportional to the particle size. Pulses are counted and theiramplitude is measured for particle sizing. Results are shown as particle counts in thespecified size range (differential count mode) or as total particle counts (cumulative countmode). A microprocessor controls all instrument functions. Count data is shown ascumulative counts or differential counts.2.4 How to use the touchscreen interface2.5 AccessoriesAccessoryPortAll Version 2 Software,Demo VersionStylusPower cord (120V and 240V)The MET ONE 3411 is operated by use of a TFT color touchscreen located on the frontpanel of the unit (Figure 3 on page 13).

ConfigurationFigure 17 Beep setting5.3 Area managementLocations, Areas and GroupsThe sampling positions (or LOCATIONS) can be organized within larger spaces (orAREAS). This arrangement is a function of the geographical placement of the samplingposition within a facility. Data from each sampling position is associated with a uniquenumerical designation assigned automatically by the instrument (range of 001 to 999)plus the common name for that point assigned by the user, such as LAF Bench 32 orDiffusion Oven Loader. It is permissible to have duplicate LOCATION names withinseparate AREAS. For example, LAF Bench #2 could be a designation for Cleanroom422 and also Cleanroom 423 as long as the combination of AREA/LOCATION name isunique.In addition, each sample point or LOCATION can be associated with a GROUP that hascommon attributes as defined by the user. Examples might be All ISO Class 7 positionsin Building 4 or All Locations Sampled Once a Month. It is permissible for aLOCATION to belong to one or more GROUPS. It is also possible to have LOCATIONSthat have no GROUP association at all.These combinations of LOCATIONS as AREAS or GROUPS allow for quickerdevelopment of sampling strategies relating to alarm levels, sampling methodologyand/or frequency.Once a library of LOCATIONS, AREAS and GROUPS is developed for a facility, thisinformation can be rapidly transferred to other instruments by copying the configuration ofthe Master instrument to a USB memory stick and then transferring that configuration tothe remaining particle counters. Refer to Copy a configuration to USB drive (memorystick) on page 30.An area defines a specific place within a facility, such as a clean room, that is identifiedfor sample testing.When area configuration is complete, continue to push RETURN to navigate back to theCounter Navigation screen (Figure 18)32

The raw count alarm willbe triggered whenever one or more of the limits set for the active size channels havebeen reached during a count cycle. The concentration alarm limits can be used toestablish alarm limits based on a calculated volume such as a cubic foot or a cubic meter,even if the total volume of air sampled during a count cycle does not equal the specifiedvolume.As an example, to set the 0.5 µm alarm limits for an ISO Class 5 area based on acalculated volume, the concentration mode would be set to counts per cubic meter andthe alarm limit set to 3520. During the ensuing count cycle(s) the instrument will assessthe potential alarm condition based on the volume of air sampled up to that moment andthe volume of air for which the limit is set. The alarm will be triggered whenever thecalculated value (based on actual counts, the actual sampled volume, and the target totalvolume) reaches the value set by the user in the concentration alarm column.5.6 Password protection and user management5.6.1 Enable user logonThe password function allows a system administrator to prevent users from modifying thecounter settings.

The solution may penetrate the display or the electronicsand damage the instrument.• Cap the sample air intake nozzle before cleaning.• To clean the exterior of the unit, spray a mild cleaning solution on a soft cloth and wipethe unit.• To clean the touchscreen, first wipe it with a soft cloth. If debris remains, wipe with asoft cloth moistened with a mild cleaning solution or alcohol.After high counts, especially unexpectedly high particle counts, perform a zero count teston the instrument to ensure counts are registering accurately and to clear the counter ofany residual particles.To purge the unit:1. Place the zero count filter on the intake tube of the particle counter (item 11 inFigure 1 on page 11).2. Turn the unit on and logon, then navigate to the Sample screen and push theRUN icon.3. Repeat this process until the counts decrease to zero.9.3 Update the instrument softwareNotice: Do not complete the following procedure without receiving upgrade files andexplicit direction from Hach Company.1. Download a self-extracting.ZIP software update file from Hach Company.2. Extract the files to a compatible USB flash drive. Do not move or delete any files.Note: The use of factory-furnished USB drives is recommended (refer to Parts and accessorieson page 83).3. Remove the batteries and AC power from the particle counter.4. Plug the USB flash drive into the USB port.5. Apply AC power to the particle counter.6. Upon successful completion of the update process, the instrument resumes the bootprocess.75
