CHAPTER 1Introduction andUnpackingThe AEROTRAK Model 9303 Handheld Airborne Particle Counter(particle counter) is a lightweight, handheld particle counter witha backlit LCD display. It operates on the included lithium-ionbattery or AC power.This model has a 0.1 CFM (2.83 L/min) flow rate and counts inuser-adjustable bin sizes of 0.3, 0.5/1.0/2.0/2.5, and 5 microns(center channel is selectable). Up to 1500 data sets can be storedand downloaded for analysis and reporting using the TRAKPROLite utility included with the device.Unpacking the AEROT RAK HandheldAirborne Particle CounterCarefully unpack the AEROTRAK Airborne Particle Counter fromthe shipping container and verify that all the items shown in thephotos below and listed in the following tables are present.Contact TSI immediately if items are missing or broken.Model 9303 AEROTRAK Airborne Particle Counter Parts ListQty.

CHAPTER 2Getting StartedThis chapter provides information to help you use the Model 9303including:• Installing the Isokinetic Inlet• Providing Power• Quick StartInstalling the Isokinetic InletThe Isokinetic inlet smoothly accelerates air into the inlet of theinstrument. To install, simply screw the probe directly onto thethreaded inlet nozzle.Installing an Isokinetic Inlet2-1

Providing PowerThe Model 9303 may be powered using its internal rechargeablelithium-ion battery or through an AC power cord.Notes:• When using AC power, the battery is charging when the redLED next to the power connector is on.• Removing/changing the lithium-ion battery or disconnectingAC power does not cause the loss of data.• You should fully charge the battery before use.!!WARNINGThe battery supplied by TSI (700019) has built in protection againstexplosion and fire hazard. Do not use a substitute.WARNINGDo not use non-rechargeable batteries in this instrument. Fire,explosions, or other hazards may result.Installing the Battery1. The battery is shipped separately and has to be installedbefore use.2. Remove the battery cover on the back side of the handle with asmall, flat-blade screwdriver3. Connect the battery to the socket as shown below.4. Insert the battery with the connector at the top and replacethe battery cover. Make sure all wires are inside and notpinched in the cover. Do not over-tighten the screw.5. Fully charge the battery before use.2-2 AEROTRAK Handheld Airborne Particle Counter

To Use AC Power1. Remove the AC transformer parts from their package andidentify the appropriate plug for your needs. Plugs areavailable for all common countries.2. Remove the insert from transformer using the slide lock andtilt the insert out.3. Tilt the appropriate plug into the transformer receptacle.4. Make sure it locks into place.Getting Started 2-3

5. Plug the DC end of the transformer cord into the counter.6. Plug the AC end of the transformer cord into an AC outlet.7. The Power LED lights when the battery is charging. When thePower LED is off, the battery is fully charged.8. When the battery is charged, unplug the power supply.Quick StartThe best way to quickly get started is to refer to the printed“Quick Start Guide” included with your instrument. It will helpyou to quickly set up the instrument and begin sampling. Refer tothe sections below for more detailed information on configuringand running the instrument.2-4 AEROTRAK Handheld Airborne Particle Counter

CHAPTER 3OperationThe Model 9303 is controlled using the integral keys and thebacklit display.IsokineticInletBacklitDisplayKey PadPowerLEDDCAdapterSocketUSB PortTo turn on the instrument, press the On/Off key.

The instrument turns off.Performing a Zero CheckA zero check should be performed periodically. It should also beperformed before conducting any important testing orcertification.3-2 AEROTRAK Handheld Airborne Particle Counter

To Perform a Zero Check1. Turn on the instrument and wait until the default screenappears.2. Unscrew the Isokinetic probe if attached. The zero checkcannot be performed when the isokinetic probe is attached tothe instrument.3. Attach the zero filter to the inlet nozzle located on the top ofthe instrument by screwing the assembly onto the inlet of theinstrument.4. Refer to the section Main Menu and Basic Operation below toconfigure the instrument.5. Press the Run key and allow the instrument to purge for three5-minute samples with zero seconds hold time. If you have ahold time set with a filter, the pump stopping and starting canpush particles back into the optics causing counts.6. In accordance with JIS standards, there should be no morethan 1 particle counted at any size in the middle 5-minutesample.7. Remove the zero filter and put the inlet back on; theinstrument is now ready for operation.Operation 3-3

Note: If the instrument does not go to zero (1 particle isallowed), refer to Chapter 6, Troubleshooting, foradditional information.Warm-up TimeAn initial warm-up period of 15 minutes is recommended beforesampling with the Model 9303. The warm-up period allows timefor the optics to reach a steady-state temperature. This will resultin more repeatable results. Neglecting the warm-up time mayresult in an overestimation of particle size (approximately 10percent). Neglecting the warm-up time will not have a significanteffect on particle concentration; therefore, a zero count can still beperformed without waiting for the warm-up period.Main Menu and Basic OperationPress Menu on the Default Screen to display the Main Menu.Main MenuMAIN MENUSettingsSample MenuBuffer MenuUtility MenuMain Menu3-4 AEROTRAK Handheld Airborne Particle Counter
