3. TPI 1020 Overview
3.1 Description
The TPI 1020 is designed to be a small, easy to use and completely portable hand-held particle counter that can provide fast and accurate measurement of particulate contamination in particles per cubic foot (or liter). The TPI 1020 has 5 selectable size ranges of 0.3, 0.5, 1, 2, and 5 micron.
The TPI 1020 contains a laser diode based sensor, Lithium Ion battery pack, vacuum pump, microprocessor electronics, LCD display and user input keys all in one small package. The accuracy of the TPI 1020 is certified according to ASTM and JIS standards and comparable to larger more expensive bench top particle counters. The fast 3-second response of the TPI 1020 makes it especially useful for troubleshooting contamination problems and tracing contamination leaks to the source.
The laser diode based sensor inside the TPI 1020 utilizes a specially designed elliptical mirror for high light collection efficiency and improved signal to noise. Precision optics collimate the laser beam into a thin, very intense beam resulting in increased signal and a high concentration limit of 3,000,000 particles per cubic foot. This high concentration limit allows the TPI 1020 to be used for indoor and outdoor aerosol particulate measurement.

4. Operation
4.1 Iso-kinetic Sampling
The TPI 1020 comes with an iso-kinetic inlet nozzle. The iso-kinetic inlet helps reduce count errors related to the sample flow velocity and the aerody­namics of small particles. When taking a sample of typical indoor or outdoor aerosols the opening of the iso-kinetic inlet should always face upward. The TPI 1020 can be held in your hand or placed on a flat surface with its display facing towards you.
When sampling in an area having constant airflow, such as a clean room, duct, vent or the downstream side of a filter, always face the opening of the iso-kinetic inlet into the air flow. The sampling height will affect the TPI 1020 particle count reading. Taking a sample near the floor can give results several times higher than a sample taken at eye level.
When using the TPI 1020 to find the source of a contamination problem, be aware that not all contamination problems are continuous, some are the result of a short-term event or burst of particles. Locating the source will require taking a number of samples in the same spot.

4.2 Taking a Sample
CAUTION: Never sample smoke, paint spray, oil mist, reactive, or pressurized gasses to avoid damaging the sensor optics.
Press the <START/STOP> button to turn the unit on. The Main screen will appear. The parti­cle counter will automatically display the size and volume settings last used.
Main Screen
Press the <SELECT> button to display the Select screen when the unit is not sampling. Here the SIZE and VOLUME settings can be changed.
Select Screen
Initially the edit cursor is placed at the beginning of the SIZE setting. Press <SELECT> to cycle through the five size selections. Select size range of interest.
When you select a particle size, you are setting a lower size limit for the counter in the TPI
1020. The TPI 1020 will count ½ of the particles of the selected size when a sample is taken, and all particles larger than the selected size. This type of counting is defined as cumulative counting.
The edit cursor will move to the VOLUME setting after 3 seconds of no button presses. Press <SELECT> to toggle the volume setting between CF (cubic feet per minute) and LPM (liters per minute). Select the volume units desired.
The Main screen will be displayed after 3 seconds of no button presses.
After selecting the desired particle size and volume, press the <START/STOP> button to begin a one minute sample. You should hear the internal vacuum pump start running. After 3 sec­onds, (subsequent readings every 3 seconds) a number will appear on the display represent­ing the number of particles per cubic foot (or liter). A progress bar will fill in left to right as the one minute sample is running.
Sample Screen (set for 0.3u and cubic feet)
The results from the 20 3-second samples are then averaged and displayed. The display will hold the average result until the start key is pressed to take another sample or until the unit is switched off. The <START/STOP> key is used to stop a sample at anytime. Any data accumulated is lost when the <STOP> key is pushed.

5.3 Battery Pack
WARNING: There are no user serviceable components inside the TPI 1020. Do not attempt to change the internal battery pack. The wrong battery pack could cause serious damage, a fire, or explosion. The TPI 1020 should be sent to a service center where a factory qualified person would change and properly dispose of the battery pack.
This device contains Lithium Ion battery technology and should only be charged with the supplied 8.4 VDC Lithium Ion Smart Charger unit. Never connect a power source greater than 8.4 VDC to this device.
When the battery is low enough to need charging, a "Battery Low" message is displayed on the display and the pump will not turn on when the <START/STOP> key is pushed.
To charge the battery pack, plug the 8.4 VDC Lithium Ion Smart Charger unit into an AC power outlet. The module is universal and will work with power line voltages of 100 to 240 volts, 50 to 60 Hz. Take the barrel connector on the end of the cord coming from the Charger module and plug it into the charger input socket on the side of the TPI 1020 (See section 2.2 Familiarization). To fully charge a discharged battery pack should take around
2.5 hours.
NOTE: After the batteries are completely charged, the smart charger will stop charging. The next time it is used, it must be disconnected from AC power, and then reconnected to the AC outlet to restart the charge cycle.
The battery pack inside the TPI 1020 when fully charged will power the TPI 1020 for about 12 hours of continuous use. Under normal intermittent or manual operation however, there is considerably less battery drain and up to 30 hours of use is possible.
If the TPI 1020 is to be used powered by its battery pack on a daily basis, connect the charger after every few days of usage, or as needed.

5.4 Flow Rate Test
The sample flow rate of 0.1cfm (2.83 lpm) is set at the factory. However, wear from continued use can degrade the motor and vacuum pump. Variation in the flow rate will reduce the accuracy of the instrument.
A flow calibration kit is available separately that includes everything needed to test and adjust the flow rate. It includes a flow meter, inlet adaptor, and flow adjustment tool.
Testing the flow rate is an easy procedure. It requires a flow meter that is 3% accurate at 0.1cfm. The flow meter must be non-loading (low restriction). The tiny vacuum pump inside the 80340 can be easily loaded down by even a small restriction. Most hot wire and differential pressure types of flow meters are non-loading.
To test the flow rate, connect the flow meter to the inlet nozzle of the TPI
1020. Turn on the TPI 1020, start a sample, and note the flow meter reading. The flow rate should be 0.10cfm (2.83 lpm) 5%.
If the flow is not within this tolerance, it can be adjusted by a trim pot located in an access hole in the side of the TPI 1020 case (See section 2.2 Familiarization). Use the flow adjustment tool that comes with the flow cali­bration kit to make the adjustment. Turn the adjustment pot clockwise to increase the flow and counter-clockwise to decrease the flow.
