NOTES D'APPLICATIONMANUELSLOGICIELFOIRE AUX QUESTIONSshow/hide all answers
- Can I adjust the alarm setpoint without using TRAKPRO software?
No. TRAKPRO software version 3.1 or higher is required to control the alarm and analog output functions. The DUSTTRAK is shipped from the factory with the alarm setpoint at 0.100 mg/m³ and with the alarm function turned "off".
- Can I connect a computer to the DUSTTRAK for continuous monitoring?
Yes. An enhancement made in November 1996 allows the DUSTTRAK to do serial data acquisition using simple ASCII commands. The DUSTTRAK can be set up to provide a reading once per interval (from 0 to 60 seconds) or to output a single concentration reading. Request Application Note ITI-044 for more information.
- Can I leave the Environmental Enclosure out in the rain?
Yes. The case is weather resistant. It can tolerate all weather conditions. It should not be placed in direct contact with the ground.
- Can I measure other particle size ranges with the DUSTTRAK?
Yes. The DUSTTRAK is supplied with inlet conditioners (impactors) that limit the upper size to 2.5 or 1.0 microns. Additionally, the DUSTTRAK is supplied with a 10-millimeter Nylon Dorr-Oliver Cyclone for respirable sampling with a cut-off at 4 microns.
- Can I substitute different tubing to connect the Enclosure's aerosol inlet to the DUSTTRAK inlet?
Using alternate tubing is not recommended. The tubing provided with the Enclosure is special electrically conductive tubing designed to minimize particle transport losses. Use of tubing made from other materials may result in low readings. The Environmental Enclosure Accessory Kit (P/N 801566) includes a replacement tube along with other components.
- Can I turn the DUSTTRAK On/Off without opening the Enclosure through the RS-232 port in the Enclosure?
Although the DUSTTRAK will respond to remote queries through the RS-232 port, it cannot be switched On/Off remotely. The instrument can, however, be set to record data a predetermined times through the Log 2 or Log 3 modes. Refer to the DUSTTRAK Operation and Service manual for information on how to do this.
- Can I use an AC power source to run the DUSTTRAK inside the Enclosure?
There are currently no options available from TSI for using an AC adapter along with the Environmental Enclosure. The DUSTTRAK AC adapter (P/N 2613033) is not rated for outdoor use.
- Can I use another battery charger to charge my battery packs?
This is not recommended. The charger provided with the Environmental Enclosure (part no. 801564) has been designed to match the needs of this battery pack. Using another charger could result in severe damage to the battery. The charger charges at 7.5 volts, 850 mA and automatically stops when full charge is reached. The battery is a 6-volt sealed lead-acid type with a rating of 10 amp-hours.
- Can the Environmental Enclosure perform PM10, PM2.5, or PM1.0 sampling?
Yes. The external inlet will effectively sample particles up to 10 microns. Your choice of DUSTTRAK inlet (impactor) will determine which PM sample is taken.
- Does direct sunlight cause a heat problem within the Enclosure?
No. The light gray color acts as a thermal insulator. This will prevent an increase of the temperature inside the Enclosure above the ambient temperature. The thermal mass of the Enclosure will also dampen temperature fluctuations normally experienced outdoors.
- How can I convert the DUSTTRAK'S 0-5 VDC analog output to a current output such as 4-20 mA?
By using a standard signal converter that converts 0-5 VDC to 4-20 mA. See TSI Application Note ITI-073 for additional information.
- How does sampling in high humidity affect the readings obtained from the DUSTTRAK?
Relative humidity higher than 80 percent can cause particle concentration readings to be biased high from the actual concentration of dry particles. The amount that an aerosol's mass concentration increases due to water absorption is a complex function of the particle's material and the atmosphere's absolute humidity (i.e. specific humidity). This humidity effect can bias the DUSTTRAK's readings up to 60 percent high in the most extreme conditions of high temperature and high relative humidity.
- How high should I have my Enclosure off the ground when sampling?
The Enclosure should be kept a reasonable distance off the ground to prevent any major air flow disturbances caused by the ground from affecting the sample obtained. TSI recommends mounting the Environmental Enclosure 3 to 4 feet off the ground.
- How long can I run the DUSTTRAK on the external battery pack without charging it?
A fully charged battery will run for up to 60 hours under ideal conditions. The battery pack has an automatic voltage cut-off which prevents the battery from becoming deeply discharged. To prolong the life of your battery, you should recharge it every 24 hours.
- How long is the warranty on the DUSTTRAK monitor?
The DUSTTRAK is warranted to be free from defects in workmanship and material for a period of twenty-four months from the date of shipment to the customer. See the Operation and Service Manual for detailed warranty terms and conditions.
- How often do I need to clean the aerosol inlet?
The inlet does not easily clog with debris and can be operated confidently for an extended period of time without cleaning under most conditions. If the Environmental Enclosure is being operated in high concentrations (more than 20 mg/m3 the inlet may need frequent cleaning. The inlet should be kept clean to prevent debris from constricting the flow. The best way to clean the inlet is to unscrew it from the Enclosure and blow it out from its threaded end (base). If readings are abnormally low make sure that the inlet is clean, and blow it out periodically as a precautionary measure.
- How often is calibration required?
TSI recommends returning the instrument to the factory for cleaning and calibration on an annual basis. Turnaround time is typically 2 to 3 working days after receipt of the unit with proper documentation. Recommended user maintenance schedules for routine cleaning, filter replacement, and zero check is covered in the Operation and Service Manual.
- What happens if the battery becomes fully discharged while sampling?
When the voltage of the external battery pack reaches 5.1 volts or less, the battery pack will automatically shut off. If the DUSTTRAK does not have an auxiliary power source (internal C-cell size batteries), it will turn off and the sample will be terminated. All data stored in the internal memory will be left intact due to the DUSTTRAK's internal lithium battery back-up feature.
- What is the analog output resolution in volts per milligram/m³?
The analog output resolution is a function of the scaling range selected. See TSI Application Note ITI-073 for more detailed information.
- What is the aspiration efficiency of the Environmental Enclosure?
- What is the maximum particle concentration that the Environmental Enclosure can handle?
The Environmental Enclosure adds no constraints on the DUSTTRAK and can be used in particle concentrations up to the DUSTTRAK's maximum of 100 mg/m3.
- What kind of tripod do I need to mount the Enclosure?
Any style of sturdy industrial tripod will work as long as it utilizes a connector with a 5/8 inch x 11 thread (flat). This type of tripod is often used for surveying instruments. One possible vendor is:
Sokkia Measuring Systems
Look on their web site at http://www.sokkia.com for the nearest distributor.
Although tripod mounting the Environmental Enclosure is recommended for most applications, other mounting options are acceptable. Mounting on a pole/rail/table/etc. will work suitably.
- Where is the best place to set up the Environmental Enclosure?
The Environmental Enclosure can be set up and operated effectively in most outdoor locations. Rooftops, bench tops, fields, and ditches are all examples of places you could place the Environmental Enclosure. The inlet tube must be oriented substantially perpendicular to the ground and in a place where there are no obstructions that will disturb the air flow around it. Lood for a location with consistent, stable wind conditions, and without swirling turbulence. Trees, buildings, or other large objects will cause flow distrubance around the aerosol inlet and adversely affect readings. The best rule of thumb is to put it in the most open area available.
- Which DUSTTRAK size-conditioning inlets can I use in conjunction with the Environmental Enclosure?
The Environmental Enclosure is compatible with the 1.0, 2.5, and 10.0 micrometer size-conditioning inlets (impactors) supplied with the DUSTTRAK. The TSI-supplied cyclone (P/N 800665) is not compatible with the Environmental Enclosure.
- Will running the flow through the additional aerosol inlet (impactor) change the flow rate to the DUSTTRAK?
No. The pressure drop is minimal through the omnidirectional aerosol inlet on the Environmental Enclosure and causes no change in the volume of air that the DUSTTRAK is sampling. Be sure to set the DUSTTRAK flow rate to 1.7 L/min before installing it in the enclosure. The sampling inlet on the Enclosure is specifically designed for a flow rate of 1.7 L/min.
