    The CO sensor in some models of TSI IAQ monitors may be adversely affected when exposed to isopropyl alcohol vapors released from TSI instruments utilizing condensation particle counting (CPC) technology. For maximum performance, keep CO sensors away from CPC-based instruments utilizing isopropyl alcohol.

  • Page 18: Locating And Identifying Components

    Locating and Identifying Components To add alcohol to the P-T you must first identify and locate the alcohol related components and accessories that are included with the instrument (refer to Figure 1-2, for more information). You will need the following items: •...
  • Page 19 3. Open a bottle of alcohol. Invert the bottle and insert the nozzle end into the alcohol fill capsule as far as possible to make certain that you cannot inadvertently spray alcohol anywhere except down into the capsule. Fill Line Figure 2-4: Alcohol Fill Capsule 4.

Slide it in lengthwise along the instrument, beginning at the back of the instrument (the alcohol wick end) until it stops (do not force it!).

  • Page 24: Attaching The Shoulder Strap (Optional)

    The P-T is now ready to operate. Refer to Chapter 3, “Operation,” for information on starting and operating the instrument. The remainder of this chapter contains information on optional setup routines. Attaching the Shoulder Strap (optional) The P-T includes a shoulder strap, which allows the instrument to be easily carried over one shoulder, and facilitates hands-free operation.

  • Page 25: Connecting The P-Trak To The Computer

    Connecting the P-T to the Computer Each P-T comes equipped with an RS-232 cable and a 25-pin to 9-pin serial cable adapter. One end of the cable is a 25-pin D subminiature connector labeled COMPUTER; the other end is an RJ-45 modular connector that connects with the P-T communications port.

  • Page 26: Connecting The Optional Portable Printer

    4. Select the correct serial port (such as, COM1); then select Test. The software will verify that you have set up the communications port correctly and that it is communicating with the P-T . The system displays an information message indicating whether it was able to establish communications.

  • Page 27: Operation

    Chapter 3 Operation Overview The P-T has three main modes of operation, Survey, Sample, and Data Log. Survey mode: When the P-T is first turned on, it will be in Survey mode which is used to display real-time particle concentration readings, in particles per cubic centimeter (pt/cc).
  • Page 28 The P-T contains liquid isopropyl alcohol, which is absorbed into a porous wick. Under most operating conditions, the alcohol remains absorbed in the wick. However, if the instrument is tilted for a period of time, the alcohol will slowly seep out of the wick. This liquid alcohol may be drawn into the optical chamber, causing false particle counts and possibly flooding the optics.

  • Page 29: Daily Zero Check

    Daily Zero Check Before beginning to sample with the P-T , it is important to verify that the instrument is operating normally. This Daily Zero Check should be performed at least once a day. 1. Turn on the instrument and let it warm up (approximately 60 seconds).

  • Page 30: Main Menu

    Figure 3-1: P-T Keypad and Display Main Menu After the instrument has completed its warm-up countdown, the P-T will automatically go into the Survey mode and the Main Menu will be displayed. 3670 SAMPLE SETUP LOG MODE 1 Figure 3-2: Main Menu Screen (sample) Description Particle concentration, in units of particles per cubic centimeter.

  • Page 31: Particle Concentration

    Particle Concentration The P-T displays the measured particle concentration in units of particles per cubic centimeter (pt/cc). The display updates once per second. The instrument range is from 0 to 500,000 pt/cc. Sample Mode The SAMPLE mode is the default selection on the Main Menu (the reverse highlight indicates that it is selected).

  • Page 32: Changing The Location Label

    Changing the Location Label Once you choose to save the data point in memory, the P-T displays the EDIT LOCATION screen. The instrument gives the data point a default name, starting with “LOCATION 01.” The following screen is displayed. -EDIT LOCATION- LOCATION 01 PRESS ↵...

    Sampling Through Inlet Screen, Tube, and Probe Assembly The standard sampling configuration for the P-T makes use of the inlet screen, sample tube, and telescoping probe. This configuration is the easiest to use and is suitable for a wide range of applications. It has the following features: Advantages Disadvantages/Cautions...

  • Page 48: Sampling Through Inlet Screen Assembly Only

    Sampling Through Inlet Screen Assembly Only The P-T must always be operated with the inlet screen assembly in place. This mesh screen prevents large particles and fibers from clogging the sensitive internal components in the instrument. If desired, you may operate the P-T with only the inlet screen and no sampling tubing.

  • Page 49: Maintenance

    Maintenance Schedule Your Model 8525 P-T Ultrafine Particle Counter needs very little required maintenance. The few items that are suggested, however, should be done regularly, to ensure reliable operation. Table 4–1 lists the factory recommended maintenance schedule.

  • Page 50: Recharging The Alcohol Wick

    Recharging the Alcohol Wick The alcohol wick should be recharged with alcohol at least once a day (depending upon usage). Please see Chapter 2, “Setting Up,” for detailed instructions on recharging the alcohol wick. Alcohol Cartridge The alcohol cartridge holds a reservoir of isopropyl alcohol. A porous wick inside the cartridge is soaked with alcohol.

  • Page 51: Removing The Wick From The Cartridge

    Removing the Wick from the Cartridge To remove the alcohol wick from the cartridge, grasp the cartridge with both hands, with your thumbs near the seam, and firmly apply pressure as if you wanted to break it into two pieces. The cartridge will snap apart exposing the end of the white Alcohol Wick.

    are blocked, clear them by blowing air through the screen. If the screen cannot be 100% cleaned, replace it with a new one. A new screen is included with each new wick. Examine the white alcohol wick. Some light brownish-yellow discoloration of the wick is normal.

  • Page 53: Cleaning Inlet Screen Assembly

    Re-assemble the cartridge. Align the two halves of the alcohol cartridge and press firmly until they snap together. The cleaning/replacement procedure is complete. Cleaning Inlet Screen Assembly The inlet screen assembly protects the instrument from contamination by coarse particles and/or fibers. When the inlet screen is clean, it has almost no affect upon the instrument particle counting.
