Introduction
Thank you for selecting the Extech Instruments Model VPC300 Particle Counter with Camera.
The VPC300 has a Color TFT LCD display, a 74MB internal data storage bank, a micro-SD memory card slot for capturing images and video for viewing on a PC, and a built-in 320x240 pixel camera for capturing stills/video of test locations. The VPC300 offers quick and accurate readings for particle count, air temperature, most surface temperatures, and relative humidity. The VPC300 also offers a Dew Point and Wet Bulb temperature calculation geared for energy efficiency and environmental protection applications. Supplied PC software allows the user to generate reports based on records data, images, and video.
This device is shipped fully tested and calibrated and, with proper use, will provide years of reliable service. Please visit our website (www.extech.com) to check for the latest version of this User Guide, Product Updates, and Customer Support.

Operation
Power ON-OFF
Press and hold the power button to switch the instrument ON or
OFF.
Important Notes
Note: Operating the particle counter with the isokinetic probe cap in place will damage the pump and other internal components.
Note: Electrical noise, sensor leakage, or other interference may cause the VPC300 to show incorrect particle count data.
Getting Started
When the meter powers ON, the Particle Counter icon is displayed at the center of the LCD and the date, time, and battery status can be observed on the top row of the LCD. Three bottom row options are also displayed and can be selected using the Function keys (F1, F2, and F3) as shown below. These are explained in greater detail later in this user guide:

Sequence of Operation
To ensure that you measure the amount of particles accurately, perform this sequence of operation.
1.Zero the particle count sensor
2.Setup your counter for proper operation. Sample time, mode, cycle, and interval.
3.Run your test cycles and evaluate the results.
Basic Operation
Press and hold the ON/OFF button for 3 to 5 seconds until the display illuminates to power on the meter.
Press the enter button (
) to get to setup mode. Press F3 to enter settings mode.
Set each parameter to your preferred setting by pressing ENTER to enter each parameter. Then press ENTER to enable editing of each parameter. Press ESC to exit parameter setup.
Sample Time: Length of time each test runs (3 to 60 seconds)
Start Delay: Duration of time from RUN to actual start of test. (3 to 100 seconds) Channel Display: Particle sizes displayed during test.
Ambient Temp/RH: Allows the display of the air temp and %RH values Sample Cycle: Number of test cycles to run (1 to 100)
Sample Mode: Cumulative, differential, concentration Interval: Test cycle delay measured in seconds.
Level Indication: Particle level selection (highlighted on display) Press ESC to return to testing screen
Press RUN/STOP to start the automated test sequence.
