- Page 14 One way to determine the source of air particulates in a room is to test the air outside of the room under investigation. Determine the concentration and size of particulates at the air intake to that room. Purge or Zero the particle counter and then measure the concentration and size of particles in multiple areas of the room to be tested, to determine the effectiveness of the incoming air filtration. The air temperature, relative humidity, and CO2 levels are also an important consideration for IAQ as high humidity and lower temperatures can bring about mold creation. If a room is classified as an ISO clean room or clean zone, the counts of particle sizes for that class cannot be exceeded when tested. Refer to the ISO Clean Room Class chart (ISO 14644‐1:1999) for values. The VPC300 is equipped with a still/video camera to directly see the areas under test. Data, images, and video can be stored on up to an 8GB micro‐SD card (not included) or in the meter’s internal 74MB memory. The life of the meter can be maximized by testing only when necessary and securely storing the instrument when it is not in use. Continuous use is not recommended and can shorten the life of the instrument especially in dusty environments. Setting up a common sense maintenance schedule and testing to the schedule will go a long way in lengthening the life of the instrument sensor. PC Interface and Supplied PC software This meter has the capability to connect to and communicate with a PC. A USB cable is supplied and connects to the jack on the meter’s left side compartment. To install and use the software, please refer to the instructions provided on the supplied CD‐...

Page 15: Battery Charging And Replacement
Battery Charging and Replacement When the battery icon appears drained on the LCD or if the meter will not switch ON, the battery must be recharged using the supplied AC adaptor/charger. The charger plug connects to the jack located on the meter’s left side compartment. The battery compartment is located on the rear of the instrument. The battery is a 7.4V Lithium‐ion polymer rechargeable battery. To access the meter’s battery for replacement: On the rear of the meter, remove the Phillips head screw that secures the battery compartment. Open the compartment by carefully lifting the compartment cover. Replace the battery with one of the same type (note that the Micro‐SD card slot is located underneath the battery as explained below). Close the compartment and secure the compartment cover with the Phillips head screw Battery Safety Reminders Please dispose of batteries responsibly; observe local, state, and national regulations. Never dispose of batteries in fire; batteries may explode or leak. Always install a new battery of the same type. Micro‐SD Card Slot (optional) The micro‐SD card slot is located inside the battery compartment underneath the battery. Micro‐SD cards up to 8GB can be inserted in the slot. To access the SD memory card slot: Turn off power to the meter and remove the AC adapter cable if connected. Open the battery compartment as described in the battery replacement section. Remove the battery. Insert a micro‐SD card (8GB max.) in the card slot underneath the battery by lifting up on the metal card holder and placing the Micro SD card in the connector. The pins facing towards the top of the meter. Close the metal holder. Insert the battery and secure the compartment cover before powering on the meter. 15 VPC300‐en‐GB_v1.5 5/15 ... -
