EVM and User Interface Display Backlight Particulate pump Left arrow key Run/Stop key Indicators Softkey menus Up arrow key Altf key Enter key Right arrow key Down arrow key On/Off and Esc key T urning On/Off and Navigating 1. Press key power on. (Following a splash/welcome screen, the Start screen will appear .

Overview of running measurements Quick Help List: typical gas, particulates,or air quality measuring overview 1. T urn the EVM on and check the battery power . 2. Reset/Clear memory , if necessary ( StartFile System menu). • This will clear out data history before your logging begins to ensure you havesufcientmemoryspace.

Particulate Zero Calibration Priortocalibrating,ensuretheimpactorsarewell-greasedwithanappliedthin-lmofsilicone grease. (Please see “Impactor Care” on page 10 or EVM series user manual.) 1. Attach the Zero/HEP A lterandtubingintotheturret.

Volatile Or ganic Compounds (VOCs) VOCs, air pollution with carbon-containing chemicals, are measured using a Photoionization detector 10.6eV . The EVM is equipped to notify you when maintenance and cleaning is required for the PID sensor .

T oxic Gases The following toxic gases table displays a quick overview of the ranges and the gases needed to perform zero and span calibrations. T ype of Gas Range Res. Zero cal gas Span cal gas Carbon Monoxide (CO) 0 -1000 ppm 1 ppm nitrogen/pure air CO Chlorine (CL 2 ) 0.

T oxic and Carbon Dioxide Span Calibration T operformaspancalibrationwithaspecictoxicgas,pleasereferencethetoxicgas table. For the CO 2 span calibration, the range (or span) should be a sizeable fraction of the selected full scale range of the gas.

T emperature and Relative Humidity Logging/Viewing T emperature and/or Rela tive Humidity The T emperature and Relative Humidity readings are viewable in either the T emp-RH measurement screen or in the Composite screen.

Air Velocity T o view air velocity measurements, perform or verify the following: 1. The air velocity probe is enabled in SetupAUXAir V elocity screen. 2. Connect the air velocity probe and attachment to the EVM unit to the auxiliary Air probe inlet. (See Air Probe inlets diagram in previous section, “Particulate Air Flow”.

Maintenance/Cleaning Sensors Locations The gas sensors are inserted, factory calibrated, and ready for usage upon delivery . (The diagram below is based on the EVM-7 model.) Occasionally , you may have to care for the sensors which will require removing and inserting.

Working with 3M TM Detection Management Softw are DMS Communicating 1. When the EVM is On , plug the USB cable into the EVM and plug the opposite end to the USB port of your computer .
