Particulate Zero Calibration Prior to calibrating, ensure the impactors are well-greased with an applied thin-film of silicone grease. (Please see “Impactor Care” on page 10 or EVM series user manual.)1. Attach the Zero/HEPA filter and tubing into the turret. Rotate the turret to PM. 2. Select Calib...

Page 5 - NOTE: in order to measure; Logging VOCs

Volatile Organic 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. A PID sensor error will appear indicating: (1) if the sensor n...

Toxic and Carbon Dioxide Span Calibration To perform a span calibration with a specific 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. ; NOTE: The range for the CO 2 sensor...
