2-4 TVA2020 Instruction Manual
While operating this instrument in the field, you normally carry the
TVA2020 at your side using the shoulder strap or in a backpack (not
supplied). With the pump on, detector(s) on, and the unit warmed up, you
monitor the area of concern. As soon as the instrument analyzes a sample,
the sidepack displays concentration of the vapor. The display on the
optional enhanced probe duplicates the vapor concentration on the
sidepack display. Using the enhanced probe, you can toggle the display
between detector types by pressing the SELECT button on the probe,
configure to log the survey data by pressing the MENU button, and
backlight the LCD display by pressing the lamp button. The concentration
data is also streamed out from the optional Bluetooth device, if installed
and turned on.
WARNING Charger and USB connections are not allowed in an area
classified as hazardous due to presence of flammable gases or vapors.
WARNING To prevent a potential explosion, do not operate the
instrument with the PID compartment open or FID detector cap
removed.
