2) The user now has the ability to scan the barcode on the calibration cylinder. Tap the “Scan Barcode” button and
aim the scanner laser at the barcode on the calibration gas cylinder being utilized. The barcode number will
automatically populate the “Calibration Gas Cylinder #” text box. The user can manually type in the bottle lot#
using the numeric keypad on the Trimble or the user may proceed without entering a cylinder number. This
data will be recorded in the calibration .csv file that is stored during the calibration process.
3) Attach the calibration gas to the Static sample port located on the front of the Envision® gas analyzer and open
the regulator valve. Elkins Earthworks® strongly recommends the use of a Demand Flow regulator. If using a
tunable regulator, use a setting of .5 lpm.
Warning – attach the calibration gas only to the Static port. Do not attach the calibration gas to the Exhaust,
Impact or Available ports. Pressures above 200” H20 on any port other than the static pressure port may result
in a damaged pressure sensor.
