Operating the EntryRAE
3.1 Connect the calibration adapter to the EntryRAE and put a regulator
(500 cc per minute flow rate) on the 4-gas mix cylinder.
3.2 After “Span Cal?” appears on the display with the
CO, H
2
S, and LEL sensors indicated, press
Y.
3.3 Turn the gas all the way on.
3.3 Connect the open end of the calibration
adapter to the regulator. The monitor starts to
countdown from 70 seconds.
3.4 When the countdown timer reaches zero, turn
off the gas, and disconnect the calibration
adapter from the regulator.
3.5 Compare the readings displayed to the span
gas values indicated on the gas cylinder. The
readings should closely agree with the span gas
values.
