If a password is enabled
, you are
prompted to enter one.
1.2.2 Use
Y
to increase the digit and
N
to
decrease the digit.

1.2.4 Press @ and
Y
to enter the password.

2.1 Press
Y
and the calibration begins. The display
YY
counts down from 5 to 1 (5 seconds), at which
time the process is complete.
2.2
Calibration Updating
The monitor is in the process of calibrating the
sensors. As it completes, the display shows
the sensors registering zero (or 20.9% for O
2
),
before it moves to the next step, “Span Cal?”
Using External Zeroing Organic Filters
Use an external zero organic filter (P/N 008-3024-000, 3-pack) if the
ambient air may be contaminated with hydrocarbons. Attach the filter
to the EntryRAE during fresh air calibration. The filter can be used up
to 20 times before disposing. This filter removes most heavier organic
and inorganic compounds, but may not completely remove lighter
compounds such as methane, propane and CO. Note that the filter
should be attached to the EntryRAE before the calibration adapter.
Step Three: Span Gas Calibration for Multiple Sensors
3.0 For this calibration step, the LEL, CO and H
2
S sensors are calibrated
using the 4-gas mix (P/N 600-0050-004).
Step Two: Fresh Air Calibration
The monitor must be in clean ambient air during fresh air calibration.
