Altitude Correction
The Model
I-
310e is factory-calibrated for operation at sea
level. When operated at higher elevations, the calibration
must be adjusted by the
amount shown in the altitude
correction table to the right.

Altitude Correction Procedure
To adjust the calibration of a
unit currently calibrated for
sea level operation to a new
altitude proceed as follows:
0
1.0
500
1.02
1000
1.03
1. Let the Model 310e
stabilize to the ambient
CO2 concentration, and
record the reading in
ppm.
1500
1.05
2000
1.07
2500
1.08
3000
1.10
2. Multiply the reading by
the scale factor
corresponding to the
operating altitude in the
altitude correction table.
3500
1.12
4000
1.14
4500
1.16
For instance if the unit is
operating at an altitude of 4000 ft, the scale factor from
the table is 1.14. If the concentration reads 420 ppm,
multiply 420 times 1.14 giving 478 ppm. Adjust the
display to read 480.
5000
1.18
3. Remove the Model 310e’s cover (see cover removal
procedure on page 3).
4.
Note whether the shorting block at jumper JP5 is
covering both pins or only a single pin
, then borrow the
shorting block and slide it over the two pins of jumper
JP2 (see Figure 2 on page 4). Use the 'UP' and 'DOWN'
buttons to change the concentration to the value just
calculated.
