5. Remove the shorting block from jumper JP2 and return it
6. Replace the cover (see procedure on page 6).
Calibration
This section describes the calibration verification procedure
and calibration adjustment procedures.
Verification Procedure
A quick but approximate calibration verification can be done
by supplying the unit with outside air and letting the reading
stabilize. CO 2 concentrations in outside air are typically
between 375 and 450 ppm.
A more accurate calibration check requires the use of
calibration gas of known concentration. 2000 ppm
calibration gas is recommended A calibration kit is available
from the factory.
To verify the Model 310e's calibration, proceed as follows:
1. Remove the front cover of the unit (see procedure on
2. If there is no display on the unit being calibrated, connect
3. Remove the dust cover from the calibration nipple, attach
4. If the reading differs by less than ± 50 ppm from the

a current or volt meter to the analog output terminals.
Check the setting of the analog output selector (see
Figure 2 on page 4) to determine whether the unit is set
for voltage or current output.
a flexible tube and establish a flow of between 50 and
100 cc/min (0.002 to 0.004 SCFM) of calibration gas
through the sensor. Allow approximately two minutes
for the reading to stabilize.
known concentration of the calibration gas, no adjustment
is recommended; proceed directly to step 7.
Otherwise note whether the shorting block at jumper
JP5 is covering both pins or only a single pin, then
