ENVIRONMENTAL EFFECTS
Temperature
Under normal operating conditions 32º F to 105º F (0º C to 41º C), the
unit's microprocessor and temperature circuit will compensate for
variations in temperature. The temperature during storage and shipping
should not reach below -29º F (-34º C) or above 160º F (71º C).
If the
unit has been stored at other than normal room temperatures, allow unit
to stabilize at room temperature for 15 to 30 minutes. Unit will stabilize
quicker if turned on.

multifunctional unit's microprocessor makes it
unnecessary to recalibrate during minor altitude changes. Please verify
calibration if used over 5,000 feet.
Note:
If readings do not seem accurate, recalibrate the unit
.
Vibration
It is recommended that the unit be used in a stable position to prevent the
display reading from fluctuating.
Note:
Unit will not withstand excessive shock or vibration.
Relative Humidity/Water Vapor
The relative humidity (RH) of the gas being sampled will affect the
reading being displayed. As the RH increases, the sample gas becomes
diluted with water vapor. This decreases the percentage of all gases
measured including oxygen. Gases from high-pressure cylinders and
oxygen concentrators are basically dry (< 0.5% RH). Gas measured after
a humidifier or that has a high RH can cause a reading up to 10% lower
than the actual reading.
Note: For accurate results, never measure oxygen percentage downstream
from a humidifier. This can damage the unit.
