• Water level in the humidity pan
• Frequency of door openings
• The humidity pan located on bottom of chamber versus a shelf.
Caution Incubators equipped with a Thermal Conductivity CO
rely on a constant level of relative humidity in order to accurately measure
and control the CO
The sensor is capable of measuring relative humidity from 10% to 100%
with an accuracy of ±5% above 90%. See Section 2, Calibration, for
Accuracy
details on calibrating the humidity readout.
Warning The Uninterruptible Power Supply is not rated for life-support
applications.
The optional Uninterruptible Power Supply ([UPS] P/N 270078 and
270082) provides a back-up power source for the incubator. When the
batteries are fully charged and the incubator operating at 37°C in an 18°C
ambient temperature, the UPS provides approximately one hour of
uninterrupted power during a power failure. A higher operating
temperature decreases this back-up time, a higher ambient temperature
increases it. This estimated time assumes that the incubator will be already
at its operating temperature and that the incubator door will not be
opened during the back-up period.
The remote alarm contacts will not trip during a power failure while
connected to the UPS until battery power is exhausted. There is however,
an audible and visual alarm when the unit switches to battery operation.
The UPS batteries are fully charged when the unit has been connected to
utility power for a minimum of four hours. The UPS power switch does
not have to be on for the batteries to charge. When battery replacement
becomes necessary, refer to the UPS user's manual.
Caution Use only factory recommended UPS units which produce a pure
sine wave output. Other UPS units could damage the incubator and void
the warranty. Typical facility back-up systems will not effect the efficiency
of the incubator.
