2. While the display is blinking, the setpoint will be displayed and available to be
changed, using the UP
( S )
or DOWN
( T )
arrow key.
3. If no arrow is pressed within five seconds, the blinking will stop and the display
will revert to displaying the measured parameter within the incubator chamber.
5.4 Calibrating the Controls
1. Simultaneously push and hold both the UP
( S )
and DOWN
( T )
arrow keys until
the decimal points in the display begin to blink.
2. While the decimal points are blinking, the UP

5.5 Humidification
NOTE:
Use distilled water only. Never use deionized water!
Humidification of the unit is achieved by evaporation of the water from the chamber
humidity pan placed in the bottom of the incubator. Near saturation humidity is
obtained by filling this stainless steel humidity pan with
distilled water only and
allowing this water supply to warm and evaporate.
Do not try to replace or line this humidity pan with any plastic, glass or other metals.
Only 300 series stainless metals are acceptable for this humidity pan.
Do not use corrosive chemicals including copper sulphate or chlorine in the pan or
chamber as damage may occur.
Use of disinfecting chemicals in the humidity pan can change the surface tension of
the reservoir water, thus preventing evaporation and proper humidification of the
chamber.
At least once a week, the water should be changed in the pan and the pan should be
cleaned to help control contamination and to maintain proper surface tension.
