OPERATION
Power up by depressing the ON/OFF switch.
Immediately after turning on power, all the
segments of the display and all of the indicators
will be on. After one second the display will show
the actual temperature and the actual temperature
indicator light will be lit. If the setpoint temperature
is greater than the actual temperature, then the
heater on lamp will be on or start to flash. If it
flashes, then the actual temperature is near
setpoint temperature.
To display any TEMPERATURE VALUE - With the
use of either the SET TEMP/CAL key or the HIGH/
LOW LIMIT key, any temperature value can be
displayed. To view the set temperature, press the
SET TEMP/CAL key once. The green indicator for
the set temperature will light. If no other keys are
pressed, within 5 seconds, the display will
automatically return to the actual temperature. To
view the calibrate temperature, press the SET
TEMP/CAL twice while the display is showing the
actual temperature. The same sequence of key
operation is true for the use of the HIGH/LOW
LIMIT key.
To change the SETPOINT TEMPERATURE -
Press the SET TEMP/CAL key once. Then press
the UP or DOWN arrow key until the desired
temperature is displayed. When continuously
pressing either the UP or DOWN keys, the display
will begin to change rapidly. With a little practice,
one will become accustomed to this. After the
desired set temperature is achieved, then press
the ENTER key. The display will then return to
showing the actual temperature. If the ENTER key
is not pressed, the expected new set temperature
will not be accepted and the incubator will control
at the previous set temperature.
To CALIBRATE the INCUBATOR - The incubator
is calibrated at the factory for use over a wide range
of temperatures. Due to the slight non-linearities
in the control system, it may be necessary to make
the display match a calibrated thermometer's
reading, even though the difference might be only
a few tenth's of a degree.
The CALIBRATE key should be used ONLY to
match a stable incubator's actual temperature to
the calibrated thermometer.
Place a calibrated thermometer or the probe of one
at the center of the third shelf of the incubator.
Select the SETPOINT you wish to run the unit at.
Allow the unit to run for at least an hour after it
reaches the setpoint, before you perform the
calibration.
NOTE
IF POSSIBLE PLACE THE THERMOMETER INTO A
LIQUID FOR STABILITY.
To perform calibration, press the SET TEMP/CAL
twice. The green calibration indicator should be
lit. Then press either the UP or DOWN arrow keys
to make the display match the noted thermometer
reading. After the satisfied display is achieved,
press the ENTER key. The display will then return
to showing the newly calibrated actual
temperature.
To change the HIGH TEMPERATURE ALARM
SETPOINT - After selecting a setpoint
temperature, the HIGH TEMPERATURE ALARM
SETPOINT automatically defaults to 1° higher than
the setpoint that was entered. This 1° default
difference can be overridden if the user wishes to.
The following paragraph describes this.
Press the HIGH/LOW LIMIT key once. The green
"High Temperature alarm/Set Point" indicator
should be lit. Use the UP or DOWN arrow keys to
select your limit value. Then press the ENTER key.
If the HIGH LIMIT value you have selected is below
the operating SETPOINT TEMPERATURE, the
incubators' alarm will activate
To change the LOW TEMPERATURE ALARM/
SETPOINT - After selecting a setpoint
temperature, the LOW TEMPERATURE
SETPOINT automatically defaults to 1° lower than
the setpoint that was entered. This 1° default
difference can be overridden if the user wishes to.
The next paragraph describes this.
