Operation and Calibration
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 desired. Allow the unit
to run for at least an hour after it reaches the setpoint, before calibration is
performed.
Note
If possible, place the thermometer into a liquid for stability.
s
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 desired. 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 incubator alarm will activate.
Caution
If the default high temperature alarm setpoint (1°C above
setpoint) is increased, the new alarm temperaure value will remain valid
until power is removed from the unit (turning off the power switch,
unplugging or power failure). When power is restored, the alarm setpoint
will revert back to the default.
s
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 desired. The following paragraph describes
this.
Press the High/Low Limit key twice. The green "Low Temperature
Alarm/Setpoint" indicator should be lit. Use the UP or DOWN arrow
keys to select your limit value. Then press the ENTER key. If the LOW
LIMIT value you have selected is above the operating setpoint
temperature, the incubator alarm will activate.
