Pascal settings.
2. Place 500 mL water inside the Pascal pan followed by a 250 mL bath of water
containing a slide rack with 24 slides.
• Place a Steam Monitor Strip on the bath container.
• Close the Pascal lid and press the “Start/Stop” button.
3. When the SP1 temperature is reached and the alarm sounds verify the digital
display temperature is 126–128 ºC and chamber pressure is 21–23.4 pounds per
square inch (psi). If these parameters are within this range then the Pascal should
be considered to be within calibration limits for the High Temperature Calibration
check point. If the temperature and the pressure are not within the above range,
perform the following adjustment:
• Turn the power switch to the off position.
• Turn it back on while pressing the Up
and Down arrows at the same
time.
• Confirm all 6 LEDs are illuminated; this indicates that Pascal is in calibration
offset mode.
• Press the “Display Set” button one time.
• Adjust the digital display temperature reading by using Up
or Down
arrows to match the pressure that is displayed on the Pascal pressure gauge to
the corresponding temperature recorded on the Pressure-Temperature
Calibration Chart below.
• Note The arrow button may need to be pushed and held with consistent
pressure until the temperature changes. Work quickly as the
temperature and pressure are decreasing.

One pound force per square inch ( 1 psi) equates to 6.895 kPa (kiloPascals), conversion factor provided by United
Kingdom National Physical Laboratory.

Turn the Power off, and wait for Pascal to cool down to room temperature, i.e.
<27 °C. Cold water can be used to reduce the device’s temperature for this step.
