Pascal Handbook

manual for both the factory setting parameters and the instructions on changing

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.

Pressure Temperature Pressure Temperature

13.0 psi 118.0 ºC 18.9 psi 124.0 ºC

13.5 psi 118.5 ºC 19.5 psi 124.5 ºC

14.0 psi 119.0 ºC 20.0 psi 125.0 ºC

14.4 psi 119.5 ºC 20.5 psi 125.5 ºC

15.0 psi 120.0 ºC 21.0 psi 126.0 ºC

15.4 psi 120.5 ºC 21.6 psi 126.5 ºC

15.9 psi 121.0 ºC 22.2 psi 127.0 ºC

16.3 psi 121.5 ºC 22.8 psi 127.5 ºC

16.8 psi 122.0 ºC 23.4 psi 128.0 ºC

17.3 psi 122.5 ºC 23.9 psi 128.5 ºC

17.8 psi 123.0 ºC 24.5 psi 129.0 ºC

18.3 psi 123.5 ºC 25.1 psi 129.5 ºC

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

Kingdom National Physical Laboratory.

4. 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.
