SQ21 – MPX CALIBRATION
Select PRESSURE SENSOR CALIBRATION to correct any differences
between the pressure value displayed and the pressure measured with a
reference pressure gauge.
The three counters displayed can be modified and represent:
-
P+ pressure value correction at + 2.10 bar.
-
P0 pressure value correction at 0.00 bar.
-
P- pressure value correction at – 0.80 bar.
In order to determine whether the pressure value displayed is accurate,
you will need to connect the device to an external gauge, allowing a
comparison with the displayed pressure values.
The displayed value can be changed in 0.001 bar steps.
SQ22 – DISPLAY CALIBRATION
With the tip of a pen, press on the central part of each cross to calibrate
the display.
SQ23 – TEST CYCLES
Select TEST CYCLES to display a vertical scroll menu with the following
options:

(ROW version only)
Select NO VACUUM to display the 134°C S cycle start-up screen.
With the command indicated on the left, you can activate the
cycle, which will be performed without the pre-vacuum phase.
After the heating phase, the pressure rise is performed to achieve the
process values of 134°/2.10bar, a condition that will be maintained for 4’.
This special cycle, which has no alarms, is designed to detect any steam
leaks from chamber, door, generator and connected tubes.
SQ24.1 – NO VACUUM (US/CA versions only)
Select NO VACUUM to display the 132°C (270°F) Solid wrapped cycle
start-up screen.
With the command indicated on the left, you can activate the
cycle, which will be performed without the pre-vacuum phase.
After the heating phase, the pressure rise is performed to achieve the
process values of 132°C(270°F)/1.90bar, a condition that will be
maintained for 4 mins.
This special cycle, which has no alarms, is designed to detect any steam
leaks from chamber, door, generator and connected tubes.
