5. STAT IM 2000S Calibration
1. Adjust Press! will appear in the display and the PO value will flash. The PO value can only be
adjusted while it is flashing.
(PPP.P) Actual chamber pressure in kPa.
(PO) Chamber pressure hexadecimal offset value
(TTT.T) Theoretical pressure calculated from the actual chamber temperature.
(CO) Chamber temperature hexadecimal offset value
(CCC.C) Actual chamber temperature in °C
2. By using the lefthand arrow keys, adjust the pressure offset PO (at atmospheric pressure) until
the reading on the LCD display matches the external pressure reference meter's reading. The
PO field will then show the new pressure offset.
NOTE: This has to be done within 30 seconds.
3. After 30 seconds, the calibration cycle will continue by entering the heating up phase and the
PO will STOP flashing and the CO value will flash. The CO value can only be adjusted while it
is flashing.
4. During calibration, the unit will run a normal cycle.
5. Allow the chamber to reach the sterilization temperature. As pressure builds in the chamber,
check for leaks in the cassette, associated piping and fittings. A steam leak in the system
will introduce errors in the measurement and will result in improper calibration and may
compromise sterilization conditions.
6. When Adjust Temp! appears on the display, (see below) and you are confident that the
readings are stable, the chamber thermocouple offset CO can now be adjusted using the
using the righthand arrow keys below it until the reading on the LCD display (as displayed in
the CCC.C field) matches the external temperature reference meter's reading. The CO field will
then show the new chamber temperature offset.
IMPORTANT NOTE: When the initial pressure and temperature readings have been adjusted,
and to ensure equilibrium of the calibration, compare the measured chamber pressure (PPP.P)
and the calculated chamber pressure (TTT.T) displayed on the LCD. They should be within
1 kPa of each other during equilibrium.
