STATIM 7000 Service Manual – S Class Calibration

9. VCAL value should be adjusted so that the VVV value is the same as the line voltage
measured by the reference voltmeter connected to the power line (same power outlet
where Statim power cord is plugged in). Calibration should be done within ±2%.
10.This calibration phase lasts at least 30 seconds and it ends either by pressing the
R&P button or automatically when the unit moves to the Conditioning phase. When
the Voltage Reading calibration phase ends the screen moves to the main calibration
screen, see below (see item 5 above for a description of this screen):
11.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 non-sterile instruments.
Keypad functions at this time:
Unwrapped Key:
increment current selected offset (flashing offset)
Wrapped Key:
decrement current selected offset (flashing offset)
Rubber and Plastic Key:
select between PO and TO
Stop Key:
end chamber thermocouple calibration
12.During calibration the unit will run a normal cycle except the beginning of the holding
phase (sterilization phase) when for ten consecutive times all the devices are turned
off for approximately 10 seconds to facilitate the calibration process. During these
periods the chamber temperature could go down to 131°C. After these ten “calm”
periods the unit will resume normal operation (see the TIP below for checking the
calibration during normal operation).
13. During these “calm” periods observe the chamber temperature as displayed on the
reference thermometer and on the lower right side of the Statim LCD (CCC.C value).
Adjust the TO value by using the Unwrapped and Wrapped keys until the displayed
temperatures match to within ± 0.2
°
C. Please note that Chamber Temperature Offset
TO flashes when it is allowed to be adjusted. If PO flashes press R&P key to select
TO field. Adjust TO when the display shows:
14. When chamber pressure is higher than 115kPa the PO field will switch to indicate
the POS – Pressure Offset Sterilization. During the sterilization phase, after adjusting
the temperature, press R&P key to select the PO field (PO field will be flashing) and
using the keypad, adjust the pressure offset POS to match the external meter
pressure indication within ±1 kPa.
NOTE
: POS should not be more than 14 counts (7kPa) away in any direction from
POA.
