The control holds for a period of time, allowing
pressure to stabilize, read the pressure on the
transducer due to the head of water in the chamber,
and set the calibration point automatically. No
adjustments are necessary by the technician. Unit

• Temperature Calibration
Temperature calibration is not normally necessary on
SYSTEM 1E Liquid Chemical Sterilant Processing
System.
NOTE: A calibrated temperature measuring device is
required for this procedure.
A container with cold water (5 to 10°C [41 to 50°F]) and
hot water (55 to 65°C [131 to 149°F]) is necessary. The
thermocouple(s) is removed from the mounting
location and is placed in the bath.
NOTE: To make calibration easier, use a spare
thermocouple in place of TC1, TC2 and TC3
thermocouples in the unit. Calibrate each
thermocouple separately. Attach the spare
thermocouple to the proper connection on CN1 while
leaving the threaded end hang free. Free-hanging end
is inserted into cold and hot water baths as directed
during procedure.
