SECTION 2 - THEORY OF OPERATION

(Illustration Below)

The Validator Plus is a fully automatic autoclave which allows an operator to selecrt one of the four preset functions (WRAPPED, UNWRAPPED, PACKS & LIQUIDS) and one user-programmable function (SPECIAL) for sterilization or disinfection. The microprocessor automatically selects the cycle time, temperature and pressure for the selected program.

When the operator depresses the CLEAR/START button (A), the unit will display the selected mode's parameters for four seconds and then fill the chamber with distilled water from the reservoir. When the filling period is complete, automatic activiation of the heating elements builds temperature and pressure for the desired cycle.

At the point that saturated steam conditions are met, the unit will continuously build temperature and pressure to the minimum values of the mode selected.
