Temperature Continuity Check
1. Disconnect the connectors for the vaporizer heater, the top, bottom
and rear chamber heaters, and the door heater.
2. Using an DVM, verify the impedance and continuity of each heater.
3. Reconnect the heaters and proceed with the heater tests.
Vaporizer Heater Voltage
1. Insert a cassette and start an empty chamber cycle.
2. Connect a DMM to the injector valve vaporizer heater connector.
Verify the voltage measured is between 20-24 VAC during the first 5
minutes of the vacuum cycle.
Door Temperature
1. Check the voltage on the door heater to verify that it is powered, and
after a few minutes, verify by touch that the heater is functioning.
2. With a Fluke model 80T-150U, or equivalent, measure the door
temperature at the back surface of the door in the lower right corner
(when viewed from the front), 40 mm in from the edge.
3. During the diffusion stage, the door temperature should measure 46°
C ±2°C.
4. For STERRAD
100 S
Systems, measure the temperature during the
second injection stage.
Chamber Temperature
1. Check the voltage on each of the three heaters to verify that they are
powered, and after a few minutes, verify by touch that each of the
heaters is functioning.

Note: The voltages depend on the type of unit being tested:
208 machines have 120V; 380 have 220 V and 415 have
240V.
2. With a Fluke model 80T-150U, or equivalent, measure the chamber
temperature adjacent to the thermistor located by the chamber rib.
3. During the diffusion stage, the chamber temperature should measure
46°C ±2°C.
