Oven Test Description
The Oven Test is used to evaluate the heating performance of the heating
element.
The heating rate over a 10 K interval from the start temperature is
determined. The start temperature must be between 30 °C and 50 °C, and is
determined as follows:
• If the current oven temperature is below 30 °C, the oven tries to attain a
temperature of 30 °C. 30 °C is used as the start temperature.
• If the current oven temperature is above 30 °C but below 50 °C, the current
oven temperature is used as the start temperature.
• If the current oven temperature is above 50 °C, an error message is
displayed. The oven must then be allowed to cool to below 50 °C before the
test can be run.
Oven Test Evaluation
At the end of the Oven Test, the slope of the temperature rise of the left and
right channels are evaluated. The test passes if both slopes are >=4°C/min.
