Abstract
A volt meter and a current meter may measure a voltage and a current for the calculation of power consumption. A controller may calculate the power consumption when a heating element is activated and when the heating element is deactivated. Based on the power consumptions when the heating element is activated or deactivated, a failure condition may be determined.
Claims15
An apparatus comprising:
- a volt meter to measure a voltage;
- a current meter to measure a current;
- a heating element to apply heat;
- and
- a controller coupled to the volt meter, the current meter, and the heating element, wherein the controller is to:
- calculate a first power consumption with the heating element deactivated, the calculation of the first power consumption based on the volt meter and the current meter;
- calculate a second power consumption with the heating element activated, the calculation of the second power consumption based on the volt meter and the current meter;
- and
- determine a failure condition of the heating element based on the first power consumption and the second power consumption.

An apparatus comprising:
- a heating element to apply heat;
- a current meter coupled to the heating element, the current meter to measure a current supplied to the heating element;
- and
- a controller coupled to the current meter and the heating element, wherein the controller is to:
- compare an activated current value with a deactivated current value, the activated current value based on a measurement of the current meter while the heating element is activated, the deactivated current value based on a measurement of the current meter while the heating element is deactivated;
- and
- determine a failure condition of the heating element based on the comparison.
