one battery pack manufacture may require a 3.0 volt under voltage threshold while another may require 2.5 volts for the same battery pack type. Third, when the cells in one battery pack are unbalanced (e.g., after many charging and discharging cycles) a traditional bleeding method can be unde...
The control of the heater circuit in wideband sensors is more intricate than for traditional sensors. The heat at the sensor has to be maintained within a specified range and the heater is usually controlled using PWM. The heater failing in a wideband sensor is equivalent to the whole sensor ...
Worst case load temperature shall be continually monitored during test by indicators or recorders reading the monitoring sensor(s). Direct heat conduction to specimens shall be minimized. 3. PROCEDURE. Specimens shall be placed in such a position with respect to the airstream that there is ...
