The power of a laser beam is typically measured in watts (W). This measurement indicates how much energy the laser beam is emitting per unit of time.
The blower motor control unit is located on the back of the blower motor. 1. Check fuse. 2. Turn on heat and check for voltage at blower motor. Found voltage replace blower. 3. Check for supply power from the fuse on the red wire going to the blower control unit. 4. Check for a good ground on the black wire on the control unit. 5. Check for control power on the yellow wire from the climate control unit. When you select a fan speed (or the unit selects a speed in auto mode) a voltage that ranges from .4 - 9 volts is sent down the yellow wire to the blower motor control unit. 6. If all these checks are good than change the blower motor control unit. Hope this helps.
Shows that there are errors present in the Heating/Cooling control unit.

It was used to measure the strength of a laser. In the 1960s, razor blades were pretty much similar in shape and a Gillette was a non-standard unit for measuring the strength of a laser beam. The measurement comprised the number of laser blades that a laser device could burn through.
