A high PT usually means that there is serious liver damage or cirrhosis. Other things to know: Some patients take a drug called Coumadin (warfarin), which elevates the PT for the purpose of thinning the blood. This is not related to having liver disease because it is the Coumadin causing the PT to be high.
A battery backup, or uninterruptible power supply (UPS), is primarily used to provide a backup power source to important desktop computer hardware components.
High voltage systems. High voltage systems are usually electric baseboard heating systems or other radiant systems powered by electricity. High voltage thermostats are built into the wall and have 2-4 thick wires that come out of the back of the thermostat. These wires connect with wire nuts to corresponding wires coming out of the wall. Only high voltage thermostats have thick, stranded wires coming out of the thermostat itself.
