It's not perfectly clear what you mean by "false readings."
A polygraph test makes measurements of certain quantities. Assuming the equipment is working properly, these can't actually be "false", they are what they are. They may be invalid because it was hooked up wrong, or because the machine is not working right.
The interpretation of the readings is done by a person, and it's certainly possible for that person to reach a false conclusion.
