If you are not trained in the use of Hi-Pot testers, please do not use one
until you have instruction in the dangers of and proper use of this
instrument. They are designed to deliver HIgh-POTential voltages. They are
dangerous and can and will deliver LETHAL voltages.
BE CAREFUL and know how and what you are doing.
