Section 1 Safety Guidelines WARNING Normal use of test equipment exposes you to a certain amount of danger from electrical shock because testing must sometimes be performed where exposed voltage is present. An electrical shock causing 10 milliamps of current to pass through the heart will stop most human heartbeats. A voltage as low as 35 volts DC or AC (RMS) should be considered dangerous and hazardous since it can produce a lethal current under certain conditions. -
