Normal use of test equipment presents a certain amount of danger from electrical
shock because testing must 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. Voltage as low as 35 V should
be considered dangerous and hazardous since it can produce a lethal current
under certain conditions. Higher voltages pose an even greater threat because
such voltage can easily produce a lethal current. Your normal work habits should
include all accepted practices that will prevent contact with exposed high
volt-age, and steer current away from your heart in case of accidental contact
with a high voltage. You will significantly reduce the risk factor if you know and
observe the following safety precautions:

Next£º Absolute Encoder Coding
