Safety & Warnings
Normal use of test equipment, such as the DC power supply with LED display, exposes users to potential electrical shock hazards, especially when testing in environments with high voltage. Electrical shock can be dangerous, with as little as 10 milliamps of current passing through the heart being potentially lethal. Voltages as low as 35 volts DC or AC RMS should be treated as hazardous. Users should adopt safe work habits to avoid contact with high voltage and steer current away from the heart in case of accidental contact.
Specific safety precautions include:
1. While the DC output of this power supply poses little shock danger, certain test conditions can create high voltage shock hazards:
a. A serious shock hazard exists if the equipment under test is a “hot chassis” type unless it is unplugged or specific precautions are followed.
b. If the equipment under test is powered and uses high voltage, the power supply outputs may float to the connection potential. High voltage may appear unexpectedly in defective equipment. Do not float the power supply output to more than 500 volts peak with respect to chassis or earth ground.
c. If the equipment under test is off but uses high voltage in normal operation, discharge high-voltage capacitors before making connections or tests, as some circuits retain high voltage after being turned off.
2. Use only a polarized 3-wire AC outlet to ensure the power supply chassis, case, and ground terminal are connected to a good earth ground, reducing electrical shock risk.
