SAFETY
When testing with DC, always discharge the capacitance of the item under test and
anything the high voltage may have contacted--such as test fixtures--before handling it or
disconnecting the test leads.
HOT STICK probes can be used to discharge any capacitance in the item under test as a
further safety precaution. A hot stick is a non-conducting rod about two feet long with a
metal probe at the end which is connected to a wire. To discharge the device under test,
two hot sticks are required. First connect both probe wires to a good earth ground. Then
touch one probe tip to the same place the return lead was connected. While holding the
first probe in place, touch the second probe tip to the same place where the high voltage
lead was connected.
KEY SAFETY POINTS TO REMEMBER
Keep unqualified and unauthorized personnel away from the test area.
Arrange the test station in a safe and orderly manner.
Never touch the product or connections during a test.
In case of any problem, turn off the high voltage first.
Properly discharge any item tested with DC before touching connections.
