WARNING There are potentially hazardous voltages ( ± 3000 Vdc for HVSMU and ± 100
Vdc for MPSMU) present at the Force, Sense, and Guard terminals of the
instruments. To prevent electrical shock, the following safety precautions must
be observed during the use of instruments.
• Connect the instrument to an electrical ground (safety ground) by using
three-conductor AC power cable.
• Connect the mainframe Interlock terminal to the selector Interlock
terminal by using an interlock cable. Also connect the selector Interlock
terminal to the test fixture Interlock terminal by using an interlock cable.
• Confirm periodically that the interlock function works normally.
• Before touching the connections on the Force, Sense, and Guard terminals
in the test fixture, turn the instruments off and discharge any capacitors. If
you do
not turn the instruments off, complete all of the following items,
regardless of the instrument settings.
• Press the front panel
Stop
key to set the source output off.
• Confirm that the front panel High Voltage indicator is not lit.
• Open the Interlock terminal (open the fixture cover).
• Discharge any capacitors connected to a measurement resource.
• Warn persons working around the instrument about dangerous conditions.
