Installation
WARNING There are potentially hazardous voltages ( ± 3000 Vdc for HVSMU and ± 100
Vdc for MPSMU) present at the Force, Guard, and Sense 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, Guard, and Sense terminals
in the test fixture or the shielding box, 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 or the shielding box
access door).
• Discharge any capacitors connected to a measurement resource.
• Warn persons working around the instruments about dangerous
conditions.
