There are potentially hazardous voltages (200 V for HPSMU, and 100 V for
MPSMU/HRSMU/ASU) present at the Force, Sense, and Guard terminals of
Agilent B1500A. To prevent electrical shock, the following safety precautions
must be observed during the use of the B1500A.
• Use a three-conductor AC power cable to connect the cabinet (if used)
and the B1500A to an electrical ground (safety ground).
• If you do not use the 16442B test fixture (B1500A-A5F), you must install
and connect an interlock circuit that opens the Interlock terminal when
the shielding box access door is opened.
• Confirm periodically that the interlock function works normally.
• Before touching the connections on the Force, Guard, and Sense
terminals, turn the B1500A off and discharge any capacitors. If you do
not turn the B1500A off, complete all of the following items, regardless of
the B1500A settings.
• Press the
Stop
• Confirm that the High Voltage indicator is not lit.
• Open the shielding box access door (open the Interlock terminal).
• Discharge any capacitors connected to an SMU.
• Warn persons working around the B1500A about dangerous conditions.
