High Voltage Shock Hazard
Keysight B1507A can force dangerous voltages (±3000 Vdc for HVSMU and ±100
Vdc for MPSMU) at the Force, Guard, and Sense terminals. To prevent electric
shock hazard, the following safety precautions must be observed during the use of
Keysight B1507A.
• Connect the instrument to an electrical ground (safety ground) by using
three-conductor AC power cable.
• Before performing measurement, connect the interlock circuit to the Interlock
terminal of this instrument.
• Confirm periodically that the interlock function works normally.
• Before touching the connections of the Force, Guard, and Sense terminals, turn
the instrument off and discharge any capacitors of the measurement path. If you
do not turn the instrument off, complete “all” of the following items, regardless
of any instrument settings.
• Terminate measurement by pressing the Stop key, confirm that the
Measurement status indicator is not lit.
• Confirm that the High Voltage indicator is not lit.
• Open the Interlock terminal.
• Discharge any capacitors if the capacitance is connected to an SMU.
• Warn workers in the vicinity of the instrument about hazardous conditions.
