High Voltage Shock Hazard
Agilent B2900 can force dangerous voltages (±210 V) at the High Force, Guard, and
High Sense terminals. To prevent electric shock hazard, the following safety
precautions must be observed during the use of Agilent B2900.
• Use a three-conductor AC power cable to appliance coupler (inlet) and the
instrument to an electric ground (safety ground).
• Prepare shielding box which covers interface to a device under test and equipped
with interlock circuit that opens when the door is opened.
• 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 High Force, Guard, and High 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’s settings.
• Terminate source output by pressing the On/Off switch, confirm that the
On/Off switch turns off.
• Confirm that the High Voltage indicator is not lit.
• Open the shielding box access door (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.
