HIGH VOLTAGE SHOCK HAZARD
The Agilent 4155C/4156C/41501B can force dangerous voltages (200 V for
HPSMU, and 100 V 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 the Agilent 4155C/4156C/41501B.
•
Use a three-conductor AC power cable to connect cabinet (if used) and Agilent
4155C/4156C/41501B to an electric ground (safety ground).
•
If you do not use Agilent 16442 Test Fixture, make sure to connect the INTLK
terminal to a switch that turns off when the shielding box access door is opened.
•
Confirm periodically that INTLK function works normally.
•
Before touching the connections of the force, guard, and sense terminals, turn
the Agilent 4155C/4156C/41501B off and discharge any capacitors whenever
possible. If you do not turn the Agilent 4155C/4156C/41501B off, complete
"all" of the following items, regardless of any Agilent 4155C/4156C/41501B
settings.
•
Terminate measurement by pressing Output key, confim that the Output
status indicator is not lit.
•
Confirm that the HIGH VOLTAGE indicator is not lit.
•
Open the shielding box access door (open the INTLK terminal).
•
Discharge any capacitors if the capacitance is connected to an SMU.
•
Warn workers in the vicinity of the Agilent 4155C/4156C/41501B about
dangerous conditions.
