2-1. Before using B1505A
There are potentially hazardous voltages (3000 V for HVSMU, and 200 V
for HPSMU) present at the Force, Sense, and Guard terminals of Agilent
B1505A. To prevent electrical shock, the following safety precautions
must be observed during the use of B1505A.
●
Use a three-conductor AC power cable to connect the cabinet (if
used) and B1505A to an electrical ground (safety ground).
●
You must connect an interlock cable between B1505A and the test
fixture.
●
Confirm periodically that the interlock function is functional.
●
Do not modify the interlock circuit.
●
Do not use extension cables for connecting the DUT the outside of
the test fixture.
●
Before touching the connections on the Force, Guard, and Sense ter-
minals, turn the B1505A off and discharge any capacitors. If you do
not wish to turn the B1505A off, complete all of the following items,
regardless of the B1505A settings.
- Press the Stop key to turn the module output off.
- Confirm that the High Voltage indicator is not lit.
- Open the shielding box access door.
- Discharge any capacitors connected to an SMU.
