To Install LED Circuit
The 4155/4156 semiconductor parameter analyzer's Intlk connector provides the
interlock signal and a LED drive signal.
If a LED is connected between pin 4 and pin 5 (or 6) of the interlock connector, the
LED lights to indicate high voltage output when more than ±40 V is forced from an
SMU in the 4155/4156.
To install LED circuit on your shielding box, do following:
1. Mount LED on your shielding box. For the dimensions of the LED, refer to
Figure 4-5.
2. Use wire to connect the LED between pin 4 and pin 5 (or 6) of the interlock
connector. Refer to Figure 4-2.
