Drain - Source
Operational Test
To prove the device is functional:
1. Connect the negative lead of the ohmmeter to the SOURCE lead.
2. Touch the ohmmeter positive lead to the gate, to pre-charge it.
3. Connect the ohmmeter positive lead to the DRAIN.
If the device is good you will get a resistance reading of about 400-1k ohms.
