To measure gate trigger voltage and current, raise gate
the relationship
I = I - ____ Amps
where I
dropping
Note: I may turn out to be a negative quantity (trigger
current flows out from gate lead). If negative current
occurs, I value is not a valid reading. Remove 1 k resistor
and use I as the more correct I value. This will occur on
12 μA gate products.
