Dear all,
I found the instructions of step 3 of 177 calibration very confusing.
my doubts, up to this moment are:
1- in step 3e I should note the DMM reading, but I change the spot position to the 8th division only in step 3f.
2- What does the 4th column in table 5-1 mean by "within +-3%,+- 1nA"

I can't start the calibration procedure until I figure out this.
Please help!!!
