(Confirmation check)
Note
If 16362A DUT Box is available, use pro-

PROCEDURE A.
g. Remove 16061A from 4262A UNKNOWN terminals and connect Test Leads (HP
P/N: 16361-61605) between 4262A UNKNOWN terminals and 16362A DUT Box as
shown in Figure 5-12 (a).
h. Set 16362A LCR RANGE to 1pF position.
i. Set4262A CIRCUIT MODE to PRL.
j. Adjust C ZERO ADJ potentiometer for calibrated value of 16362A0n 4262A LCR
display.
k. Set 16362A LCR RANGE to 100pF D =1.8.
