4276A and 4277A
1. Connect the attachment with the cover to the Guarded/Guard
electrode .
2. Press 4
ZERO OPEN
5 to start the OPEN Zero Oset A djustment. When
4
ZERO OPEN
5 is pressed, the instrument will be automatically set to
the C-G measurement mode . It will then measure the test xture's
stray admittance at each of the 9 preset frequency points . The
measured values are stored in the instrument's internal memory .
When oset adjustment is completed, DISPLA Y A and DISPLA Y
B will be blank for 1 or 2 seconds , after which the front panel
controls will be reset to the settings that existed when 4 ZERO OPEN 5
was pressed.
3. Remove the attachment from the electrode .
4. Connect the attachment without the cover to the Unguarded
electrode of the 16451B.
5. Press 4 ZERO SHORT 5 to start the SHORT Zero Oset A djustment.
When 4 ZERO SHORT 5 is pressed, the instrument will be automatically
set to the j Zj - (for the 4276A> or L-ESR (for the 4277A)
measurement mode . It will then measure the test xture's residual
impedance at each of the 9 preset frequency points . The measured
values are stored in the instrument's internal memory . When oset
adjustment is completed, DISPLA Y A and DISPLA Y B will be blank
for 1 or 2 seconds , after which the front panel controls will be
reset to the settings that existed when 4 ZERO SHORT 5 was pressed.
6. Remove the attachment from the electrodes and store it with the
cover in the carrying case .
