ADJUSTMENT
f. Verify that the table below is satisfied when the tests are made by changing DUT and
CIRCUIT MODE (as given in table):
16362A C%l%g%?T Capacitance |Dissipation Factor
LCR RANGE MODE Readout Readout
PRL
1000pF D=0.01 -I__:,:l— *C. V. £ 2 counts | *C. V. + 2 counts
PRL
1000pF D=1.8 -{j:_l— Approx. 1100 counts| *C. V. £ 3 counts

B «C V. = Calibrated Value of DUT.
g. If table test fails, repeat step e.
(2) A12C1 Adjustment.
Note
The follawing A12C1 Adjustment needs to be
performed only when A12R4 is replaced.
a. ‘Set 16362A LCR RANGE to 100nF D = 1.8 or connect the following sample, as an
alternate DUT, to 16061A.
C
m C: 100nF (HP P/N: 0160-4113)
R R: 100©2 (HP P/N: 0698-6323)
b. Verify that the dissipation factor readout on 4262A DQ display is the calibrated value
of the DUT within a tolerance of + 3 counts. If not within tolerance, change A12C1 to
an appropriate value selected from the adjustment range below:
6800pF HP P/N: 0160-0159
8200pF - HP P/N: 0160-0160
10000pF HP P/N: 0160-0161
Note
Nominal value is 6800pF. Increasing A12C1
by 1000pF increases display 2 counts.
(3) A12C3 Adjustment.
a. Remove Test Leads and attach 16061A Test Fixture to 4262A UNKNOWN terminals.
b. Connect the following DUT to 16061A.
