8. To measure R and X of a component (R range
.00001 Ω to 99999 kΩ, X range .0001 Ω to
9999 kΩ):
A. Press [SHIFT][R/X].
B. Place component in test fixture.
C. Press START.
The RLCGZY display shows R (series resistance) and
units (ohms, kohms); the QDRXB Angle display shows
X (series reactance) and units (ohms, kohms). {If
QDRXBAngle is negative, DUT is capacitive.}
9. To measure G and B of a component (G range
.00001 µS to 99999 S, B range .0001 µS to
9999 S):
A. Press [SHIFT][G/B].
B. Place component in test fixture .
C. Press START.
The RLCGZY display shows (parallel conductance)
and units ( µS, mS, S); the QDRXBAngle display shows
B (parallel susceptance) and units (µS, mS, S). {If
QDRXBAngle is negative , DUT is inductive.}
10. To measure Z and Angle of a component (Z
range .00001 ohms to 99999 kohms, Angle
range .0001 • to 180' ):
A. Press [SHIFT][Z/ANG].
B. Place component in test fixture
C. Press START.
The RLCGZY display shows Z (impedance) and units
(ohms, kohms); the QDRXBAngle display shows Angle
and units (degrees). {If QDRXBAngle is negative, DUT
is capacitive.}
11. To measure Y and Angle of a component (Y
range .00001 µS to 99999 S, Angle range
.0001° • to 180º):
A. Press [SHIFT][Y/ANG].
B. Place component in test fixture.
C. Press START.
The RLCGZY display shows Y (admittance) and units
(µS, mS, S); the QDRXBAngle display shows Angle and
units (degrees). {If QDRXBAngle is negative, DUT is
inductive.}
NOTE: This procedure is basic; there are many alter-
natives described later. You can select and program for
other equivalent circuits, types of results displayed,
test conditions, measurement rate, and bin sorting, etc.

3.2 Connecting the DUT

3.2.1 Overview

DANGER
C h a r g e d c a p a c i t o r s c a n b e
dangerous, even lethal. Never handle
their terminals if they have been
charged to more than 60 V. Routine
discharging procedures may not be
perfectly dependable.
NOTE: Clean the leads of the DUT if they are notice-
ably Dirty, even though the test-fixture contacts will
usually bite through a film of wax to provide adequate
connections. 3-4
Connect the "device under test" (DUT), whose pa-
rameters are to be measured, as outlined in the next
sections.
3.2.2 The 1689-9600 Remote Test
Fixture (with 1689-9602 BNC
Cable)
Connection of the DUT at a remote test fixture nor-
mally requires:
• Remote Test Fixture 1689-9600, or equivalent
fixture or cable
• BNC Cable Assembly 1689-9602 - supplied
with 1693 Digibridge
