3.1.4 Routine Measurement

1. Verify or select measurement conditions as
follows (indicated by keyboard lights); press
the adjacent key to change a selection.
• Function: MEASURE ([FUNCTION]
key), a necessary selection
• Display: VALUE ([DISPLAY] key), for
normal RLC/QDR results
• Measure rate: SLOW ([MEASURE
RATE] key). for best accuracy
• Measure mode: TRIGGERED
([MEASURE MODE] key), optional
• Equivalent circuit: SERIES
([EQUIVALENT CIRCUIT] key) - see
paragraph 3.3.
If you are in doubt about how to connect the device to
be tested with the Digibridge, refer to paragraph 3.2,
below.
2. To measure any passive component (without
knowing whether it is essentially a resistor,
inductor, or capacitor), use "automatic pa-
rameter selection".
This feature is provided at power-up and remains
enabled as long as you do NOT select any particular
parameter. (Automatic parameter selection can be
disabled by pressing the [C/D] key, for example. Once
disabled, this feature can be enabled again by selecting
the ENTER function and then pressing these keys:

3. Place DUT in test fixture. Press START. (See
note below.)
The RLC display and units indicator show the principal
measured value and the basic parameter, thus identifying
the DUT. The QDR display shows the measured Q if the
principal units are ohms or henries; the measured 0 if
they are farads.
4. To measure G and D of a Capacitor (C
Range .00001 pF to 99999 µF, 0 range .0001
to 9999):
A. Press [C/D].
B. Place capacitor in test fixture.
C. Press START.
The RLC display shows Cs (series capacitance) and
units (µF, nF, pF); the QDR display shows D (dissipation
factor). {If RLCGZY is negative, the DUT is inductive.}
5. To measure C and R of a Capacitor (C Range
.oooo1 nF to 99999 µF, R range .0001 ohm
to 9999 kilohm):
A. Press [C/R].
B. Place capacitor in test fixture.
C. Press START.
The RLC display shows Os (series capacitance) and
units (µF, nF); the QDR display shows Rs (equivalent
series resistance) and units (ohms, kilohms). {If
RLCGZY is negative, DUT is inductive.}
6. To measure L and Q of an Inductor (L range
.00001 mH to 99999 H, Q range .0001 to
9999):
A. Press [L/Q].
B. Place inductor in test fixture.
C. Press START.
The RLC display shows 15 (series inductance) and units
(mH, H); the QDR display shows Q (quality factor). {If
RLCGZY is negative, DUT is capacitive.}
7. To measure R and Q of a Resistor (R range
.00001 ohm to 99999 kilohms, Q range .0001
to 9999):
A. Press [R/Q].
B. Place resistor in test fixture,
C. Press START.
The RLC display shows Rs (series resistance) and units
(ohms, kilohms); the QDR display shows Q (quality
factor). {If QDRXBAng is negative, DUT is capacitive; if
not DUT is inductive.}
