4. Taking measurements
a. Select measurement conditions as follows:
• [FUNCTION] key selects MEASURE mode
• [DISPLAY] key selects VALUE, ∆%, or BIN NO
• [MEASURE RATE] key selects SLOW, MEDIUM, or FAST
• [MEASURE MODE] key selects CONTINUOUS or TRIGGERED
• [EQUIVALENT CIRCUIT] key selects SERIES or PARALLEL
b. Select impedance to be measured as follows
• [R/Q] key to show Resistance in the primary display and Quality
factor in the secondary display
• [L/Q] key to show Inductance in the primary display and Quality
factor in the secondary display
• [C/D] key to show Capacitance in the primary display and Dis-
sipation in the secondary display
• [C/R] key to show Capacitance in the primary display and Resis-
tance in the secondary display
• To select other parameters, press and hold [SHIFT] key and
select as appropriate
The following programmable functions are available:
Parameter

Test voltage
Averaging
Delay
Internal Bias

5. Setting limits for GO/NO GO testing and sorting into bins
a. Make sure the appropriate VALUE is selected by pressing [DISPLAY] key as necessary.
b. Make sure to select ENTER by pressing the [FUNCTION] key.
c. Select the desired range and multipliers.
d. Select bins and limits as follows:
Option
Limit of 85
QDRXBΘ limits (always
bin 0)
Nominal value of 123.4
Symmetrical percentage
tolerances for RLCGZY
with ±0.2% limits in bin 1
(nested bins)
Nominal value of
Multiple tolerances (bucket
14.75 Ω
sort)*
with ±0.5 Ω limits in bin 2
+20%/-80% limits for
bin 6
Asymmetrical tolerances
*Overlapping values will always get assigned into the lower-numbered bin
e. Press [FUNCTION] key to select MEASURE mode.
f. Press [DISPLAY] key as needed to select the desired mode. (See Section 4 above.)
g. Connect component to be tested to the test terminals and press [START].
If the DUT falls into the limits of one of the active bins, the bin number will be displayed and the GO LED will be lit.
If the DUT falls outside the limits of the active bins, display with show bin 14 and the NO GO LED will be lit.

c. Connect component to be tested to the test terminals as
appropriate.
d. If in the TRIGGERED mode, press [START].
Keep hands and objects at least 10 cm (4 in) from test
fixture.
If NEG RLC lights, the selected parameter is not ap-
propriate for the DUT and another parameter should be
selected. For example, if the Digirbdige is set to measure
capacitance, and NEG RLC is lit, that means that the
DUT is inductive.
To view relative measurements, the nominal value and the bin
limits must be first programmed. (See section 5 below.) Once
the values have been programmed, select one of the following
options by pressing the [DISPLAY] key:
• % difference from the nominal value: ∆% must be lit
• Difference from nominal in original units (pF, mH, etc.): VALUE
and ∆% must both be lit
• Assigned bin number: BIN NO must be lit
