3.10 Special Functions
Most of the special functions are described in more
detail in other parts of the manual. Refer to Table 3-12
for a brief summary of the special functions and how
to operate the [SPECIAL] key. Programming of spe-
cial functions can be done only in ENTER function.
Purpose
Autorange (normal)
Hold range 1
1. Setting the
Hold range 2
Range
Hold range 3
Hold range 4
No Output (max meas speed)
Bin numbers only
QDR results only
QDR and bin numbers
RLC results only
2. Output via IEEE-
488 Bus
RLS and bin numbers
RLC and QDR results
RLS, QDR and bin numbers = full data
No data on PASS, Full data on FAIL
BIN No. on PASS, full data on FAIL
Normal
Signal reversing (useful when test frequency coincides with power frequency)
3. Special
Shorting in measurement circuit (useful when measuring biased capacitors)
Measurement
Both reversing and shorting
Routines
Quick acquisition meas routine (MED and FAST only; useful at low frequencies)
Quick acquisition and shorting (MED and FAST only; useful at low frequencies)
4. Delay
Milliseconds of delay after start before data is qcquired, "d"=msec.
5. Integration Time
Multiplies integration time by factor f (0.25 to 6), normally 1. Reducing f decreases
Factor
accuracy and reduced measurement time. Increasing f does the converse.
Normal displays
Ratio Displayed:
6. Ratio Displays
(RLC only)
nominal/meas value
meas value/nominal
Manual selection of parameter
7. Man/auto
Parameter Section
Automatic selection of parameter (R/Q, L/Q, or C/D); default
Reset
Reset
Normal, no median found
8. Median Result
Display is median of 3 meas
9. Version
Displays the software version
10. Frequency
Displays the correction "c"
Correction
11. IEEE Address
Display the LISTEN address of the IEEE interface
