3.7 Displaying Measurement Results

32

3.7.1 Measurement Fault Detection

If a measurement does not execute properly, a measurement fault
“- - - - -” is indicated on the display.
In addition, a measurement fault signal (ERR) is output at the EXT I/O
connector.



See Section 5.2.4 ERR Output (Page 73).

A measurement fault is displayed in the following cases.

• When a test lead is not connected to the test object

• When the resistance of the measured object is over-range
Example: Attempting to measure 30 Ω with the 300 mΩ range
selected.

• If any of the following is open, or has a bad connection: SOURCE­H, SOURCE-L, SENSE-H, SENSE-L

• When the resistance between SOURCE-H and SOURCE-L is 50 Ω
or more in the 300 mΩ range (or 500 Ω or more in the 3 Ω range)

• When the resistance between SENSE-H and SENSE-L is greater
than about 20 Ω. (However, if the capacitance of the test leads is 1
nF or higher, the measurement fault may not be detected.)

• When a bad contact results from damage, excessive wear or
impurities on the test leads.

• If the circuit protection fuse is blown



See Section 9.1 Troubleshooting (Page 163).

3.7.2 Overflow Display

Overflow is indicated by “OF” or “-OF” on the display, caused by one of
the following:

Display Condition

OF

• The measured value exceeds the limit of the current
measurement range

• When the result of relative value calculation is larger
than +99.999%.

-OF

• The measured value is below the limit of the current
measurement range

• When the result of relati ve value calculation is smaller
than -99.999%.

5.2 Signal Descriptions

72

0ADJ Zero adjustment executes once when the 0ADJ signal transitions from

High to Low.

PRINT The current measurement value prints when the PRINT signal

transitions from High to Low.

MANU When the MANU comparator mode is selected, comparator judgment

is enabled while the

MANU signal is Low.

See Section 4.1.4 Comparator Execution Mode Setting (Page 44).

IN0 to IN4 The TRIG, CAL, 0ADJ, PRINT and MANU signals can also serve as

general-purpose input terminals, read with the

:IO:IN? command.

See Section EXT I/O Input (Page 134).

5.2.3 Output Signals

ERR Indicates a measurement fault.

The Synchronous ERR output setting causes ERR output to be
synchronous with EOC output, while with the Asynchronous ERR
output setting causes ERR output to follow actual (asynchronous)
contact of the probes with the test obje ct.

See Section 5.2.4 ERR Output (Page 73).

INDEX The INDEX signal is output during the Trigger Wait, Delay, Self-

Calibration and Calculation stat es.
This signal is not output while measuring the resi stance of test object s.
This signal transitions from Off to On to indicate that the test object
can be removed.

EOC This signal indicates the end of a measurement (End-Of-Conversion).

This signal indicates when comparator judgment results and ERR
output (when SYNC is enabled) are available.

R-Hi, R-IN, R-Lo
V-Hi, V-IN, V-Lo

These are the results of comparator deci sion.

AND This signal indicates when both resistance and voltage judgment

results are IN (ΩV mode).
In the Ω and V modes, this signal is the same as R-IN and V-IN
outputs, respectiv e ly.

OUT0 to OUT9 The output signals are controlled by the :IO:OUT command.

See Section EXT I/O Output (Page 134).

INT.GND This is the instrument's internal ground.

• I/O signals should not be used while measurement settings have
been changed.

• The EOC and INDEX signals are initialized (ON) at power on.

• If it is not necessary to change the measurement conditions, set

LOAD0 through LOAD6 to either Hi or Lo.

: About t4 measurement time

When averaging is enabled, the running average is obtained with internal triggering, so
measurement time t4 does not change. The measurement time for external triggering is as
follows:
With SLOW sampling
ΩV (t4 - 57.8) X n + 57.8 ms (50 Hz)

(t4 - 51.2) X n + 51.2 ms (60 Hz)

Ω or V (t4 - 56.4) X n + 56.4 ms (50 Hz)

(t4 - 49.8) X n + 49.8 ms (60 Hz)

With other than SLOW sampling

ΩV (t4 - 2.8) X n + 2.8 ms
Ω or V (t4 - 1.4) X n + 1.4 ms

(n represents the number of values averaged)

*3

: About t5 calculation time

In the following cases, add the indicated times to calculation time t5:

When the Statistical Calculation function is enabled 0.3 ms
When the ref erence value/tolerance method of

comparator decision is selected

0.15 ms

7.4 Communication Methods

94

Message
Terminators

This instrument recognizes the following message terminators:

From the instrument's interface settings, the following can be selected
as the terminator for response messages.

See Section 7.3.2 Selecting the Interface (Page 91).

Separators

(1) Message Unit Separator

Multiple message can be written in one line by separating them with
semicolons ";".

• When messages are combined in this way and if one command
contains an error, all subsequent messages up to the next
terminator will be ignored.

• A query error occurs if a query command is combined with an
immediately following semicolon and subsequent command.

(2) Header Separator

In a message consisting of both a header and data, the header is
separated from the data by a space " ".

(3) Data Separator

In a message containing multiple data items, commas are required to
separate the data items from one another.

•LF

•CR+LF

•EOI

• LF with EOI

•CR

• CR+LF

• LF with EOI (initial setting)

• LF with CR and EOI

• CR + LF (initial setting)
