Operating Precautions

Preliminary Checks

Before using the instrument the first time, verify that it operates normally to ensure that the no damage occurred during storage or shipping. If you find any damage, contact your dealer or Hioki representative.

Before using the instrument, make sure that the insulation on the power cord and test leads is undamaged and that no bare conductors are improperly exposed. Using the instrument in such conditions could cause an electric shock, so contact your dealer or Hioki representative for replacements.

This instrument may cause interference if used in residential areas. Such use must be avoided unless the user takes special measures to reduce electromagnetic emissions to prevent interference to the reception of radio and television broadcasts.

Measurement Precautions

• To avoid electrical shock, be careful to avoid shorting live lines with the test leads.

• The maximum rated voltage between input terminals and ground is ing 60 V with respect to ground could damage the instrument and result in personal injury.

• To avoid injury or damage to the instrument, do not attempt to measure AC voltage and AC current, or DC voltage exceeding 22 V.

• To prevent an electric shock, do not exceed the lower of the ratings shown on the instrument and test leads.

± 60 V DC. Attempting to measure voltages exceed-

• Use only the specified test leads and cables. Using a non-specified

cable may result in incorrect measurements due to poor connection or other reasons.

• To ensure certified measurement accuracy, allow at least 30 min-

utes warm-up. After warm-up, be sure to execute self-calibration. See Section 4.9 Self-Calibration (P. 65).

• The input circuitry includes a protective fuse. Measurement is not possible when the fuse is blown.

• This instrument internally stores (backs up) all settings (except memory function and measurement values), such as measurement range, comparator settings and etc., but only when no operation is performed for a certain time. Therefore, to preserve settings, do not turn the power off for a short time (about five seconds) after changing a setting. However, measurement settings made through the RS-232C or GP-IB interface and measurement settings loaded

LOAD signals of the EXT I/O connector are not memorized.

1.1 Product Overview

HIOKI 3561A981-10

Overview Chapter 1

1.1 Product Overview

Overview

The Model 3561 and 3561-01 BATTERY HiTESTERs measure battery internal resistance using a four-terminal, 1-kHz AC method, while simultaneously measuring DC voltage (electromotive force [emf]). The high-precision, fast measurement performance and extensive interface capabilities make these models ideal for incorporating into battery testing production lines.

Page 16

HIOKI 3561A981-10

1.2 Features

Simultaneously Measures Battery Internal Resistance and Voltage

The four-terminal AC method measures resistance and DC voltage simultaneously, so battery internal resistance and emf are measured and judged at once.

High-Precision Measurements

The instrument provides high-resolution resistance (0.01 m) and voltage measurements (0.1 mV). High precision ( ensures accurate voltage measurements.

± 0.01% rdg.)

High-Speed Measurements

Simultaneous resistance and voltage measurements can be performed as fast as once every 10 ms.

Comparator Functions

Resistance and voltage measurement values are judged in three categories (Hi, IN and Lo), with results clearly displayed. A comparator judgment beeper also provides distinct sounds to indicate pass/fail judgments and to facilitate correct recognition of judgment results.

Statistical Calculation Functions

Maximum, minimum and average measurement values, standard deviation, process capability indices and other values can be automatically calculated for applications such as production management. Calculation results can also be applied as comparator setting values.

Measurement Value Memory Function

The instrument includes a Memory function and storage capacity for up to 400 pairs of measurement values. When making many sequential measurements at high speed and sending the measured values to a PC after each measurement, the time to switch test objects can become unsatisfactorily long. The Memory function can avoid the slow-down by sending stored measurements in batches during idle times.

EXT I/O Interface

EXT I/O and RS-232C interfaces are equipped as standard, supporting transfer rates up to 38,400 bps. Model 3561-01 also supports GP-IB.

Printing Measurement Values and Statistical Results

Connect the printer to print measurement values and statistical calculation results.

The sampling rate can be selected from EX.FAST, FAST, MEDIUM and SLOW. Slower sampling rates generally provide greater measurement precision.

Selects the sampling rate

EX.FAST FAST MEDIUM SLOW

• Measurements are especially susceptible to interference from the environment when EX.FAST is selected, so countermeasures such as shielding or twisting of test leads, cables and wiring around the test object may be necessary.

• When SLOW sampling is selected, self-calibration is executed during each measurement. At other sampling rates, self-calibration is executed manually or automatically every 30 minutes. See Section 4.9 Self-Calibration (p.65).

• Refer to the specifications for details of sampling rates. See Section Sampling Time (p.164).

3.6 Zero-Adjust Function

Execute zero adjustment before measuring to nullify any residual offset voltage from the instrument or measurement environment. Measurement accuracy specifications are applicable after zero adjustment. Zero adjustment can also be executed by the 0ADJ terminal of the EXT I/O connector. See Section 5.2 Signal Descriptions (p.72).

3.6.1 Wiring Method for Zero-Adjustment

Before executing zero adjustment, connect the test leads (probes) as follows:

1. Connect SENSE-H to SENSE-L.

2. Connect SOURCE-H to SOURCE-L.

3. Connect the joined SENSE and SOURCE leads together as shown

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 (p.75).

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  with the 300 m range selected.

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

H, SOURCE-L, SENSE-H, SENSE-L

• When the resistance between SOURCE-H and SOURCE-L is 50 

or more in the 300 m range (or 500  or more in the 3  range)

• When the resistance between SENSE-H and SENSE-L is greater

than about 20  (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 (p.169).

3.7.2 Overflow Display

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

4.1 Comparator Function

The comparator function compares measured values to preset upper and lower thresholds, judges the measurements according to their relative levels within the preset range, and indicates the results of the comparisons. Comparator thresholds can be set either by specifying upper and lower thresholds, or by specifying a reference value and tolerance. Comparator results can be indicated by the Hi, IN and Lo LEDs, beeper sound and signal output at the EXT I/O connector. See Section Chapter 5 External Control (p.71).

The comparator setting process flow is as follows:

Display the comparator settings

Set the comparator judgment beeper

4.1.8 Comparator Judgment Results

Resistance and voltage measurements are judged independently. Both judgment results are indicated on the display.

Judgment Operation The comparator compares measured values with the preset threshold

values, and judges whether the measurement is within the thresholds. Resistance and voltage measurements are judged independently. The absolute value of the measurement is compared to the upper and lower thresholds.

Upper Threshold Value < Measured Value

Lower Threshold Value 

Measured Value < Lower Threshold Value

Measured Value Upper Threshold Value

Applied Measurement

AND Judgment

Output

Measurement fault values are judged as follows:

Display Judgment

- - - - -

-OF

Judgment results (Hi, IN or Lo for both resistance and voltage) are output to EXT I/O connectors. Also, to facilitate application of judgment results, an AND output terminal indicates when both resistance and voltage are IN (within the threshold range). See Section 5.2.3 Output Signals (p.74).

With the relative value comparison method (thresholds defined by a reference value and tolerance), the upper and lower thresholds are calculated internally for comparison with measurements. Therefore, even if a relative display value is equal to a judgment threshold (tolerance limit), it may be judged Hi or Lo.

No judgment

Hi (exceeds the upper threshold)

Lo (less than the lower threshold)

4.5 Memory Function

The Memory function is only available via communication commands. When the Memory function is enabled, measurement values are stored in the instrument’s internal memory according to trigger input sequence (up to 400 values). Stored data can be downloaded later upon command. When measuring using a scanner to switch multiple test objects, switching time can be quite long if measurement values are downloaded to the PC after each measurement. Test cycle time can be minimized by using this function to store measurement values internally until all channel measurements are finished, at which time the stored values are downloaded together during the next idle period.

Select the RS-232C or GP-IB interface.

See Section 7.3.2 Selecting the Interface (p.91).

4.9 Self-Calibration

The self-calibration function adjusts offset voltage and gain drift of the instrument’s internal circuitry to improve measurement precision. The instrument’s measurement accuracy specifications depend on self-calibration, so it must be executed frequently. In particular, always execute self-calibration after warm-up and when the ambient temperature changes by more than 2 setting, self-calibration is executed during every measurement when SLOW sampling is used.

Self-calibration can be executed by the following two methods:

Auto Executes self-calibration automatically once every 30

To avoid electric shock or damage to the equipment, always observe the following precautions when connecting to EXT I/O connector.

• Always turn off the power to the instrument and to any devices to be connected before making connections.

• Be careful to avoid exceeding the ratings of EXT I/O connector.

• During operation, a wire becoming dislocated and contacting another conductive object can be serious hazard. Make sure that connections are secure the EXT I/O connectors.

• The INT.GND terminals (Page 73) are grounded, so if an external controller has a potential relative to ground, connection could cause a short-circuit accident.

Be aware of the following to avoid damaging the instrument:

• When using relays, always include diodes to absorb back emf.

• Always provide protective grounding for devices the connect to the EXT I/O connectors.

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 object. See Section 5.2.4 ERR Output p.75).

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

Calibration and Calculation states. This signal is not output while measuring the resistance of test objects. 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

These are the results of comparator decision.

V-Hi, V-IN, V-Lo

AND This signal indicates when both resistance and voltage judgment

results are IN (V mode). In the  and V modes, this signal is the same as R-IN and V-IN outputs, respectively.

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

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

See Section EXT I/O Output p.135).

• 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.

5.2.4 ERR Output

HIOKI 3561A981-10

The ERR output signal indicates the occurrence of measurement fault conditions (such as open test leads, or a bad contact). There are two ERR output methods.

5.2 Signal Descriptions

Synchronized with EOC Output (SYNC)

Asynchronous with EOC Output (ASYNC)

Measurement faults detected while measuring (not while awaiting trigger or during delay or calculation intervals), are indicated by ERR output synchronous with EOC output (the end-of-measurement signal). ERR Output On: A measurement fault has prevented correct

measurement

ERR Output Off: Correct measurement obtained (OF or -OF: Out-of-

range cases are included)

Measurement faults (test lead connection conditions) are output in real

time. The output is asynchronous with the output. ERR Output On: Measurement fault condition (open test leads, or a

bad contact)

ERR Output Off: Test lead connections are normal

Interval Printing _______________________________________________

This function allows you to automatically print out measurement results at preset intervals. The print interval time must be set from the Interface Selection display. See Section 6.2 Selecting the Interface (p.83). The setting range is 1 to 3600 seconds. When the print interval time is set to "0", interval printing is disabled, and only normal printing is carried out.

Operation when interval printing is selected:

1. Start printing by pressing the PRINT key or sending the

signal via EXT I/O.

2. Elapsed time (hours/minutes/seconds) and measurement values

are printed automatically at intervals corresponding to the preset interval time.

3. Stop printing by pressing the PRINT key or sending the

signal via EXT I/O again.

• When the printed elapsed time reaches 100 hours, it resets to 00:00:00 and continues from zero.

(Example) After 99 hours, 59 minutes and 50 seconds: 99:59:50 After 100 hours, 2 minutes and 30 seconds: 00:02:30

• Selecting a display other than the measurement display causes interval printing to stop.

Printing Statistical Calculation Results ____________________________

From the Statistical Calculation display, press the PRINT key to print statistical calculation results. If no valid data exists, only the data count is printed. When only one valid data sample exists, standard deviation of sample and process capability indices cannot be printed.

HIOKI 3561A981-10

Response Messages

When a query message is received, its syntax is checked and a response message is generated. The

:SYSTem:HEADer command determines whether headers are

prefixed to response messages.

Header ON :RESISTANCE:RANGE 300.00E-3 Header OFF 300.00E-3

(the current resistance measurement range is 300 m)

At power-on, Header OFF is selected. If an error occurs when a query message is received, no response message is generated for that query. No header is applied to commands used only for queries, such as

:FETCH? and :CALCulate:LIMit:RESistance:RESult?.

Command Syntax Command names are chosen to mnemonically represent their

function, and can be abbreviated. The full command name is called the "long form", and the abbreviated name is called the "short form". The command references in this manual indicate the short form in upper-case letters, extended to the long form in lower case letters, although the commands are not case-sensitive in actual usage. Response messages generated by the instrument are in long form and

Headers Headers must always be prefixed to program messages.

(1) Command Program Headers

There are three types of commands: Simple, Compound and Standard.

• Headers for Simple Commands This header type is a sequence of letters and digits

ESE 0

• Headers for Compound Commands These headers consist of multiple simple command type headers separated by colons ":"

:SAMPle:RATE

• Headers for Standard Commands This header type begins with an asterisk "*", indicating that it is a standard command defined by IEEE 488.2.

RST

(2) Query Program Header

These commands are used to interrogate the instrument about the results of operations, measured values and the current states of instrument settings. As shown by the following examples, a query is formed by appending a question mark "?" after a program header.
