Installation

• Do not install the instrument with any side except the bottom facing down.

• Do not install the product on an unstable or un level surface

To prevent electric shocks and personal injury, do not directly touch the exposed metallic parts of the input terminals and other wiring materials when the measurement lines connected to the input terminals at the rear panel of the instrument are live lines. In addition, do not allow them to touch or come near metallic parts.

lTo meet the measurement accuracy, ensure the surrounding temperature of the instrument does not exceed

23±5°C

by keeping it away from heat sources.

Handling the Instrument

To avoid electric shock, do not remove the instrument's case. The internal components of the instrument carry high voltages and may become very hot during operation.

• Do not allow the instrument to get wet, and do not take measurements

with wet hands. This may cause an electric shock.

• Never modify the instrument. Only Hioki service engineers should disas-

semble or repair the instrument. Failure to observe these precautions may result in fire, electric shock, or injury.

To avoid damage to the instrument, protect it from physical shock when transporting and handling. Be especially careful to avoid physical shock from dropping.

Operating Precautions

Handling the cables

Before Connecting

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 interfe rence to the reception of radio and television broadcasts.

• Avoid stepping on or pinching cables, which could damage the cable insulation.

• To avoid breaking the cables, do not bend or pull them.

• To avoid damaging the power cord, grasp the plug, not the cord, when unplugging it from the power outlet.

• Keep the cables well away from heat sources, as bare conductors could be exposed if the insulation melts.

• Before turning the instrument on, make sure the supply voltage matches

that indicated on the its power connector. Connection to an improper supply voltage may damage the ins trument an d present an e lectrical h azard.

• To avoid electrical accidents and to maintain the safety specifications of this instrument, connect the power cord provided only to a 3-contact (two-conductor + ground) outlet.

See Connection procedure:"2.3 Connecting the Power Cord"( p.21)

Operating Precautions

Input and Measurement Precautions

• The maximum input voltage and current is 300 V, 30 A. Attempting to

measure voltage and current in excess of the maximum input could destroy the instrument and result in personal injury or death.

• The maximum rated voltage between input terminals and gr ound is 300 V.

Attempting to measure voltages exceeding 300V w ith respect to ground could damage the instrument and result in personal injury.

• This product should only be connected to the secondary side of a

breaker, so the breaker can prevent an accident if a short circuit occurs. Connections should never be made to the primary side of a breaker, because unrestricted current flow could cause a serious accident if a short circuit occurs.

When connecting wires,

Observe the following to avoid electric shock and short circuits.

• Turn off the power to lines to be measured before making connections to

terminals to be measured and turning on the instrument.

• Be sure to connect the voltage input and current input terminals cor-

rectly. An incorrect connection could damage or short circuit this instrument.

• Make sure no connecting wires are routed so they short circuit input

voltage terminals.

When the instrument gives off smoke, a strange odor or makes a strange noise,

Stop measuring immediately. Then perform the following procedure. Continued use under these conditions could result in fire and electric shock.

1. Turn the instrument power switch off.

2. Disconnect the power cord from the wall outlet.

3. Turn off the line to be measured and remove any connections.

4. Contact your dealer (agent) or nearest sales office.

• For safety reasons, disconnect the power cord when the instrument is not used and before connecting it to a device to be tested.

• To avoid damage to the instrument, do not short circuit or apply an input voltage to output terminals.

• Correct measurement ma y be impossible in the presence of strong magnetic fields, such as near transformers and high-current conductors, or in the presence of strong electromagnetic fields such as near radio transmitters.

To ensure measurements are accurate,

• Warm up the instrument 3 minutes or more before use.

• Pay attention to heat dissipation to maintain accurate measurements. Example: Keep the instrument away from heat sources, make sure there is enough free space around the instrument and install a fan when the unit is mounted in a rack.

• The instrument should be calibrated once a year.

Regarding measurement values

• Apparent power (S) and power factor (



) displayed by this instrument are values calculated from measured voltage (U), current (I) and active power (P). For information on the calculation method used, refer to"5.2 Basic Specifications"( p.120).A measuring instrument using a different operating principle or a different calculation method may therefore prod uc e different value s.

• Voltage and current values that are less than 0.5%

of their measurement ranges, and peak voltage and

peak current values that are less than 0.3%

of their peak ranges, are suppressed (forced to display as

zero).

• Deviations may occur in the measurement of high-frequency common mode voltages

• This instrument is designed to handle DC and frequencies between 45 Hz to 5 kHz, and cannot measure frequencies outside this range.

• Measureable peak voltage and current values are for DC input and AC input between 45 Hz and 1 kHz. DC peak values and AC values at frequencies outside of the range 45 Hz to 1 kHz cannot be measured correctly.

• The displayed values of voltage and current measurements at different frequencies may be scattered.

2.1 Installation & Connection Procedures

Measurement

Prep arations Chapter 2

2.1 Installation & Connection Procedures

Be sure to read the "Operating Precautions" ( p.4) before installing and connecting this instrument.

2.2 Connecting a Connection Cable

Please read the following before making connections

• The maximum input voltage and current is 300 V, 30 A.

Attempting to measure voltage in excess of the maximum input could destroy the instrument and result in personal injury or death.

• The maximum rated voltage between input terminals and gr ound is 300V.

Attempting to measure voltages exceeding 300V w ith respect to ground could damage the instrument and result in personal injury.

• This instrument should only be connected to the secondary side of a

breaker So the breaker can prevent an accident if a short circuit occurs. Connections should never be made to the primary side of a breaker, because unrestricted current flow could cause a serious accident if a short circuit occurs.

• Confirm that no terminal is loose.

A connection that becomes disconnected could cause a short circuit or electrical shock. A loose connection will increase the insulation resistance resulting in heat generation, burn damages or fire. (Use a torque of 3Nm to secure the input terminals.)

Observe the following to avoid electric shock and short circuits.

• Turn off the power to lines to be measured before making connections to

terminals to be measured and before turning on the instrument

• Be sure to connect the voltage input and current input terminals cor-

rectly. An incorrect connection could damage or short circuit this instrument

• Make sure no connecting wires are routed so they short circuit input

voltage terminals

• Do not move cables around unnecessarily as terminals may become

loose.

Before turning on the power to the line to be measured

Turn on this instrument before turning on the power to the line to be measured. Confirm that no errors are indicated and then turn on the power to the line to be measured. Powering up the line to be measured before this instrument is turned on may damage the instrument or generate an error when it is powered up

See "2.4 Turning the Power On and Off"( p.21), "6.2 Error Indication"( p.127)

Power supply side

Load side

2.2 Connecting a Connection Cable

Using an external VT (PT) or CT device

Use an external VT (PT) or CT device to for measurements of a device under test whose voltage exceeds the measurement range of this device. By setting the VT or CT ratio, you can directly read primary side input values

See "3.2.5 Setting the VT or CT ratio"( p.32)

To prevent electrical shock and personnel injury, do not touch any input terminals on the VT (PT), CT or the instrument when they are in operation.

• Do not short circuit the secondary side when using an external VT (PT)

device Applying a voltage to the primary side when the secondary side is shortcircuited will result in the generation of a high current on the secondary side that could lead to burn damages and fire.

• Do not open the secondary side when using an external CT device.

Applying current to the primary side when open will generate high current in the secondary side and could pose serious danger

• Note that a phase difference in the external VT (PT) or CT device may cause substantial deviations in current measurements. Use a VT (PT) or CT device with a minimal phase difference in the frequency bandwidth to ensure accurate measurement results.

• For reasons of safety, connect the secondary side of a VT (PT) and CT device to ground. (See figure below.)

For other safety precautions, refer to "Operating Precautions" ( p.4)

For accurate measurements:

• Since polarity is an important factor in power measurements, make sure that voltage and current inputs are correctly connected. The instrument will not yield accurate measurement results when incorrectly connected.

• Make sure that power lines are routed away from the instrument as the external electromagnetic fields they produce could have a negative effect on operation.

Wiring material (for voltage and current input terminals)

To avoid electric shock and short-circuit accidents, use only solderless terminals whose wires are properly insulated. (Screws for voltage and current input connectors: M6)

To prevent electrical shock, make sure that the materials used ha ve sufficient withstand voltage and current capacity.

Make sure that the power to a line to be measured is turned off bef ore making connections.

Selecting connection method

Instrument loss in the wattmeter may affect the measurement value depending on the input level. Then use method 2 to minimize loss.

Example:

When measuring 100 V, 20 A

Method 1: loss = (100 [V]) Method 2: loss = (20 [A])

Method 1 involves less loss and provides a more accurate measurement.

When measuring 100 V, 50 mA

Method 1: loss = (100 [V]) Method 2: loss = (50 [mA])

Method 2 involves less loss and provides a more accurate measurement.

/2.4 [M] = 0.0042 [VA]

Press and then press , auto-range current measurement is enabled.

When auto-ranging is enabled, the AUTO RANGE LED is lit along with a measuring range LED.

3.2 Setup Procedure

3.2.2 Selecting Voltage and Current Range

When the input exceeds 300 V or 30 A, Maximum input voltage and maximum input current are 300 V and 30 A,

respectively. When the maximum input voltage or current is exceeded, terminate measurements as soon as possible, turn off the measurement line and disconnect all connections.

Continuing measurements while maximum input voltage and maximum input current are exceeded will damage the instrument and could lead to injuries.

Selecting a range

Press a range key.

The LED for the selected range key lights and measurement values for the selected range appear.

Wait (one second or more) until the internal circuit has stabilized after changing a range before reading measurements.

See "Effective measurement range and display range" ( p.27)

Note that the instrument may be damaged if the applied voltage or current exceeds the measurement range.

Selecting auto-range

Use auto-range when the range is not known.

See "Auto-range" ( p.28)

To cancel auto-range:

Press any range key, or press again and then press (volt-

age range) or (current range).

When the measurement range is set to auto-range, analog output or waveform output changes the output rate according to changes in range. In measuring a line whose measurement value fluctuates wildly, take care not to mistake the range conversion. It is recommended that a fixed range be used for such measurements.

3.3.3 Notes on Integration

1. Current integration effective measurement range : ±1% to ±100% of current range Active power integration effective measurement range: 0% to ±100% of active power range

2. When starting integration, auto range setting of voltage and current is canceled and the range at integration starting point is fixed. It is necessary to set the range so that PEAK OVER U (voltage over-range warning) LED and PEAK OVER I (current over-range warning) LED will not light during integration. When the PEAK OVER U or PEAK OVER I LED is lit while integrating, the integration value is invalid. In this case, the Ah or Wh unit flashes. This continues flashing until the integration value is reset (DATA RESET). (Even when the current or active power measurement value is out o f ra nge (" o.r”), integration is performed for the measurement values for which the PEAK OVER U or PEAK OVER I LED is not lit.)

3. The limitations of this instrument due to integration The following settings cannot be changed in the integration execution state (INTEGRATOR LED lights) or

Connecting to the ANALOG/WAVEFORM Output Terminal

Connect one wire to the terminal corresponding to the measurement value to be output. Connect the GND terminal of this instrument to the GND terminal of a data logger or recorder to which the data is to be output.

When the power to the line to be measured is turned on after connection, the voltage is also output to the output device.

To avoid damage to the instrument, do not short circuit or apply an input voltage to output terminals.

Usage example:

3.4 Analog Output and Waveform Output

3.4.1 Analog output

The ANALOG OUTPUT terminal can output measurement valu es as a level co nverted voltage. This output is isolated from voltage and current inputs. A data logger or recorder can use this data. Output items: following 4 items

• voltage

• current

• active power

• One of the following: current integration, active power integration, apparent power or po wer factor

Output resistance 100 ±5  (±5%) Response time 0.5 s or less Output update rate 200 ms

• When a VT or CT ratio is used, the range is multiplied by the VT ratio and CT ratio producing +2 V DC.

• When the measurement range is set to auto-range, the analog output changes the output rate according to changes in range. In measuring a line whose measurement value fluctuates wildly, take care not to mistake the range conversion. It is recommended that a fixed range be used for such measurements.

• The response time for the analog output of this instrument is 0.5 s.

• Note that a line that fluctuates faster than the output response time of the instrument will produce a deviation in the output voltage.

• The analog output outputs measured instantaneous values every 200 ms. Thus the analog output changes also in the display hold and during an averaging process.

(1) When the integrated value equals a multiple of "the measurement range

multiplied by the set integration time", the analog output of the integration value becomes ±2 V. For example, if the measurement range is 150 W and the integration time is set to 24 hours, when the integrated value is 3.6 kWh (150 W x 24 hours), 7.2 kWh (150 W x 24 hours x 2) , 10.8 kWh (150 W x 24 hours x 3)  its the analog output will be +2 V. When it is a multiple of -3.6 kWh, the analog output will be -2 V.

(2) When integration has started, analog output voltage begins to change.

(3) When analog output voltage exceeds ±2 V, analog output voltage returns to

When power to the line being measured, and disconnect all connections. When the LED lights at a lower value, the internal circuit is not operating correctly. Switch over to a range that does not light the PEAK OVER U LED.

• When the PEAK OVER I LED lights When

±54.0 A is exceeded, stop measuring as quickly as possible, turn off the

power to the line being measured, and disconnect all connections. When the LED lights at a lower value, the internal circuit is not operating correctly. Switch over to a range that does not light the PEAK OVER I LED.

See"3.2.2 Selecting Voltage and Current Range"( p.26)

±300% of any voltage range

±300% of any current range

3.6.2 When o.r (over-range) appears

This icon appears when a range is exceeded by 105%. (For information on ranges: refer to "Effective measurement range" ( p.121)) A calculation based on data that has generated an "o.r" will also produce an "o.r" display.

• When the voltage or current is "o.r", the apparent power, active power and power factor all become "o.r".

• When the apparent voltage is 0, the power factor becomes "o.r".

• However, a power factor that is "o.r" when apparent power is 0 will produce a normal value if the voltage and current inputs are made.

Remedy:

• When the voltage is "o.r", Switch to a range that is not over-range. When “o.r” is displayed with the 300-V range selected, stop measuring as quickly as possible, turn off the power to the line being measured, and disconnect all connections.

• When the current is "o.r", Switch to a range that is not over-range. When “o.r” is displayed with the 30-A range selected, stop measuring as quickly as possible, turn off the power to the line being measured, and disconnect all connections.

• "3.2.2 Selecting Voltage and Current Range"( p.26)

3.6.3 When the unit flashes

The unit may sometimes flash during an average operation. In some cases, the integration value unit indicator also flashes. This indicates that the displayed average value con ta ins "o.r" . Along with the integration value, PEAK OVER is indicated when this condition occurs during measurement.

When an over-range ("o.r") measurement occurs, averages are calculated using internal voltage and current data that exceeds 105% of their ranges, and active power and apparent power data that exceeds 110.25% of their ranges.

Remedy:

• The LED does not flash when "o.r" does not occur in the average period.

• It does not flash unless PEAK OVER occurred during integration.

• When the voltage flashes: Change the measurement range. If the 300-V range is already selected, stop measuring as quickly as possible, turn off the power to the line being measured, and disconnect all connections.

• When the current, active power or apparent power LED flashes: Switch to a range that does not cause flashing. If the 30-A range is already selected, stop measuring as quickly as possible, turn off the power to the line being measured, and disconnect all connections.

See "3.2.2 Selecting Voltage and Current Range"( p.26)

• When only the power factor flashes: This happens when the apparent power is 0 and is thought to be caused by load fluctuations. Flashing stops when the apparent power changes to something other than 0.

• When the integration value unit flashes: Reset the integration value, then change the range and restart integration.

Connect the RS-232C cable to the RS-232C connector.

To connect the instrument to a controller (DTE), use a crossover cable

compatible with

the connectors on both the instrument and the controller.

4.2 Connect a cable to the RS-232C connector or GP-IB connector

• Always turn both devices OFF when connecting and disconnecting an

interface connector. Otherwise, an electric shock accident may occur.

• To avoid damage to the product, do not short-circuit the terminal and do

not input voltage to the terminal.

• Connect this instrument to the RS-232C or GP-IB connector on the

device to be connected. A connection to a connector with different electrical specifications may result in an electric shock or equipment damage hazard.

• Use a common ground for both the instrument and the computer. Use of different ground circuits will result in a potential difference between the instrument's ground and the computer's grou nd. If the communications ca ble is connected while such a potential difference exists, it may result in equipment malfunction or failure.

• Before connecting or disconnecting any the communications cable, always turn off the instrument and the computer. Failure to do so could result in equipment malfunction or damage.

• After connecting the communications cable, tighten the screws on the connector securely. Failure to secure the connector could result in equipment malfunction or damage.

Remote state

Press the SHIFT(LOCAL) key.

The REMOTE LED goes out.

Various messages are supported for controlling the instrument through the interfaces. Messages can be either program messages, sent from the controller such as PC to the instrument, or response messages, sent from the instrument to the controller.

RS-232C also provides messages that confirm operations to ensure that controller and instrument processing are synchronized.

4.4 Communication Methods

Message types are further categorize d as follow s:

When issuing commands that contain data, make certain that the data is provided in the specified format.

During communications, REMOTE is lit to indicate the remote control state. Pressing the key except the SHIFT (LOCAL) key has no effect.

When the remote control state is invoked and the instrument is in the setting screen, the measurement screen is displayed automatically This key is disabled if the GP-IB controller has put the instrument into the local lock out state (LLO: mand of the interface function, or reboot the instrument. Then it returns to the local state.

4.4.1 Message Format

Program Messages

Response Messages

Program messages can be either Command Messages or Query Messages.

•

Command Messages

Instructions to control the instrument, such as to change settings or reset

Example: instruction to set the measurement range

:CURRENT:RANGE 0.1

• Query Messages

Requests for responses relating to results of operation or measurement, or the state of instrument settings.

Example:Command for inquiring current measurement range

:CURRENT:RANGE?

For details:

See

"Headers" (

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

:HEADer" command determines whether headers are prefixed to

response messages.

 p.63)

, "Separators" (

 p.64)

, "Data Formats" (

 p.64)

Confirmation Messages

Header ON Header OFF 0.1

At power-on, Header ON is selected. If an error occurs when a query message is received, no response message is generated for that query. There are also messages such as *TST? that do not have a header.

A confirmation message is created from three-digit numeric data (ASCII code) after analyzing and running 1 line of data (data up to the terminator) from the controller. This numeric data is returned to the controller. This data makes it possible to synchronize controller and instrument operations. ( p.102)

Example: Confirmation massages

000: Indicates the transferred command ended normally. 001: The command at the beginning (first) of the program message was not correctly

processed.

010: The 10th command in the program message was not correctly pr ocessed.

• When a confirmation message is specified, import it after sending the program message as the instrument will not otherwise properly synchronize with the controller. This message also works with GP-IB and must be received. Any query commands should be added at the end of a response message.

• A command that generates command errors, execution errors or device dependent errors is regarded as abnormal.

:CURRENT:RANGE 0.1

(the current range is 100 mA)

4.4 Communication Methods

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 uppercase letters, extended to the long form in lower case letters, although the commands are not case-sensitive in actual usage.

DISPLAY DISP DISPL DIS

Response messages generated by the instrument are in long form and in upper case letters.

OK (long form) OK (short form) Error Error

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

:ESE0 1

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

:CURRent:RANGe

• 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 "

*TST?

?" after a program header.

:CURRent:RANGe 0.1;:AVERaging 10

:CURRent:RANGe 0.1

:MEASure? V,A

:HOLD ON

4.4 Communication Methods

Message Terminators

Separators

This instrument recognizes the following message terminators:

•

• CR+LF

• EOI

• LF with EOI

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

• LF with EOI

• LF with CR and EOI (initial setting)

See "Set and query the response message terminator" ( p.107)

• LF

• CR+LF

• LF

• CR+LF (initial setting)

(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.

(2) Header Separator

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

(3) Data Separator

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

Data Formats The instrument uses character data and decim al numeric data, d epending on the

command.

(1) Character Data

Character data always begins with an alphabetic character, and subsequent characters may be either alphabetic or numeric. Character data is not case-sensitive, although response messages from the instrument are only upper case.

(2) Decimal Numeric Data

Three formats are used for numeric data, identified as NR1, NR2 and NR3. Numeric values may be signed or unsigned. Unsigned numeric values are handled as positive values.

:AVERAGING 10

This portion becomes the current path, and can be omitted from the messages immediately following.

4.4 Communication Methods

Values exceeding the precision handled by the instrument are rounded to the nearest valid digit.

• NR1 Integer data(e.g.: +12, -23, 34)

• NR2 Fixed-point data(e.g.:+1.23, -23.45, 3.456)

• NR3 Floating-point exponential representation data(e.g.:+1.0E-2, -2.3E+4)

The term "NRf format" includes all three of the above numeric decimal formats. The instrument accepts NRf format data.

The format of response data is specified for each co mmand, an d the da ta is sen t in that format.

The instrument does not fully support IEEE 488.2. As much as possible, please use the data formats shown in the Reference section. Also, be careful to avoid constructing single commands that could overflow the input buffer or output queue.

Compound Command Header Omission

When several commands having a common header are combined to form a compound command (e.g.,

:CURRent:RANGe and :CURRent:AUTO),

if they are written together in sequence, the common portion (here,

:CURRent:) can be omitted after its initial occurrence.

This common portion is called the "current path" (analogous to the path concept in controller file storage), and until it is cleared, the interpretation of subsequent commands presumes that they share the same common portion.

This usage of the current path is shown in the following example:

Full expression

:CURRent:RANGe 0.1;:CURRent:AUTO ON

Compacted expression

:CURRent:RANGe 0.1;AUTO ON

The current path is cleared when the power is turned on, when reset by key input, by a colon ":" at the start of a command, and when a message terminator is detected. Standard command messages can be executed regardless of the cur rent path. They have no effect upon the current path.

A colon ":" is not required at the start of the header of a Simple or Compound command. However, to avoid confusion with abbreviated forms and operating mistakes, we recommend always placing a colon at the start of a header. In this instrument, the current path is as follows

:CURRent:, :DATAout:, :INTEGrate:, :RS232c:, :SCALe:, :TRANsmit:, :VOLTage:

4.4 Communication Methods

4.4.2 Output Queue and Input Buffer

Output Queue Response messages are stored in the output queue until read by the controller.

The output queue is also cleared in the following circumstances:

• Power on

• Device clear

• Query Error

The output queue capacity of the instrument is 1000 bytes. If response messages overflow the buffer, a query er ror is generated and the output queue is cleared.

Also, with GP-IB, if a new message is received while data remains in the output queue, the output queue is cleared and a que ry error is generated .

Input Buffer The output queue capacity of the instrument is 500 bytes. When the input buffer

receives data that exceeds 500 bytes and becomes full, the GP-IB interface buss waits until buffer space becomes available. RS-232C does not receive data that exceeds 500 bytes. For example, if it receives 520 bytes from the controller, the 20 bytes from the 501st byte are not received.

Ensure that the no command ever exceeds 500 byte s.

Standard Event Register Description

Each of these bits corresponds to a specific event register

Overview of Service Request Occurrence

This instrument implements the status model defined by IEEE 488.2 with regard to the serial poll function using the service request line. The term "event" refers to any occurrence that generates a service request.

4.4 Communication Methods

The Status Byte Register contains information about the event registers and the output queue. Required items are selected from this information by masking with the Service Request Enable Register. When any bit selected by the mask is set, bit 6 (MSS; the Master Summary Status) of the Status Byte Register is also set, which generates an SRQ (Service Request) message and dispatches a service request.

SRQ (Service Request) is a GP-IB only function. However, STB (Status Byte Register) data uses the 232C can also access this information.

RS-232C does not provide a function for issuing service requests. Still, SRER setup and STB reading are available.

4.4 Communication Methods

Status Byte Register (STB)

During serial polling, the contents of the 8-bit Status Byte Register are sent from the instrument to the controller. When any Status Byte Register bit enabled by the Service Request Enable Register has switched from 0 to 1, the MSS bit becomes 1. Consequently, the SRQ bit is set to 1, and a service request is dispatched.

The SRQ bit is always synchronous with service requests, and is read and simultaneously cleared during serial polling. Although the MSS bit is only read by an

*STB? query, it is not cleared until a clear event is initiated by the *CLS com-

mand.

4.4.4 Event Registers

Standard Event Status Register (SESR)

The Standard Event Status Register is an 8-bit register. If any bit in the Standard Event Status Register is set to 1 (after masking by the Standard Event Status Enable Register), bit 5 (ESB) of the Status Byte Register is set to 1.

See "Standard Event Status Register (SESR) and Standard Event Status Enable Reg-

ister (SESER)" (

Command execution time indicates the time for analyzing and processing long form commands. However, the command execution time for commands with data is the time described according to the data format specified in the <data portion>, and for query commands it is the time when the header is ON.

• Due to internal processing, there may be a maximum time lag of 50 ms

between command reception and analysis in this instrument.

• When an analysis cannot be completed in the time allotted for internal pro-

cessing, data display is delayed.

• All commands are sequential commands.

• In communications with the controller, time must be added for data transmis-

sion.

• GP-IB transfer time depends on the controller.

The time for RS-232C transfers involving a total of 10 bits (the start bit is 1, data length is 8, no parity, stop bit is 1) is shown below. 9600 bps: approximately 960 characters/s

Error description (an error occurs when executing messages in the following cases):

*1 Command Error.................When data is present after the command

*2 Query Error........................When the response message exceeds 1000 bytes, or when a query follows *IDN?.

*3 Execution Error..................When invalid character or numeric data is present

*4 Device dependent Error.....When this command is executed at times other than in the hold state

*5 Device dependent Error.....When the self-test generates an error

NOTE:

• A misspelled message and the presence of data after a query always produce a command error.

• < > = contents of the data portion.

Numeric data values are indicated by format as (NR1), (NR2) a nd (NR3), representing integer, fixed-point and floating point decimal data values respectively, or as (NRf), representing any of these formats.

• In GP-IB, Event Status Enable Register and *SRE can be set to enable SRQ interrupts to the controller.

• When each query ends in some kind of error, no response message is created for the query.
