Precautions for measurement



Do not input voltage between the channels that exceeds the maximum

input voltage of the measurement modules, the maximum rated line-toground voltage, the maximum rated voltage between channels, or the

maximum rated voltage between modules.

• Maximum input voltage: Between the + and − inputs

• Maximum voltage between the channels: Between any channels of the same

module

• Maximum rated line-to-ground voltage: Between ground potential and the

input terminals

• Maximum rated voltage between the modules: Between channels of di󰀨erent

modules

Doing so could result in serious bodily injury or damage to the instrument. These rated voltages vary depending on the measurement modules. See

“13 Specications” (p. 355) for these values.

)

If you use modules with di󰀨ering maximum rated voltages between modules for a measurement target connected in series, such as a battery pack, the specications of

the module with the lower maximum rated voltage between modules will apply.

Example: Mixing the M7100, M7103, and M7102 to measure a battery pack

This combination cannot be used to measure a battery pack over 600 V, because the maximum input voltage between the modules is limited to 600 V DC.

Supplementary explanation about maximum voltage between the channels

When the maximum voltage between the channels is 300 V, make sure that the potential

di󰀨erence between the adjacent channels, as well as among all the channels, is within 300 V. For example, the potential di󰀨erence should be within 300 V between CH1 and CH2, and also between CH1 and CH15.

Usage Notes

HIOKI LR8102A961-02

DANGER



Do not touch any input terminals on the VT (PT), CT, or instrument when

they are in operation.

Doing so could result in serious bodily injury.



Do not use the instrument to measure circuits that exceed the ratings or

specications of the instrument.

Doing so could cause damage to the instrument or overheating, resulting in serious bodily injury.



Do not use the instrument and measurement modules to measure a main power supply circuit.

The voltages to earth of the M7100 and M7102 measurement modules are compatible with CAT II. However, these modules cannot be used for a measurement in CAT II, CAT III, or CAT IV. Never input a voltage in CAT II, CAT III, or CAT IV between the measurement terminals. Failure to do so could cause the operator to experience an electric shock or damage the instrument.



Do not short-circuit the two wires of the measurement line using the metallic tips of the sensors.

Doing so can cause arc ash, resulting in serious bodily injury or damage to the

device or other equipment.

WARNING



Do not allow the instrument to become wet.



Do not operate the instrument with wet hands.

Doing so could cause the operator to experience an electric shock.



Securely connect the measurement cables to the input terminals.

Loose terminals could result in increased contact resistance, causing the product to

become hot or burn up or resulting in bodily injury or re.



When no measurement module is connected, install the connector

cover.

Failure to do so could cause the operator to experience an electric shock or damage the instrument and measurement modules.

E󰀨ect of induced voltage

Due to induced voltage, the displayed value may become unstable when there is no input; however, this is not a malfunction.

A physical phenomenon called short range ordering occurs in K and T thermocouples. This

phenomenon may prevent accurate measurement between 250°C and 600°C.

Select the sensor while referring to the manufacturer of the thermocouples to be used.

The data always starts with an alphabetical character and consists of alphabetical and numerical characters. For the character data, both uppercase and lowercase letters are accepted. However, the response messages from the instrument are always returned with uppercase letters. As with the command syntax, the long and short forms are available and both are accepted.

Example:

:TRIGger:MODE SINGle

(2) Decimal numerical value data

For the numerical value data, the NR1, NR2, and NR3 formats are available. Each format can accept numerical values with and without a sign. Numerical values without a sign are treated as positive numerical values. In addition, if a numerical value is described to a decimal place that cannot be processed by the

instrument, the value is rounded o󰀨 to the next higher decimal place.

• NR1 integral number data (example: +12, −23, 34)

• NR2 decimal fraction data (example: +1.23, −23.45, 3.456)

• NR3 oating-point exponential notation data (example: +1.0E-2, −2.3E+4)

The format including all of the three formats above is referred to as the “NRf” format.

Page 25

The instrument can accept numerical values in the NRf format.

HIOKI LR8102A961-02

The response data are sent in the format specied for each command.

Abbreviation of combined command header

When the commands with a common leading part are combined, the repeated part can be omitted as long as the commands are described continuously. This common part is referred to as a “current path”. Until the current path is cleared, the subsequent commands are analyzed assuming that the current path is omitted.

An example of using the current path is shown below.

Normal notation

:SYSTem:COMMunicate:LAN:IPADdress 192,168,1,1;:SYSTem:COMMunicate: LAN:SMASk 255,255,255,0

Abbreviated notation

:SYSTem:COMMunicate:LAN:IPADdress 192,168,1,1;SMASk 255,255,255,0

This part denes a current path, which can be omitted in the subsequent commands.

The current path is cleared under the following situations.

• When the power is turned ON

• When a command starting with a colon (:) or an asterisk (*) is sent

• When a message terminator is detected

The single and combined command headers require no colon (:) at the beginning. However, it is recommended to place a colon (:) at the beginning of a command in order to prevent confusion with abbreviated forms and avoid malfunction.

Doing so could result in serious bodily injury.

WARNING



Do not short-circuit the secondary side when an externally installed VT (PT) is used.

Applying voltage to the primary side while it is short-circuited will cause a large current to ow into the secondary side, potentially resulting in burning or re.



Do not release the secondary side when an externally installed CT is used.

If current ows into the primary side while the secondary side is released, high

voltage will be generated on the secondary side, which could cause the user to

experience an electric shock.

IMPORTANT

The phase di󰀨erence for externally installed VT (PT) and CT may result in a signicant error during power measurement. To ensure more accurate power measurement, use the VT (PT) and CT that have less phase di󰀨erence in the frequency band of the circuit to be used.

This method uses two channels of the three-phase delta connection line to measure power using the two-wattmeter method. It accurately measures the active power of unbalanced and distorted waveforms. The apparent, reactive power, and power factor values of an unbalanced line may vary compared to other measuring instruments. In such a case, use 3V3A or 3P3W3M.

This method uses three channels of the three-phase delta connection line for measurement with the two-wattmeter method. It is preferred when compatibility with Hioki’s conventional power meters like the 3193 model is important.

It correctly measures not only the active power but also the apparent and reactive

power, and power factor, even on unbalanced lines.

This method uses three channels of the three-phase delta connection line to measure power using the three-wattmeter method. This method is suitable for measuring motor power in PWM inverter assessments, where high-frequency component leakage currents are signicant. It ensures accuracy even when using the 3V3A method, which might otherwise introduce errors.

This method involves using three channels of the three-phase Y (star) connection line to measure using the three-wattmeter method.

Current sensor phase compensation

In general, current sensor phase errors are more likely to increase gradually in the high-frequency area within the frequency band. It is possible to reduce power measurement errors in the highfrequency domain by correcting the measurement values using the phase characteristics information specic to the sensor.

Zero adjustment and degaussing (DMAG)

Before wiring, execute zero adjustment while no voltage and current are input. Zero adjustment is executed for all ranges of all input channels simultaneously. Also, when the current sensor available for AC/DC measurement is connected to the M7103 Power Measurement Module, degaussing (DMAG) of the current sensor is also executed at the same time.

When the power is ON, allow at least 30 minutes for the instrument to warm up.

Connect the current sensor and voltage cords to M7103.

When the current measurement value is corrected, the current sensor should be included.

When the current sensor connected to the instrument is available for zero adjustment,

perform zero adjustment on the current sensor side.

There are some current sensor models that allow you to perform zero adjustment using a knob.

Set the wiring mode and current sensor.

Execute zero adjustment.

The measured voltage value is too high.

The measured voltage value is too low.

The measured current value is not valid.

The active power measurement value is a negative value.

• The voltage cords are not securely inserted into the voltage input terminal on the instrument.

• The voltage cords are not connected properly.

• The current sensor is not securely inserted into the current input terminal on the instrument.

• The current sensor is not connected properly.

• The voltage cords are not connected properly.

• When wiring, the arrow that indicates the current ow direction of the current sensor does not point to the load side.

2.10 Setting and Connecting the LAN

The instrument and a PC can be connected using a LAN cable.

You can perform the following with LAN1

• Record and observe the settings of the instrument and the measurement data with Logger Utility. (p. 311)

• Remotely operate the instrument (setting, data acquisition, screen monitoring, etc.) using a standard browser, such as Microsoft Edge (HTTP server). (p. 313)

• Download les from the media (SD memory card and USB drive) to the PC (FTP server). (p. 324)

• Automatically send waveform data saved in the media of the instrument to the network or the FTP

server of the remote PC (FTP client). (p. 326)

• Control the instrument using communication commands. (p. 101)

• Control the instrument using XCP on Ethernet (TCP). (p. 339)

You can perform the following with LAN2 (LR8102 only)

• Output the measurement data based on the UDP. (p. 347)

• Control the instrument using XCP on Ethernet (UDP). (p. 339)

Connection (Preparation for Measurements)

IMPORTANT

Be sure to congure the LAN settings before connecting the instrument to the network. If you change the settings while the instrument is connected to a network, the instrument may have the same IP address as another device on the LAN, causing incorrect address information to be sent to the LAN.

HIOKI LR8102A961-02

Checking before connection

The settings are di󰀨erent when connecting the instrument to an existing network and when

connecting one instrument to one PC.

When connecting the instrument to an existing network

You must rst have the network system administrator (department) allocate the following parameters. Ensure that the instrument uses a unique IP address that is not being used by any other device on the network.

DHCP server DHCP server: Used/not used

Subnet mask The subnet mask is used to separate the IP address into the portion that

indicates the network and the portion that indicates the device. Ensure that the instrument uses the same subnet mask that is being used by other devices on the same network. If the DHCP server is enabled, the setting will be congured automatically using the server.

Gateway IP address

DNS

(Domain Name System)

• When connecting the instrument to a network When the PC to be used (communicating device) is on a di󰀨erent network than the network with which the instrument is connected, set this parameter to [ON] and specify the device that serves as the gateway. When the PC is on the same network, generally use the same setting as the default gateway setting of the PC.

• When connecting one instrument and one PC Set this parameter to [OFF] when they are connected to the same hub.

If the DHCP server is enabled, the setting will be obtained from the server.

If the DNS is enabled, the communication partner can be specied with its name instead of the IP address. (The IP addresses are di󰀩cult to remember because they are a series of numbers. It is easier if devices can be specied with their names instead of the IP addresses.) If a server that allows you to obtain the IP addresses using the names is operating on the network, the IP address of the communication partner can be looked up from the name by querying the server. If the DHCP server is enabled, the setting will be obtained from the server.
