■Precautions on preparation before use

⚫ Observe the use conditions and environment requirements for installation place. ⚫ You must set up the instrument before use. Read the manual carefully to set it up correctly. If the setup is

incorrectly done, the instrument will not be properly operated.

⚫ Check the power rating of the instrument and then apply proper voltage.

■Precautions on how to use ⚫ When operating the instrument, check that active bare wires do not exist around it. If any bare wire existed,

stop the operation immediately and then take appropriate action such as insulation protection.

⚫ If a power outage occurred during the setup, the instrument would not be set up correctly. Set it up again

after power recovery.

CAUTION

⚫ Do not disassemble or modify the instrument to use. Otherwise, a failure, an electric

shock, or a fire can be caused.

⚫ Use the instrument within the rating specified in the manual. If you used it outside the

rating, it might cause not only a malfunction or failure of the instrument but also ignition or burnout.

⚫ Do not open the CT secondary side while the primary current is energized. When the CT

secondary side circuit is open, the primary current flows. However, the secondary current does not flow. Therefore, a high voltage is generated at the CT secondary side and the temperature rises, resulting in insulation breakdown in the CT secondary winding. It may lead to burnout.

⚫ When external equipment is connected to the external terminals, the instrument and

external equipment must not be powered and be used after the definitive assembly on a cabinet door.

⚫ The rating of the terminal of external equipment should satisfy that of the external

terminal of the instrument.

2. Each Mode Function

The instrument has the following operation modes. When auxiliary power is supplied, the operating mode is first displayed. Depending on the application, switch the operation mode to use.

Mode

Description

Reference

Operating mode

This is a normal operation mode to display each measured value in digital

numerical number. In the operating mode, there are ‘Present value display’ that shows values at present and ‘Max/Min value display’ that shows the

maximum and minimum values in the past. In addition, on each display screen, the cyclic display mode, which automatically switches the display screen every 5 seconds, is available.

5 Operation

Setting mode

This is a mode where you can change the settings for measurement and output functions. In addition, on the CANCEL screen, which is the screen to cancel the setting change, the following special operations are available.

・ Restart the instrument. ・ Reset the settings to the factory default.

3 How to Set up

Setting confirmation mode (Test mode)

This is a mode where you can confirm the setting of each item. In this mode, you cannot change the setting. Therefore, it is possible to prevent from accidentally changing the setting. The mode also provides test function available at startup of systems. ・ Communication Test: Without measurement (voltage/current) input, fixed

numerical data is returned.

・ Analog output adjustment: Analog output adjustment is executed such as

zero adjustment or span adjustment.

・ Output test: Without measurement (voltage/current) input, alarm/digital

output, analog output, or pulse output is executed.

・ Support function for checking input wiring: ・ When either a voltage input or current input is incorrectly wired, the

incorrect wiring part is displayed on the screen. In addition, useful information is also displayed such as a current phase angle and voltage phase angle.

4. How to Use Test Mode

The test mode has function useful for startup of equipment. The following table shows a list of functions in the test mode.

Test menu

Description

1. Communication test

For models with communication function, without measurement (voltage/current) input, it is possible to return fixed numerical data. Use this for checking with the host system.

2. Alarm output/ Digital output test

For models with alarm/digital output function, without measurement

(voltage/current) input, it is possible to check alarm output (digital output) operation. Use the check of connection with the destination.

3. Zero/Span adjustment for analog output

For the model with analog output function, zero/span adjustment is possible for analog output. Use it for adjustment to the receiver side or output change.

4. Analog output test

For the model with analog output function, without measurement (voltage/current)

input, it is possible to check analog output operation. Use the check for connection with the receiver side.

5. Pulse output test

For the model with pulse output function, without measurement (voltage/current)

input, it is possible to check pulse output operation. Use the check for connection with the receiver side.

6. Functions for determining incorrect wiring

①Pattern display for incorrect wiring When either a voltage input or current input is incorrectly wired, this function

automatically determines incorrect wiring and displays its part on the screen. It is

easier to find out the incorrect part and useful to check the connection. *Note ②Support display for determining incorrect wiring This function displays a current phase angle, a voltage phase angle, and active

power, voltage, and current value of each phase. By checking each display and

9.3 A List of Examples for Incorrect Wiring Display, it is easier to determine

incorrect wiring of measurement (voltage/current) input.

*Note: The function cannot determine all incorrect wiring. If both a voltage input and current input are incorrectly wired, a different

pattern may be displayed.

■Test procedure

① Press for 2 seconds to enter the setting confirmation mode. ② With or , select ‘9’ in the setting confirmation menu number ③ Press to enter the test mode. ④ Execute the test in each test menu.

■Test mode flow

Note

1. When ME-0000BU-SS96 or ME-0000BU25-SS96 is activated, entering the test mode causes the power outage of

ME-0000BU-SS96 or ME-0000BU25-SS96 so as not to log the test data. As a result, the system log is recorded for power outage and COM of the LED blinks.

2. Entering from the test mode to the operating mode restarts this instrument. Therefore, if the built-in logging function is

activated, the system log for startup will be recorded. In addition, the present time setting is required again.

Note3: Periodic active energy can be separately reset to zero. Refer to 5.2.6.

5.1.11. How to Measure Reactive Energy (2 quadrant/4 quadrant measurement）

For measurement of reactive energy, there are two types on how to take a quadrant as follows. The measurement method of reactive energy can be switched at the active/reactive energy measurement settings in the setting menu 3. In addition, when you set to IEC mode in the setting menu 8, 2 quadrant measurement is executed even if you set to ‘Combination Ⅲ’ or ‘Combination Ⅳ’, which executes 4 quadrant measurement, at the active/reactive energy measurement settings.

When you select 4 quadrant measurement and IEC mode at each setting, ‘Imported lag’ and ‘Exported lead’ of reactive energy are displayed on the additional screen. However, they are not integrated. For details on how to switch the 2 quadrant/4 quadrant measurement, refer to 3.6. For details on how to switch the IEC mode setting, refer to 3.13.

Measurement

method

Description

4 quadrant measurement

Each of four quadrants (Imported lag, Imported lead, Exported lag, and Exported lead) is measured as one division. It is suitable to measure systems with a private power generator. However, a dead region occurs at the boundary of each division. Accordingly, reactive energy cannot be measured at where power factor is near 1 or zero.

2 quadrant measurement

‘Imported lag’ and ‘Exported lead’ are measured as one division, and in the same way, ‘Imported lead’ and ‘Exported lag’ are measured as one division. Therefore, a dead

region does not occur at where power factor is near zero and reactive energy can be measured even there. It is suitable to measure systems without a private power generator and reactive energy of capacitor load where power factor is zero generally.

5.1.13. Demand Time Period and Demand Value of Current demand

The demand time period (t0) represents a time period until a measured value (I0) displays 95% of the input (I) when continuously energized by constant input (I). To display 100% of the input (I), approximately three times the time period (to) is required.

The demand value represents a measured display value with the above feature on time period and it indicates the overall average value within the demand time period. The demand value changes over a relatively long time period. Therefore, it is not affected by input change for a short time. Accordingly, it is suitable to monitor overload of transformer.

Troubleshooting

If you observe abnormal sound, odor, smoke, or heat generation from the instrument, turn off the power at once. In addition, if you are considering sending the instrument in for repair, check the following points before it.

Situation

Possible cause

Solution

Display

The display does not light up.

Auxiliary power is not applied to MA and MB terminals.

Apply auxiliary power supply.

When the auxiliary power is applied, the display does not light up for a short time.

This is not an error. For a few seconds after charging the auxiliary power, the internal circuit is being initialized.

Use it as it is.

The backlight does not light up.

The backlight may be set to auto off (Auto). *When it lights up by pressing any

operation button, it is set to auto off.

When it is set to auto off, it automatically goes off in 5 minutes. Use it as it is or change the setting to ON (Hold). For details, refer to 3.7.

The display becomes black.

It may become black due to static electricity.

It will go off after a while.

The ‘End’ display remains.

It is in the setting mode.

Press the SET button.

Measurement error

The current and voltage errors are large.

The settings for VT/Direct voltage and CT primary current may be incorrect.

Check the settings for VT/Direct voltage and CT primary current.

The current and voltage are correct, but the active power and power factor errors are large.

The wiring for VT/CT and this instrument may be incorrect.

Check the wiring for VT/CT and this instrument.

The power factor error is large.

If input current is smaller than the rating, the error will become large. (approximately 5% or less of the rated current)

This is not an error. Use it as it is, or if the error is troublesome, change the CT according to the actual current.

The displayed active power is different from that calculated by multiplying the displayed current, voltage, and power factor.

If the current and voltage AC waveforms distort due to harmonics, the value will not be the same as the calculated value. (For current waveforms without harmonics, the calculated value matches with the displayed value.)

Use the instrument as it is. The total RMS value of

harmonic current is quite different from the current value.

The distortion ratio (content rate) is well over 100%. (For measurement of inverter secondary side output)

Check the measured item.

The current value measured by this instrument is different from that measured by other measuring instrument, such as a clamp meter. The difference exceeds an acceptable level.

If the comparative measuring instrument uses the average value method, the AC waveform will distort due to harmonics and the error of the comparative instrument will become large. (This instrument uses the RMS value method.)

Compare with a current value of a measuring instrument that uses the RMS value method.

The analog output error is large.

When the wiring with the receiver side is long, the error may become large.

Execute zero/span adjustment for analog output. Refer to 4.3Test

Menu 3: Zero/Span Adjustment for Analog Output.

The pulse output error is large.

When the pulse width is set to 0.500 s or

1.000 s, if the pulse unit is set to the minimum value, the pulse output cannot track under large load conditions and it can result in a decrease in the pulse output number.

Review the settings for pulse unit and width.

On the Max/Min value screen, a present value is displayed beyond the range of maximum and

minimum values.

During the starting current delay time, the maximum value is not updated. Therefore, the displayed present value may exceed the maximum value.

Use the instrument as it is.
