Restrictions of measured data

F/W version is displayed in five seconds after the power loading to this device.
Measurement and communication do not performed in a few seconds after the configuration or the change of the rating to it.
Behaviors during operation are as follows:
Measured item
Current Indicate "0A" if RMS value is under 0.4% range of rating.
Indicate upper indication limit value if RMS value is over it.
Current demand Indicate upper indication limit value if RMS value is over it.
Voltage (*1) Indicate "0V" if RMS value is under 11V.
Indicate upper indication limit value if RMS value is over it.
Power Indicate "0W", "0var" or "0VA" if indicated voltage values of all phases
Power demand are 0V or indicated current values of them are 0A.
Reactive power Indicate upper indication limit value if the measured value is over it.
Apparent power
Power factor Indicate "100.0%" if indicated voltage values of all phases are 0V or
indicated current values of them are 0A
Frequency Voltage condition:
Indicate "----" if voltage V12 (voltage V1N for 3P4W) is 0V.
Frequency condition:
Indicate "----" if frequency is under 44.5Hz.
RMS value of Voltage condition:
harmonic current Indicate "----" at all phase if voltage V12 (voltage V1N for 3P4W) is
under 11V.
Indicate "0A" at all phase if voltage V12 (voltage V1N for 3P4W) is
under 40V.
Frequency condition:
Indicate "----" at all phases if frequency is under 44.5Hz.
Content rate of Voltage condition:
harmonic current Indicate "----" at all phase if voltage V12 (voltage V1N for 3P4W) is
(modulation under 11V.
distortion) Indicate "0.0%" at all phase if voltage V12 (voltage V1N for 3P4W) is
under 40V.
Frequency condition:
Indicate "----" at all phases if frequency is under 44.5Hz.
RMS value of Voltage condition:
harmonic voltage Indicate "----" at all phase if voltage V12 (voltage V1N for 3P4W) is
under 11V.
Indicate "0V" at all phase if voltage V12 (voltage V1N for 3P4W) is
under 40V.
Frequency condition:
Indicate "----" at all phases if frequency is under 44.5Hz.
Content rate of Voltage condition:
harmonic voltage Indicate "----" at all phase if voltage V12 (voltage V1N for 3P4W) is
(modulation under 11V.
distortion) Indicate "0.0%" at all phase if voltage V12 (voltage V1N for 3P4W) is
under 40V.
Frequency condition:
Indicate "----" at all phases if frequency is under 44.5Hz.
Pulse count When use of upper / lower limit alarm = oFF or upper / lower limit alarm
element ≠ pulse count (upper limit), counting restarts from 0 when
999999 have been exceeded.
When use of upper / lower limit alarm = on and upper / lower limit alarm
element = pulse count (upper limit), it is fixed to 999999 when 999999
have been exceeded.
Operating time (*2) Indicate "999999h" if operating time is over 999999h.
Periodic electric For contact input ON/OFF, integrated value may deviate up to 250 ms
energy less in time at the start or stop of integration.
*1: In single-phase, three-wire system, indicate "0V" if RMS value is under 22V.
*2: Operation time is reference value.
