4 times/s
Approximately 0.5 s (time for displayed value to settle within accuracy specifications of final value
after step change from 0% to 100% or 100% to 0% of rated range)
Significant digits: Selected automatically according to significant digits in the voltage and current
ranges
Reassign ratio:0.001 to 9999
The following two algorithms can be selected:
Exponential averaging
Moving averaging
Response can be set; for exponential averaging, the attenuation constant can be selected and for
moving averaging, the number of averages (N) can be set to 8, 16, 32, or 64.
The alarm LED will light up when the RMS value is greater than 140% of the range or the peak
value is greater than 300% of the range.
Specification
Depending on elapsed time value, the resolution will be changed.
–99999 to 999999 MWh (or MAh)
Standard integration mode (timer mode)
Continuous integration mode (repeat mode)
Manual integration mode
When the timer is set, integration will be stopped automatically.
Setting range: 0 h:00 min:0 sec to 10000 h:00 min:00 sec (0 h:00 min:00 sec will be shown when
manual integration mode is selected automatically.)
If the integration count flows above 999999 MWh (or MAh) or below –99999 MWh (or MAh),
integration stops and the elapsed time is held on the display.
±(display accuracy + 0.2% of rdg) However, only when the input signal is continuous.
±0.02%
Start, stop, and reset can be remotely controlled by external contact signals.
However, the /DA4 option must be installed.
