rm the reactive power value
is correct, if correct, select Yes to continue, if
not correct, select No, the meter will return to
the active power to recalculate or display the
message to inform the adjustment of voltage
wiring recommendations
4.1.3.4 Finally will show the results, if correct,

select Cancel to leave the function or execute
function again.
4.1.3.5 The auto wire change function has different conditions under

erent input phase modes as follows:
4.1.3.5.1 3P4W-3CT : VN must be correct and
θ
< ±59

4.1.3.5.2 3P4W-1CT :
θ
< ±59

4.1.3.5.3 3P3W-2CT : V2 must be correct and
θ
< ±59

4.1.3.5.4 3P3W-3CT : V2 must be correct and
θ
< ±59

4.1.3.5.5 1P3W : VN must be correct and
θ

4.2 MAX/MIN
This meter logs maximum and minimum value statistics for phase/line voltages, current,
active power, reactive power, apparent power, power factor, frequency, demand,
unbalance factor, THD as well as the time they occur. All data is stored in non-volatile
memory so that statistic information can be preserved even when meter is shut off. All
maximum and minimum data can be accessed via communication or from the meter front.
Statistics can be cleared via communication or from the meter front.
Note: The MAX/MIN value clear is not cleared to zero, it’s becomes the value at the
time of erasure and begins to record the maximum and minimum value from the time of
erasure.
