*1 KW2G can measure regeneration electric power.
Integrated electrical power is not integrated (not subtracted) when detecting regeneration power.
*2 While detecting regeneration electric power, minus is displayed on instantaneous active power and
power factor.
*3 It determines pulse or minus of instantaneous reactive power by the input measuring voltage and the
input measuring current.
When harmonics or a wave pattern is warped, it may not determine correctly.
*4 Eco-POWER METER is designed chiefly to manage saving energy.
It is neither intended nor can it be legally used for billing.
*5 Frequency and pulse counter are only for main unit.
*6 Expansion unit (Analog input) doesn’t have the hour meter function.
With expansion unit (Pulse input), maintenance time and actual work time can be measured.
Maintenance time by using pulse input can’t be measured with expansion unit (Power measurement)
and expansion unit (Power measu Pulse outout).
For ratio of ON-time1 and ratio of ON-time2, it uses measuring value inside every 1 sec., therefore it
may be different when you compare with OFF-time, ON-time1, ON-time2, maintenace time and
actual work time.
Hour meter function can be used only with main unit and one expansion unit.
*7 Displayed digit of pulse counter differs according to the pre-scale set by pre-scale setting mode.
