Ɣ Demand measurement with this instrument
By measuring loads, the MODEL6300 can display the present and predicted
average power(demand value). These values are continuously updated as
time elapses during a particular interval.
The buzzer will sound and the backlight will flash when a predicted demand
value exceeds a target demand value after the elapse of the preset inspection
cycle.
The value which is displayed at the end of an interval (in this case, 30 min.) is
the average power (Demand value) for the interval.
The figure below describes the relationship between: Target demand value,
Predicted value, Present demand value, interval and inspection cycle
What do the 400 and 600kW below indicate? The horizontal axis is a time scale and not
power scale. Are they the predicted demand value displayed?

Demand value
0 15 30(min)
* In this case, the demand value at the end of the interval is 500kW.
The demand values calculated at each interval are useful for power
management per day, month or year.
NOTE
* The readings of the demand meter installed by the power company and the
MODEL6300, may not match completely due to a time-lag in the start of
intervals.
