20.2 Function Specifications
────────────────────────────────────────────────────
1. Voltage, current, active power measurements (
U, I, P)
(when using the 9600, 9601, 9602)
Measurement type
Analog computation within the input unit of U , I , and P for each
channel
For 1P3W and above, the SUM value of
U , I , and P is computed
digitally in the main unit.
Accuracy
For SUM value, with respect to value computed measurement
values (
U , I , and P channels):
U , I :
±
1dgt., P:
±
3dgt. max.
Range
The range of the SUM value of U and I more than 1P3W is same
as the range for each channels (for P , see elsewhere)
2. Waveform peak measurement (|
Up|, |Ip|)
(when using the 9600, 9601, 9602)
Measurement type
Analog peak hold circuit in the input unit (maximum of absolute
value) (for each input unit, either voltage or current can be
selected)
Accuracy
Determined by specification of each input unit
3. Apparent power, reactive power measurement (
S, Q)
(when using the 9600, 9601, 9602)
Measurement type
Digital computation from measurement values ( U , I , and P ) for
each channels. Computation expression selectable from three
variants (type1, type2, and type3). (See elsewhere)
Accuracy
±
1dgt with respect to value computed measurement values ( U , I ,
and P channels)
SUM: maximum of
±
3 dgt
Range
Same as active power (units: VA, var)
Effective input range
When the measurement values ( U , I , and P ) of the channels are
within the valid input ranges
Polarity display
Apparent power no polarity
Reactive power when the current leads voltage: "-",
when the current lags voltage: unsigned
For calculation (type 2, 3): no polarity
4. Power factor measurement (
λ)
(when using the 9600, 9601, 9602)
Measurement type
Calculated from the measured value ( U , I , P ) for each channel
Formula is shown elsewhere. The accuracy in this case is a
maximum of
±
3 dgt. with respect to the value computed from the
measurement values ( U , I, and P ).
Display range
0.0000 to
±
1.0000
Polarity display
When the current leads the voltage: "-",
when the current lags the voltage: unsigned
For calculation (type 2, 3): no polarity
