5.9 Measurement
5.9.1 Operation Modes
The device can perform active, reactive and apparent power and energy measurement in 6, 4 or 3 wire
mode with generation of energy impulses on an impulse output. The mean frequency at the impulse
output is proportional to the sum-power.
There are 8 operating modes for power and energy measurement:
Number
Code
Operation Mode
0
P6
Active power and energy in 6-wire mode
1
P4
Active power and energy in 4-wire mode
2
P3
Active power and energy in 3-wire mode
3
N6
Reactive power and energy in 6-wire mode (natural)
4
N4
Reactive power and energy in 4-wire mode (natural)
5
N3
Reactive power and energy in 3-wire mode (natural)
6
K4
Reactive power and energy in cross-connected (artificial) mode
7
K3
Reactive power and energy in cross-connected (artificial) mode
Operation Mode can be controlled by menu item Measurement / Operation Mode or by remote
commands:
MEASure:OPERatingmode {<param>}
Setting of Operation Mode. Parameter is Operation Mode’s number (0-7) or code (P6-K3).
MEASure:OPERatingmode?
Request for setting of Operation Mode. Replay is Operation Mode’s number (0-7).
5.9.2 Measuring Time Interval (Time Base)
All measured values are evaluated in the interval of the internal Time Base. The interval is defined in
seconds and the default setting is 1s.
Time Base value is saved in configuration and recalled after switch-on of device. Time Base value
can be controlled by menu item Measurement / Time Base or by remote interface commands:
MEASure:TIMEbase?
Request for setting of Time Base. Answer is time in seconds.
MEASure:TIMEbase {<time>}
Setting of Time Base. Parameter is time in seconds.
5.9.3 Division Factor
Division Factors (Current Division Factor and Voltage Division Factor) describe characteristic of input
circuits. They give the input division ratio: (measured voltage) / (voltage lead to the device) i.e. the
product of the device measured value and the division factor value gives the result.
They can be controlled by menu items Voltage Factor and Current Factor in Measurement / Input /
Range menu or by remote interface commands:
SYSTem:DIVision:VOLTage {<factor>}
Setting of the Voltage Division Factor.
SYSTem:DIVision:VOLTage?
Request for the setting of the Voltage Division Factor.
SYSTem:DIVision:CURRent {<factor>}
Setting of the Current Division Factor.
SYSTem:DIVision:CURRent?
Request for the setting of the Current Division Factor.
