5.11 Impulse Input
The impulse input Fin of the device can be used for direct comparison of any reference / working
standard to this device.
Condition is that both devices measure same signals under same configuration (type of energy,
included channels, constant) therefore setting of these parameters for this device is available.
Integration time allows configure length of the measurement.
State of the measurement and result are indicated on Impulse Input screen and can be also obtained
by remote interface commands.
The impulse input functionality can be controlled by submenu “Measurement / Energy / Impulse /
Fin Meas/Test” (described in above chapters) or by these remote interface commands:
SYSTem:ENERgy:IN:STARt?
Request for the state of the device impulse input measurement.
Reply is: 0 (for OFF), 1 (for running measurement), 2 (for finished measurement) or negative number
(-1, -2) for measurement error.
SYSTem:ENERgy:IN:STARt
Start of new impulse input measurement.
SYSTem:ENERgy:IN:ERRor?
Request for the result (last measured error value) of the impulse input measurement.
SYSTem:ENERgy:IN:TIMe?
Request for the setting of integration time parameter. Returned value is in unit seconds.
SYSTem:ENERgy:IN:TIMe {<intTime>}
Setting of integration time parameter in unit seconds.
SYSTem:ENERgy:IN:STATe?
Request for the state of the device impulse input Fin – proportional to one type of energy. Reply is: 0
(for ACTIVE POWER), 1 (for REACTIVE POWER) or 2 (for APPARENT POWER).
SYSTem:ENERgy:IN:STATe {0|1|2}
Setting of the state of the device impulse input Fin – proportional to one type of energy. Parameter is:
0 (for ACTIVE POWER), 1 (for REACTIVE POWER) or 2 (for APPARENT POWER).
SYSTem:ENERgy:IN:CHANnel?
Request for the setting of the individual channel selection for impulse input Fin functionality related to
the energy. Reply are three (in a sequence for channels L1, L2 and L3) values 0 or 1 (0 denounce for
switched-off and 1 for switched-on given channel selection) separated by a commas (e.g. “1,0,1”).
SYSTem:ENERgy:IN:CHANnel {0|1|OFF|ON},{0|1|OFF|ON},{0|1|OFF|ON}
Setting of the individual channel selection for impulse input Fin functionality related to the energy. The
parameters value (in a sequence for channels L1, L2 and L3) is ON or 1 for switched-on state and OFF
or 0 for switched-off state of given channel selection. This setting influences the summing up of the
individual channels into the value of frequency compared with the frequency of the device impulse intput
Fin.
SYSTem:ENERgy:IN:CONStant?
Request for the setting of the constant of the device impulse input Fin. Reply is real number in unit 1/Ws
(1/VAs, 1/VArs).
SYSTem:ENERgy:IN:CONStant {<constant>}
Setting of the constant of the device impulse input Fin. Parameter <constant> is in the unit of 1/Ws
(1/VAs, 1/VArs).
