[SENSe:]{RESistance|FRESistance}:APERture:ENABle {OFF | ON} [, (@<ch_list>)]
[SENSe:]{RESistance|FRESistance}:APERture:ENABle? [(@<ch_list>)]
Enables the setting of integration time in seconds (called aperture time) for 2-wire and 4-wire resistance meas-
urements. If aperture time mode is disabled (default), the integration time is set in PLC (power-line cycles).
Parameter is shared between RESistance and FRESistance measurements. Setting or querying the parameter
with the RESistance version of this command is identical to setting or querying it with the FRESistance ver-
sion.
Parameter Typical return
{OFF | ON}. Default: OFF 0 (OFF) or 1 (ON)
Enable aperture time mode, set the aperture time to 300 ms:
RES:APER:ENAB ON
RES:APER 300E-03
or
FRES:APER:ENAB ON
FRES:APER 300E-03
– The CONFigure:{RESistance|FRESistance}, MEASure:{RESistance|FRESistance}, [SENSe:
{RESistance|FRESistance}:NPLCycles, and [SENSe:]{RESistance|FRESistance}:RESolution commands disable the
aperture mode (these commands select an integration time in number of power line cycles).
– This parameter is set to its default value after a Factory Reset (*RST command).
