ADVanced:NTOLerance <n>
[:SENSe[1]]:AVERage:ADVanced:NTOLerance <n>Set filter noise window
:SENSe2:AVERage:ADVanced:NTOLerance <n>Set filter noise window
Parameters <n> = 0 to 105 Specify filter noise tolerance in %
DEfault 5

MAXimum 100
Query :NTOLerance? Query filter noise tolerance value
Description When the advanced filter is enabled (see “STATe” below) a noise window is used
with the average filter. This command is used to specify the noise window. If
readings are within the noise window, the average filter operates normally. If,
however, a reading falls outside the window, the buffer is flushed of old readings
and filled with the new reading.
ADVanced[:STATe] <b>
[:SENSe[1]]:AVERage:ADVanced[:STATe] <b>Enable or disable advanced filter
:SENSe2:AVERage:ADVanced[:STATe] <b>Enable or disable advanced filter
Parameters <b> = 0 or OFF Disable advanced filter
1 or ON Enable advanced filter
Query [:STATe]? Query state of advanced filter
Description This command is used to enable or disable the advanced filter. When enabled, the
noise window is used with the averaging filter. When disabled, the noise window is
not used.
Median filter commands
MEDian:RANK <NRf>
[:SENSe[1]]:MEDian:RANK <n> Set median filter rank
:SENSe2:MEDian:RANK <n> Set median filter rank
Parameters <n> = 0 to 5 Specify rank value for median filter
DEFault 1
MINimum 0
MAXimum 5
Query RANK? Query median filter rank
Description The median filter is used to pass the middle-most reading from a group of
readings that are arranged according to size. This command is used to specify the
rank, which determines the number of reading samples for the filter process.
The number of reading samples are determined as follows:
Sample readings = 2n + 1
Where: n is the selected rank (1 to 5).
MEDian[:STATe] <b>
[:SENSe[1]]:MEDian[:STATe] <b>Enable or disable channel 1 median filter
:SENSe2:MEDian[:STATe] <b> Enable or disable channel 2 median filter
Parameters <b> = 0 or OFF Disable repeat filter
1 or ON Enable repeat filter
Query [:STATe]? Query state of repeat filter
