CONF COMMANDS
CAUTION: The following commands are used to set the configuration of the DQ-4000 and
should not be changed until you have a thorough understanding of the operation of the
instrument and the effect of these parameters. The DQ-4000 would display erroneous load, if
the parameters are not set correctly.
4.7 CSS (Sample Size) Command
Function: Sets (or reports) the sample size to average for noise reduction
Summary: The DQ-4000 performs sample averaging to reduce noise that may be present
in the raw data. You may set the sample size to average to any number in the
range 1 to 15. Note that higher values may reduce the data rate of the output.
The CSS command is valid for when individual sensor is selected using S1, S2,
S3 or S4 command. It is not valid when all sensors are selected using S0
command.
Example: CSS 10 (sets the averaging sample size to 10)
CSS (reports the currently set value of CSS)
4.8 CPS (Packet Size) Command
Function: Sets (or reports) the packet size
Summary: Sets or reports the packet size used in the process of generating the measured
frequencies. In general, a larger packet size will let you obtain finer resolution.
However, the larger packet sizes will reduce the sampling rate of your
measurements.
The CPS command is valid for when individual sensor is selected using S1, S2,
S3 or S4 command. It is not valid when all sensors are selected using S0
command.
Example: CPS 32 (sets packet size to 32)
CPS (reports currently set packet size)
