[SENSe<Sensor>:]AVERage:COUNt 

<count>

Sets the number of readings that are averaged for one measured value. The higher the
count, the lower the noise, and the longer it takes to obtain a measured value.

Average count is often also called averaging factor, but it designates the same thing,
i.e the number of measured values that have to be averaged for forming the measure-
ment result.

Averaging is only effective, if 

[SENSe<Sensor>:]AVERage[:STATe]

 

ON

 is set.

Parameters:

<count>

Range: 

1  to  65536

*RST: 

4

Example: 

AVER:COUN 1

Manual operation: 

See 

"<Value>"

 

on page 52

[SENSe<Sensor>:]AVERage:COUNt:AUTO 

<state>

Sets the mode for determining the average count.

Parameters:

<state>

ON

Auto averaging: the averaging factor is continuously determined
and set depending on the level of power and other parameters.

OFF

Fixed filter: the previous, automatically determined averaging
factor is used.

ONCE

An averaging factor is determined by the filter automatic function
under the current measurement conditions and is then used in
the fixed filter mode.
*RST: 

ON

Manual operation:
