Configure device; configura-

tion for channel 1 in OUT1

and for channel 2 in OUT2

During the transient response (e.g., following a

configuration command), the fluctuating mea-

sured values may exceed the minimum and

maximum values. Therefore, at the start of ac-

quisition delete the minimum and maximum

values using command 3200

hex and/or

3300

hex. The minimum value is set to the larg-

est positive number (7FF

hex = 32767dec) when

deleting. The maximum value is set to the larg-

est negative number (8000

hex = -32768dec).

Mean-value

Selects mean-value generation. After

every conversion, the measured value

is saved in a mean-value memory via

which the mean-value is generated.

The memory size can be selected with

the mean-value option. E.g., for a 16-

sample mean-value, the mean-value

is generated using the last 16 mea-

sured values.

Selects the measuring range

Set all unused bits to 0.

If invalid parameters are specified in the pa-

rameter word, the command will not be execut-

ed. The command is acknowledged in the input

words with the set error bit.
