Read out the current measured value via
MSV?
. The format of the measured
value (ASCII or binary) is set with the
COF
command. You can also use the
COF
command to activate the automatic measurement output. The measured
values are transmitted in the following format, depending on the
COF

mand:

Adaptive interference suppression
Regardless of the mode of operation, you can use the
ADF
command to acti
vate automatic interference suppression with adaptive filters. Interference fre
quencies are automatically found during the measurement and suppressed by
comb filters and averaging. The maximum filter settling time can be limited with
the
TMA
command.

Digital output
Use the digital output as a limit switch, for example. The gross or net value is
monitored depending on the parameters for the
LIV
command.
Gross or net value ≥ switching threshold: low output voltage (≤ 1 V)
Gross or net value < switching threshold: high output voltage (≥ 6 V)
You can also use the
POR
command if you deactivate the limit value function
(
