S activate an automatic zero on start up function,
S activate an automatic zero tracking function,
S linearize the input signal with a third order polynomial,
S activate various digital filters. Available filters include
those with cut-off frequencies below 1 Hz, fast-settling
filters for dynamic measurements, notch filters and
mean value filters.
Use MSV? to read out the current measured value. The
format of the measured value (ASCII or binary) is set
with the COF command. You can also use the COF com­
mand to activate automatic measurement output. The
measured values are transmitted in the following format,
subject to the COF command:

Adaptive interference suppression

Whatever the mode of operation, you can use the ADF
command to activate automatic interference suppression
with adaptive filters. Interference frequencies are auto­
matically found during measurement and suppressed by
comb filters and averaging. The maximum filter settling
time can be limited with the TMA command.
