Measurement Configuration Commands
[SENSe:]DETector:BANDwidth {3|20|200|MINimum|MAXimum}
Specify the lowest frequency expected in the input signal. The multimeter
selects the slow, medium (default), or fast ac filter based on the frequency
you specify. = 3 Hz.
MIN
[SENSe:]DETector:BANDwidth? [MINimum|MAXimum]
Query the ac filter. Returns "3", "20", or "200".
[SENSe:]ZERO:AUTO {OFF|ONCE|ON}
Disable or enable (default) the autozero mode. The
parameters have a similar effect. Autozero
zero measurement until the next time the multimeter goes to the
"wait-for-trigger" state. Autozero
measurement. [Stored in volatile memory]
