[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.
MIN = 3 Hz. MAX = 200 Hz. [Stored in volatile memory]
[SENSe:]DETector:BANDwidth? [MINimum|MAXimum]
Query the ac filter. Returns “+3.000000E+00”, “+2.000000E+01”, or
“+2.000000E+02”.
[SENSe:]ZERO:AUTO {OFF|ONCE|ON}
Disable or enable (default) the autozero mode. The OFF and ONCE
parameters have a similar effect. Autozero OFF does not issue a new
zero measurement until the next time the multimeter goes to the
“wait-for-trigger” state. Autozero
ONCE issues an immediate zero
measurement. [Stored in volatile memory]
[SENSe:]ZERO:AUTO?
Query the autozero mode. Returns “0” ( OFF or ONCE ) or “1” ( ON ).
INPut:IMPedance:AUTO {OFF|ON}
Disable or enable the automatic input resistance mode for dc voltage
measurements. With
AUTO OFF (default), the input resistance is fixed
at 10 M Ω for all ranges. With AUTO ON , the input resistance is set to
>10 G Ω for the 100 mV, 1 V, and 10 V ranges. [Stored in volatile memory]
INPut:IMPedance:AUTO?
Query the input resistance mode. Returns “0” ( OFF ) or “1” ( ON ).
ROUTe:TERMinals?
Query the multimeter to determine if the front or rear input terminals
are selected. Returns “
FRON ” or “ REAR ”.
