[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”, “20”, or “200”.
[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 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
”.
