8.2.4.5 [SENSe:]VOLTage:{AC|DC}:RANGe:AUTO
Description:
Enable or disable autoranging for AC and DC voltage measurements
The autoranging range can be adjusted down to less than 10% of the range and can be adjusted upwards to more
than 120% of the range.
Syntax:
[SENSe:]VOLTage:{AC|DC}:RANGe:AUTO {ON|OFF}
[SENSe:]VOLTage:{AC|DC}:RANGe:AUTO?
Parameters:
{ON|1|OFF|0}
Example:
VOLT:AC:RANG:AUTO ON
8.2.4.6 [SENSe:]VOLTage[:DC]:NPLC
Description:
Sets the integration time in terms of the number of power line cycles (PLC) for DC voltage
measurement.
The integration time is the period during which the instrument's analog-to-digital (A/D) converter measures the
input signal samples. A longer integration time gives a higher measurement resolution, but the measurement speed
is slower.
Syntax:
[SENSe:]VOLTage[:DC]:NPLC {<plc>|MIN|MAX}
[SENSe:]VOLTage[:DC]:NPLC? [{MIN|MAX|DEF}]
Parameters:
<plc>:{0.02|0.2|1|10|100}
Example:
VOLT: NPLC 10
8.2.4.7 [SENSe:]VOLTage[:DC]:IMPedance:AUTO
Description:
Enable or disable the automatic input impedance mode for DC voltage measurement
Syntax:
[SENSe:]VOLTage[:DC]:IMPedance:AUTO {ON|OFF}
[SENSe:]VOLTage[:DC]:IMPedance:AUTO?
Parameters:
{ON|1|OFF|0}
Example:
VOLT: IMP: AUTO ON
8.2.4.8 [SENSe:]VOLTage[:DC]:ZERO:AUTO
Description:
Enable or disable the auto zero mode for the DC voltage.
ON: The DMM internally measures the offset after each measurement. This measurement is then subtracted from
the previous reading. This prevents the offset voltage on the DMM input circuit from affecting the measurement
accuracy.
OFF: The instrument uses the last measured zero return measurement and subtracts it from each measurement. It
reads a new zero reading whenever you change the function, range or integration time.
Syntax:
[SENSe:]VOLTage[:DC]:ZERO:AUTO {ON|OFF}
[SENSe:]VOLTage[:DC]:ZERO:AUTO?
Parameters:
{ON|1|OFF|0}
Example:
VOLT: ZERO: AUTO ON
