Queries the power line cycle integration rate for DC voltage measurements.

Enables or disables auto range for DC voltage measurement. The default is ON.

Queries whether DC voltage auto range is enabled.

Selects the upper measurement range for DC voltage measurement. The range is documented as 0 to 1000.

Queries the upper measurement range for DC voltage. This command is documented as the query form of the DC voltage range setting.

Queries the state of the DC voltage reference. The manual says it returns 0 or 1.

Queries the programmed DC voltage reference value. A reference must be enabled and specified first, otherwise an error may occur.

Specifies the reference value for AC voltage measurements. The command is used to establish a reference value for the specified function; reference can also be set via the coupled :ACQuire command.

Specifies the reference value for DC voltage measurements.

Acquires the measurement input signal and stores it as the reference value for the specified function. It is typically used to zero the display, and is only valid when the instrument is on that measurement function.

Controls whether the AC voltage reference is enabled or disabled. When enabled, the displayed reading includes the programmed reference value; when disabled, it does not.

Acquires the present measurement input signal and stores it as the reference value for DCV. It is functional only on the specified measurement function; otherwise an error occurs.

Enables or disables the DCV reference state. When enabled, the displayed reading includes the programmed reference value; when disabled, it does not.

Queries whether auto range is enabled or disabled. Auto ranging automatically selects the most ideal measurement range, and enabling it is coupled to the manual range command.

Sets the integration rate in power line cycles for AC current measurements.

: CURRent:AC:NPLCycles <n> Set NPLC for ACI

Sets the current measurement integration rate in power line cycles. The documented values are 0.1, 1, and 10, corresponding to Fast, Medium, and Slow.

: CURRent:DC:NPLCycles <n>

Sets auto ranging for AC current measurements.

Sets the AC current measurement range using the expected reading as an absolute value. It selects the most sensitive range that will accommodate that expected reading.

Sets auto ranging for DC current measurements.

Sets the DC current measurement upper range for the specified function.

Specifies the reference value for AC current measurements. It is used to establish the reference for the specified function; when a reference is set with this command, the corresponding query returns the programmed value.

Specifies the reference value for DCI relative measurements. The command is coupled to :ACQuire; when reference is set this way, :REFerence? returns the programmed value.

Acquires the present measurement input signal and stores it as the reference value for current AC. It is typically used to zero the display and is only valid when the instrument is in the specified measurement function.

: CURRent:AC:REFerence:ACQuire

Enables or disables the current AC reference for the specified function. When enabled, the displayed reading includes the programmed reference value; when disabled, it does not.

Acquires the current measurement input signal and stores it as the reference value for the specified current function. It is typically used to zero the display.

Enables or disables reference for DC current. When enabled, the displayed reading includes the programmed reference value; when disabled, it does not.

Sets the NPLC integration rate for resistance measurements. The integration period is based on power line cycles and can be set to fast, medium, or slow values.

Sets auto ranging for resistance measurements. When enabled, the instrument automatically selects the most suitable measurement range and updates the range value shown by :RESistance:RANGe <n>.

Sets the measurement range for resistance by specifying the expected reading as an absolute value. The instrument then selects the most appropriate range that accommodates that reading.

Specifies the reference value for resistance measurements. The reference is used when reference/relative mode is enabled; the reading becomes input signal minus reference.

Enables or disables the reference for resistance measurements. When enabled, the displayed reading includes the programmed reference value; when disabled, it does not include the reference value.

Acquires the input signal and stores it as the reference value for resistance measurement, typically to zero the display. It is only valid in the specified measurement function; otherwise an error occurs.

Specifies the reference value for the frequency measurement function. The reference is used for relative measurements when reference is enabled.

Sets the voltage threshold range used to specify the expected input level. The instrument then automatically selects the most ideal current or voltage threshold range.

Acquires the measurement input signal and establishes it as the reference value for the selected function. It is typically used to zero the display.

Enables or disables reference for the frequency function. When enabled, the displayed reading includes the programmed reference value; when disabled, it does not.

:FREQuency:REFerence:STATe <b>
:FREQuency:REFerence:STATe <b> Control reference for FREQ

Specifies the reference value for the PER measurement function. The instrument uses the reference when relative measurement is enabled.

Sets the voltage threshold range used to specify the expected input level. The instrument then automatically selects the most ideal current or voltage threshold range.

Acquires the present measurement input signal and stores it as the reference value for period measurements. It is typically used to zero the display, and is only functional when the instrument is in the specified measurement function.

Enables or disables the reference for period measurements. When enabled, the displayed reading includes the programmed reference value; when disabled, it does not.

Query command used to obtain the last available reading. It does not affect instrument configuration and does not trigger a measurement; it returns the same last reading until a new reading is available.

Selects the trigger event control source. The control source can be set to the instrument default internal trigger, bus trigger, or manual external trigger.

Queries error messages from the error queue. The response may be "NO ERROR!" if no errors have occurred, or "BUS:BAD COMMAND." for a bad or misspelled command.
