Specifies the measurement resolution in digits or in absolute units. This VI is polymorphic. To change the selected instance of this polymorphic VI, right-click the VI and choose Select Type followed by Resolution in Digits or Absolute Resolution.

Use the pull-down menu to select an instance of this VI.

niDMM Configure Measurement Digits

Configures the common properties of the measurement.

These properties include Function, Range, and Digits Resolution.

instrument handle identifies a particular instrument session.

You obtain the instrument handle parameter from niDMM Initialize or niDMM Initialize With Options.

/images/reference/en-XX/help/370384V-01/cenum.gif

Function specifies the measurement function used to acquire the measurement. NI-DMM sets the Function property to this value.

/images/reference/en-XX/help/370384V-01/cdbl.gif

Resolution in Digits specifies the resolution of the measurement in digits. The PXIe-4080/4081/4082 uses the resolution you specify. The NI 4065 and NI 4070/4071/4072 ignore this parameter when Range is set to Auto Range ON (-1.0) or Auto Range ONCE (-3.0). The default is 5.5 Digits.

NI-DMM sets the Digits Resolution property to this value.

Note  NI-DMM ignores this parameter for capacitance and inductance measurements on the NI 4082 and NI 4072. To achieve better resolution for such measurements, use the Number of LC Measurements to Average property.

Range specifies the range for the measurement. Sets the range for the function specified in the Function control. Range values are coerced up to the closest input range. When frequency is specified in the Function parameter, you must supply the minimum frequency expected in the Range parameter. For example, you must type in 100 Hz if you are measuring 101 Hz or higher.

Refer to the Device Overview in the Digital Multimeters Help for a list of valid ranges. NI-DMM sets the Range property to this value. The default is 0.02 V.

Note  The NI 4050, NI 4060, and NI 4065 only support Auto Range when the trigger and sample trigger are set to IMMEDIATE.
AUTO RANGE ON (-1.0) NI-DMM performs an Auto Range before acquiring the measurement.
AUTO RANGE OFF (-2.0) NI-DMM sets the Range to the current Auto Range Value and uses this range for all subsequent measurements until the measurement configuration is changed.
AUTO RANGE ONCE (-3.0) NI-DMM performs an Auto Range before acquiring the next measurement. The Auto Range Value is stored and used for all subsequent measurements until the measurement configuration is changed.

error in describes error conditions that occur before this VI runs. If an error occurred before this VI runs, the VI passes the error in value to error out. This VI runs normally only if no error occurs before this VI runs. If an error occurs while this VI runs, it continues and sets its own error status in error out. Use niDMM Error Message to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

/images/reference/en-XX/help/370384V-01/cbool.gif

status is TRUE (X) if an error occurred before this VI ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI ran. The default is FALSE.

/images/reference/en-XX/help/370384V-01/ci32.gif

code is the error or warning code. The default is 0. If status is TRUE, code is a negative error code. If status is FALSE, code is 0 or a warning code.

/images/reference/en-XX/help/370384V-01/cstr.gif

source describes the origin of the error or warning and is, in most cases, the name of the VI that produced the error or warning. The default is an empty string.

/images/reference/en-XX/help/370384V-01/iio.gif

instrument handle out returns a handle that you use to identify the instrument in all subsequent instrument driver VI calls.

/images/reference/en-XX/help/370384V-01/ierrcodeclst.gif

error out contains error information. If error in indicates that an error occurred before this VI ran, error out contains the same error information. Otherwise, it describes the error status that this VI produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.

status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.

/images/reference/en-XX/help/370384V-01/ii32.gif

code is the error or warning code. The default is 0. If status is TRUE, code is a negative error code. If status is FALSE, code is 0 or a warning code.

niDMM Configure Measurement Absolute

Configures the common properties of the measurement. These properties include Function, Range, and Absolute Resolution.

Function specifies the measurement function used to acquire the measurement. NI-DMM sets the Function property to this value.

/images/reference/en-XX/help/370384V-01/cdbl.gif

Resolution specifies the absolute resolution of the measurement. The PXIe-4080/4081/4082 uses the resolution you specify. The NI 4065 and NI 4070/4071/4072 ignore this parameter when Range is set to Auto Range ON (-1.0) or Auto Range ONCE (-3.0). The default is 0.001 V.

NI-DMM sets the Absolute Resolution property to this value.

Range specifies the range for the measurement. Sets the range for the function specified in the Function control. Range values are coerced up to the closest input range. When frequency is specified in the Function parameter, you must supply the minimum frequency expected in the Range parameter. For example, you must type in 100 Hz if you are measuring 101 Hz or higher.

Refer to the Device Overview in the Digital Multimeters Help for a list of valid ranges. NI-DMM sets the Range property to this value. The default is 0.02 V.
