"approximately 0.7 mA.\n"
2 all "Secondary Auto Range Value" FL45_ATTR_SECONDARY_AUTO_RANGE_VALUE ViReal64 g
"Always returns the actual range the DMM is currently using for the "
"secondary measurement. The secondary measurement function is always "

"(1) If the secondary measurement function is diode, this attribute returns "
"the maximum forward voltage of a junction at approximately 0.7 mA\n"
2 all "Resolution" FL45_ATTR_RESOLUTION ViReal64 gs attrResolutionRangeTable
"Specifies the measurement resolution in digits of precision.\n"
" Setting this attribute to higher values increases the measurement "
"accuracy. Setting this attribute to lower values increases the "
"measurement speed. I\n"
"\n"
"Notes:\n"
"\n"
"(1) If the secondary measurement function is enabled, then this attribute "
"also specifies the resolution of the secondary measurement.\n"
2 all "Trigger Source" FL45_ATTR_TRIGGER_SOURCE ViInt32 gs attrTriggerSourceRangeTable
"Specifies the trigger source. After you call one of the FL45_Measure, "
"FL45_Read, or FL45_Initiate functions, the DMM waits for the trigger you "
"specify with this attribute. After it receives the trigger, the DMM waits "
"the length of time you specify with the FL45_ATTR_TRIGGER_DELAY attribute. "
" The DMM then takes a measurement.\n"
2 all "Trigger Delay" FL45_ATTR_TRIGGER_DELAY ViReal64 gs
"This attribute specifies the value you want to use for the trigger delay. "
"Express this value in seconds.\n"
"\n"
"The trigger delay specifies the length of time the DMM waits after it "
"receives the trigger and before it takes a measurement.\n"
"\n"
"The FL45 allows only auto-delay enabled or no delay at all. You cannot "
"set the FL45 to a manual delay value other than 0.0. The driver reserves "
"negative values for configuring the DMM to calculate the trigger delay "
"automatically.\n"
"\n"
"Defined Constant Values:\n"
"FL45_VAL_AUTO_DELAY_ON - Auto-delay on\n"
"\n"
"Valid Manual Range: 0.0 (seconds)\n"
"\n"
"Default Value: FL45_VAL_AUTO_DELAY_ON\n"
"\n"
"Notes:\n"
"\n"
"(1) Setting this parameter to FL45_VAL_AUTO_DELAY_ON configures the DMM to "
"calculate the best trigger delay before each measurement.\n"
2 all "AC Minimum Frequency" FL45_ATTR_AC_MIN_FREQ ViReal64 gs
"Specifies the minimum frequency component of the input signal for AC "
"measurements. The value of this attribute affects instrument behavior only "
"when you set the FL45_ATTR_FUNCTION attribute to an AC measurement.\n"

"AC+DC Volts: 20.0 to 100.0E3 Hz\n"
"AC+DC Current: 20.0 to 20.0E3 Hz\n"
"\n"
"When you set the Measurement Function to AC Current or to AC+DC Current "
"and set the Range to a value greater than 0.1 A, then the maximum value "
"the DMM allows for this parameter decreases to 2.0 kHz.\n"
"\n"
"Notes:\n"

"20.0 Hz.\n"

"Attributes for acquiring data on multiple triggers and multiple "
"measurements per trigger.\n"
" "
1 all "Miscellaneous"
"Miscellaneous attributes.\n"
" "
1 all "Function Modifiers"
"Attributes that control the FLuke 45 function modifiers. A function "
"modifier causes the meter to modify the normal operation of a measurement "
"function (or perform an action on a measurement) before displaying a "
"reading. For example, the relative modifier causes the meter to display "
"the difference between a measured value and the relative base."
2 all "Decibel Modifier"
"This group specifies attributes for turning on/off and configuring a "
"decibel modifier. A modifier causes the DMM to modify the normal "
"operation of a measurement function (or performs an action on a "
"measurement) before displaying a reading.\n"
3 all "dB Mode" FL45_ATTR_DB_MODE ViInt32 gs attrDbModeRangeTable
"Specifies the decibel modifier to use. The DMM must be in a voltage "
"measurement function before this attribute can be set to a decibel "
"modifier.\n"
"\n"
"When you enable a decibel modifier, the readings you obtain from the "
"FL45_Measure, FL45_Read, and FL45_Fetch functions are in the decibel "
"units you configure with this function.\n"
"\n"
"Notes:\n"
"\n"
"(1) You can use the decibel modifiers for only voltage measurement "
"functions.\n"
3 all "dB Reference Impedance" FL45_ATTR_DB_REF ViInt32 gs attrDbRefRangeTable
"Specifies the reference impedance used for the decibel modifier.\n"
"\n"
"If you set the Decibel Mode to dB Power, the valid impedance values are 2, "
"4, 8, or 16 ohms.\n"
"\n"
"Note:\n"
"\n"
"(1) This parameter affects instrument behavior only when you enable one of "
"the decibel modifier's calculation modes.\n"
2 all "Hold Modifier"
"This group contains attributes that control the DMM's hold modifier. The "
"hold modifier configures the DMM to take a new measurement only when the "
"input signal is stable and 'hold' that measurement on the display. This "
"feature can be particularly advantageous in difficult or hazardous "
"circumstances when you might want to keep your eyes fixed on the probes, "
"and then read the display when it is safe or convenient to do so."
3 all "Hold Enable" FL45_ATTR_HOLD_ENABLE ViBoolean gs Boolean_values
"Specifies whether to enable the hold modifier. VI_TRUE enables the "
"modifier, and VI_FALSE disables the modifier. The hold modifier "
"configures the DMM to take a new measurement only when the input signal is "
"stable and 'hold' the measurement on the display. This feature can be "
"particularly advantageous in difficult or hazardous circumstances when you "
"might want to keep your eyes fixed on the probes, and then read the "
"display when it is safe or convenient to do so.\n"
"\n"
"Notes:\n"
"\n"
"(1) Use the FL45_Hold() function to force a new reading to be displayed. "
"When a new, stable reading is detected, a beep is emitted, and the display "
"is automatically updated.\n"
"\n"
"(2) The FL45_Hold() function should be called before the trigger occurs. "
"For example if you are using the software triggering mechanism. Then the "
"order of function calls should be:\n"
"\n"
" FL45_Initiate ();\n"
" FL45_Hold ();\n"
" FL45_SendSWTrigger ();\n"
3 all "Hold Threshold" FL45_ATTR_HOLD_THRESHOLD ViInt32 gs attrHoldThresholdRangeTable
"Specifies the hold measurement threshold. The DMM takes a new measurement "
"only when the input signal is as stable as you specify with this "
"attribute.\n"
"\n"
"Notes:\n"
"\n"
"(1) This attribute affects instrument behavior only when you set the "
"FL45_ATTR_HOLD_ENABLE attribute to VI_TRUE.\n"
" "
2 all "Compare Modifier"
"This group specifies attributes for turning on/off and configuring the "
"compare modifier. The compare provides an easy way to determine if a "
"reading falls within a designated range of values.\n"
3 all "Compare Enable" FL45_ATTR_COMPARE_ENABLE ViBoolean gs Boolean_values
"Specifies whether to enable the compare modifier. VI_TRUE enables the "
"compare modifier, and VI_FALSE disables the compare modifier.\n"
"\n"
"The compare modifier provides an easy way to determine if a reading falls "
"within a range you specify. You specify the range with the High Value and "
"Low Value parameters. Enabling the compare modifier automatically enables "
"the hold modifier. Disabling the hold does not affect the compare "
"modifier.\n"

3 all "Min Max Mode" FL45_ATTR_MIN_MAX_MODE ViInt32 gs attrMinMaxModeRangeTable
"Specifies whether to enable the min-max modifier and whether the min or "
"max value should be displayed. Enabling this modifier automatically "
"disables auto-ranging.\n"
"\n"
"Each time the DMM takes a measurement, it compares the measured value "
"against the minimum and maximum values. If the measured value is less "
"than the minimum value, the DMM saves the measured value as the new "
"minimum value. If the measured value is greater than the maximum value, "
"the DMM saves the measured value as the new maximum value.\n"
"\n"
"Note: \n"

"values.\n"

3 all "Relative Enable" FL45_ATTR_RELATIVE_ENABLE ViBoolean gs Boolean_values
"Specifies whether to enable the relative modifier. When the relative "
"modifier is enabled, the DMM returns all measured values relative to a "
"base value. You specify the base value with the FL45_ATTR_RELATIVE_BASE "

"present reading is 14.10 volts, the DMM returns -0.90 volts as the result "
"of the FL45_Measure, FL45_Read, and FL45_Fetch functions.\n"
"\n"
"Enabling the modifier automatically disables auto-ranging. When the "
"relative modifier is first enabled, the DMM stores the last valid reading "

"relative base is set to 0.0.\n"
3 all "Relative Base" FL45_ATTR_RELATIVE_BASE ViReal64 gs
