This command returns the “Maximum Allowable Variation” (MAV) for the label weight you specify. The MAV value comes from tables in Fourth Edition NIST Handbook 133 (2005), Appendix A.
Syntax
MAV "lookup_table", "unit_of_measure", label_quantity
The "lookup_table" parameter specifies which lookup table to use for calculating MAV. Valid options are:
|
"lookup_table" |
explanation |
|
"2-5" |
Table 2-5. Maximum Allowable Variations (MAVs) for Packages Labeled by Weight |
|
"2-9HF" |
"Homogenous Fluid when Filled" group from |
|
"2-9" |
"All Other Products" group from |
The "unit_of_measure" parameter specifies the measurement unit for the label_quantity parameter. It also determines which measurement unit will be used to express the MAV value that is returned by this command. This parameter is not case sensitive. Valid options are:
|
"unit_of_measure" |

The label_quantity specifies the number of ounces, pounds, grams or kilograms on the package label. This value must be a number greater than 0. When specifying a label weight in ounces for table 2-5, this value should not be greater than 17.28.
Return value
This command returns a number.
If a MAV value could not be returned for the parameters you specified, this command returns the number 0.
Notes
If a MAV value could not be returned for the parameters you specified, this command puts the error message in a string variable named MySVar "MAV_Error".
Examples
MAV "2-5", "oz", 3
This formula looks up the MAV for a 3-ounce package in Table 2-5 and returns the number 0.25.
Because the label weight was expressed in ounces, the result (0.25) is expressed in ounces.
MAV "2-5", "lb", 2
This formula looks up the MAV for a 2-pound package in Table 2-5 and returns the number 0.07.
Because the label weight was expressed in pounds and table 2-5 was used to find the MAV, the result (0.07) is expressed in pounds.
MAV "2-9HF", "lb", 2
This formula looks up the MAV for a 2-pound package in the "Homogenous Fluid when Filled" group from Table 2-9 and returns the number 0.5.
Because the label weight was expressed in pounds and table 2-9HF was used to find the MAV, the result (0.5) is expressed in ounces.
MAV "2-9", "g", 500
This formula looks up the MAV for a 500-gram package in the "All Other Products" group from Table 2-9 and returns the number 28.3.
Because the label weight was expressed in grams, the result (28.3) is expressed in grams.
MAV "2-9", "kg", 1.25
This formula looks up the MAV for a 1.25-kilogram package in the "All Other Products" group from Table 2-9 and returns the number 28.3.
Because the label weight was expressed in kilograms, the result (28.3) is expressed in grams.
