= IsWtUnitsChanged =
Checks whether the weight units such as "lb" or "kg" is different from the last time IsWtUnitsChanged was called.

{{{
bool IsWtUnitsChanged(int nScale);
}}}

== Parameters == 

 * nScale - scale number

== Return Value ==

 * Returns true if the weight units of the specified scale is changed, or false if the weight units is the same as the last time IsWtUnitsChanged was called.

== Remarks ==

The value returned is from an internal memory buffer from the last MnBdRead? that received a weight for the specified scale. An application program should be structured properly for this data to be updated when needed.

== Example ==

{{{
if(IsWtUnitsChanged(1))
{
     DisplayText(0, 0, GetCurWtUnitsLabel(1));
}
}}}
