= IsTareWtChanged =
Checks whether the formatted tare weight is different from the last time IsTareWtChanged was called.

{{{
bool IsTareWtChanged(int nScale, int nLen = 7);
}}}

== Parameters == 

 * nScale - scale number
 * nLen - length to format the weight

== Return Value ==

 * Returns true if the formatted tare weight of the specified scale is changed, or false if the formatted weight is the same as the last time IsTareWtChanged 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.

== Examples ==

{{{
if(IsTareWtChanged(1))
{
    DisplayText(0, 0, GetChangedTareWt(1));
}
}}}
