1) POWER
Push to turn the scale on or off.
2) ZERO
Used to zero the scale. Zero range depends on standard.
3) NET/GROSS
When in NET mode, pushing this provides a temporary (4 seconds)
gross weight reading.
4) TARE IN/OUT
When in GROSS mode, pushing TARE will zero any weight on the scale
which causes the scale to go into the NET mode. When in NET mode,
pushing TARE will clear the TARE value and the scale will revert to the
GROSS mode.
5) TEST
When pushed, this causes a display segment check, and provides battery
and RCAL tests.
