3.3. Stability Considerations
Once a <ZERO>, <TARE> or <PRINT> key is pressed the unit
waits for a stable valid reading before performing the associated
operation. If the weight readings remain unstable or invalid due
to some diagnostic error for longer than 10 seconds, the
operation is cancelled and the STABLE ERROR message is
displayed.
