the true condition; the meaning of the signals is as follows:
<s1>
bit 0
minimum weighing operation signal
bit 1
blocked tare signal
bit 2
preset(1)/self-weighing(0) tare
signal
bit 3
"center zero" signal
<s2>
bit 0
not used
bit 1
stable weight signal
bit 2
overload signal
bit 3
not used
<s3>
bit 0
entered tare signal
bit 1
not used
bit 2
invalid weight
bit 3

<s4>
bit 0
