• Flag
The meanings of the flags are given on the table below. The flags are valid during
FIFO data output. The flags are undefined for other cases.

No
Yes
Indicates that the decimal position or unit information was changed
during measurement.
1
No
Yes
Indicates that the FIFO acquiring interval was changed during
measurement.
0
No
Yes
Indicates that the internal process took too much time (computation,
for example) and that FIFO dropout occurred.
The bits that have “–” for the flag column are not used. The value is undefined.

BINARY value 0 to 8 is entered in the upper and lower 4 bits of a byte (8 bits) for the alarm
status. The binary values 0 to 8 correspond to H (high limit alarm), L (low limit alarm), h
(difference high-limit alarm), l (difference low-limit alarm), R (high limit on rate-of-change
alarm), r (low limit on rate-of-change alarm), T (delay high limit alarm), and t (delay low limit
alarm) as follows:
0: no alarm, 1: H, 2: L, 3: h, 4: l, 5: R, 6: r, 7: T, and 8: t.
