What the LogTag recorded

What the LogTag indicated

2 readings above 20ºC, return to normal, 8
readings below 0ºC, return to normal, 4

readings above 20ºC, return to normal

Neither alert condition is met.
The maximum number of consecutive

out-of-spec readings is only 2 (5 required, the 8

readings below 0ºC do not count towards alert

readings).

The total out-of-range events equals 2 + 4 = 6.

The alert condition is 7 total, so the alert does
not go off, as again the 8 readings below 0ºC

do not count towards alert readings.

No Flashing Red Alert Indicator

4 readings above 20ºC, return to normal, 4

readings above 20ºC

The first alert condition is not met, as the the

maximum number of consecutive out-of-spec

readings is only 4 (5 required.)

The second alert condition however IS met
since the total out-of-range events equals 4 + 4

= 8. The alert condition is 7 total. so the alert

DOES go off.

Flashing Red Alert Indicator

Separate alert conditions are useful if you expect the monitored product to encounter
temperatures lower than the lowest possible alert temperature. In this case a flashing
alert indicator may not necessarily indicate an unfavourable condition was encountered.
In programs where such conditions are monitored the lower alert should be turned off.
