Logging start methods
Alarm when input temperature > T1

Alarm when input temperature > T1, reset alarm when input temperature goes below T2

Alarm when input temperature < T1

Alarm when input temperature < T1, reset alarm when input temperature goes above T2

Alarm when input temperature is < T1 or > T2

T1 and T2 may be independently set for each alarm.
Disabled, digital I/O line may be used for normal operation

Enabled, active high output (digital I/O line goes high when alarm conditions met)

Enabled, active low output (digital I/O line goes low when alarm conditions met)


Configurable:
Start Logging on Power Up – Logging begins 5 seconds after power on to allow

hardware to settle.
Start Logging on Button – Device is idle on power on. Press and hold the button until

the LED turns on to begin logging. The first sample is acquired 1 second after the LED
turns on unless less than 5 seconds have elapsed since power on.
Start Logging at Specified Time – Device is idle until the real-time clock indicates

the time is equal to or greater than the specified time, at which time the LED turns on. The
first sample is acquired 1 second after the LED turns on unless less than 5 seconds have
elapsed since power on.
