Table 11. Temperature alarm specifications
Specification
8 (one per digital I/O line)
Each alarm controls its associated digital I/O line as an alarm output. The input to each
alarm may be any of the analog temperature input channels. When an alarm is enabled, its
associated I/O line is set to output (after the device is reset) and driven to the appropriate
state determined by the alarm options and input temperature. The alarm configurations
are stored in non-volatile memory and are loaded at power on. Alarms function both in
data logging mode and while attached to USB.
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)
