Configuration
There are three relays available and their behaviour can be configured on the
Relays
page.
For each relay the following properties can be configured:
•
Enabled:
If checked, indicates that the relay should respond to breath test results
and enables remaining configuration items for the relay.
•
Min:
If a result is greater than this value the relay should turn on for the configured
duration. If the minimum value is 0.00 for example, the relay should turn on if the
value of the result is greater than or equal 0.00.
•
Max:
If a result is less than this value the relay should turn on for the configured
duration. If the maximum value is 0.00 the relay should turn on if the value of the
result is less than or equal 0.00.
•
Duration:
If the relay is enabled and a breath test result falls within its configured
range, the relay should fire for a number of seconds equal to the configured
duration.
The
Relay Status
indicates if the relay is currently
ON
or
OFF
.
There are three buttons on this page that briefly activates the relays.
NOTE
It is possible for breath test results near a configured value for the relays to act differently
depending on whether the actual value was slightly above or below the displayed value.
This is due to the nature of the analog input from the fuel cell and possible rounding
behaviour below the precision of the displayed value.
In this situation the instrument will
not
activate two relays in the situation where one
relay shares a nonzero maximum with the minimum value from another relay.
