For every sensor, a description, up to 15 symbols can be set. These descriptions will appear in
the monitoring page, conditions page, XML/JSON data, SMS and e-mail alerts.
7.2.3.2.
Digital inputs
For every digital input, a description, up to 15 symbols and states up to 15 symbols can be set.
These descriptions will appear in the monitoring page, conditions page, XML/JSON data, SMS
and e-mail alerts.
7.2.3.3.
Analog inputs
For every analog input, a description, up to 15 symbols can be set. These descriptions will
appear in the monitoring page, conditions page, XML/JSON data, SMS and e-mail alerts.
For every analog input, fields “Unit”, “Multiplier” and “Offset” are available to convert the raw
voltage/current into meaningful engineering units. The shown value is calculated by:
DV[Un] = (AV – OF) * MU
Where:
DV – displayed value;
Un – unit;
AV – real analog voltage from source;
MU – multiplier in dimension [parameter/Volt];
OF – offset.
Example:
For humidity sensor HIH-4000-003 following parameter (coming from datasheet) should
be set for fine work:
Unit
- %RH
Offset
- 0.826
Multiplier
- 31.74, the value is inversed of slope parameter (1/0.0315);
If the output voltage of this sensor is 3.198V on the monitoring page will be shown
75.28% RH:
75.28 = (3.198 – 0.826) * 31.74
By default and after “Factory default settings” procedure:
Unit
- V
Offset
- 0.00
Multiplier
- 1.00
