The alarm lasted up to Point 5, when the temperature dropped below the set hysteresis
(temperature limit – hysteresis). At this moment was active alarm cleared and e-mail sent.
When alarm occurs, alarm messages will be sent. In case of power failure or device reset (e.g.
changing the configuration) will new alarm state evaluated and new alarm messages will be
sent.
Measuring
Page contains settings of the measuring part of the device. Settings can be saved only if
jumper inside device is closed. Fields in this page are shown according device type.
It is possible set visibility of measured values on device LCD. Display can be switched off.
Units of measured and computed quantities are selectable by fields Temperature unit and
Computed value. Field Pressure value for computed values is required to set for proper
calculation of computed quantities. Mode of CO
2
concentration measuring can be set by item
Average CO
2
measuring mode – „SLOW mode“. Because principle of CO
2
concentration
measurement depends on atmospheric pressure (altitude), it is recommended for accurate
CO
2
measurement set Altitude for CO
2
compensation.
Whole measuring range of CO
2
concentration (0 to 2000/10000ppm) can be divided into
three areas. Using three-color LED the transmitter indicates, in which of these areas the
measured value is. LED configuration is possible via fields Yellow LED limit and Red
LED limit.
