Page 26: Measurements Settings
Measurements settings Settings of global features related to measurement. Available setup options depend on device type. Devices with temperature measurement can select between °C and °F. Dew point unit is same as temperature unit. Devices with humidity measurement allow for one of computed values from the list: Dew point, Absolute humidity, Specific humidity, Mixing ratio, Specific enthalpy, or Humidex. -
Page 27: Channels Settings
In case of channel name is left blank, default channel name according to selected language is used. Be aware that after changing channel name, a new channel is created inside ATAL Onlinesensor or ATAL Database. Each channel can have two independent alarms thresholds which can be configured separately. - Page 28 Settings alarm for a channel Each channel allows for configuration of two separate alarms. Alarm mode selects direction of alarm – Lower than limit, Higher than limit, or Disabled. Limit value is a threshold for activation of alarm. Alarm is activated when measured value exceed selected limit for a quantum of time set by Delay option.
- Page 29 enabled disabled separately alarm settings. Image above illustrates how settings of alarms works. There is set alarm limit 50 % with delay 10 sec and hysteresis 2 %. At the beginning is alarm not activated because measured value does not exceed limit value for whole delay time.

Recalculation of measured values Measured values can be re-calculated using linear equation. This option can be enabled when some correction of measured values is needed. Enabling this option does not affect calibration of Digi probes or device itself. Alarms settings Alarm setting page allows for globally enable or disable audible and optical LED signalisation. - Page 31 System alarms System alarms are used to diagnose functionality of measurement chain including device or connected probes. A system alarm notifies about failure of the device including connected probes. On the other hand, alarms on measurement values indicate an issue with technology monitored by the device.
