X-320M™ User's Manual
Slope
In many cases, the inputs must be scaled to represent “real-world” measurements. X-320M™ reads
the “raw” value from each input, and calculates the number that represents the “real-world”
measurement that the user is actually interested in. This real-world value (referred to as the “Scaled
Value” in this manual) is calculated using the following linear formula:
Scaled Value = Slope * Input + Offset
The Scaled Value is displayed on the
Status Page.
It is also used to determine alarm conditions,
and is shown in email messages.
“Slope” in the formula above is provided by the user and is entered in this field. The value is used to
scale the input to the range of detected condition.
The default value for this field is
1
.
When the Slope is set to 1 and Offset is 0 (default values), the Scaled Value equals the Input Value.
Offset
The “Offset” is used for the “zero” measurement. The default value for this field is
0
. When both the
slope and offset are set to their default values, the Scaled Value equals the Raw Input.
Units
This drop-down allows you to specify the units for the wind speed sensor. The units selected will be
determined by the slope and offset used to calibrate the sensor. The following units of measure are
available:
-
in:
This option is used if your Slope and Offset are set to measure rain accumulation in
inches.
-
mm:
This option is used if your Slope and Offset are set to measure rain accumulation in
millimeters.
High Alarm
This setting is used to set the trigger point for a high alarm condition. The alarm is triggered when
the value at the sensor exceeds the High Alarm Value. The default High Alarm is
20
.
Monitored Value:
This drop-down menu allows you to select which monitored value will generate the alarm conditions.
The Monitored Values are the following:
-
Past Hour:
This will generate an alarm if the rain accumulation in the last hour reaches the
High Alarm set point.
-
Total Today:
This will generate an alarm if the rain accumulation since midnight reaches
the High Alarm set point.
-
Past 7 Days:
This will generate an alarm if the rain accumulation during the past 7 days
reaches the High Alarm set point.
-
Total Rain:
This will generate an alarm if the rain accumulation total reaches the High Alarm
set point.
