Option 4
When this option is selected you will be prompted to enter a scaling multiplier. This multiplier is used to
convert the raw input into engineering units.
> Multiplier=
Option 5
When this option is selected you will be prompted to enter a scaling offset. This offset is added to the scaled
engineering value.
> Offset=
Option 6
When this option is selected you will be prompted to enter a logging multiplier to convert from engineering
units to an integer value to storage in the logging memory.
> Log Multiplier=
For example, if you need to log a measurement that is accurate to two decimal places you will need to enter
a logging multiplier of 100.
NOTE: Care needs to be taken in the selection of an appropriate logging multiplier because the iRIS
logs data as signed 16-bit integer values (-32768 to 32767). This means that the maximum scaled
value multiplied by the logging multiplier must not exceed 32767.
Option 7
When this option is selected you will be prompted to enter a logging rate (in minutes) for the sensor.
> Log Rate=
If you wish to log digital data on change of state you can enter a value of 0. If this parameter is left at 0 for
Analog sources, they will not be logged.
Option 8
Select this option to display the Alarm Configuration menu for the sensor.
Option 9
Select this information to view the logged data for the sensor. You will be prompted to enter the number of
samples you would like returned
NOTE: This option is only available when the terminal session is through the RS232 port, not through
a GPRS/CDMA-1X terminal session.
