iRIS 220 / iRIS 320, V1.19 User Guide - 34

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.
