Option 2

When this option is selected you will be prompted to enter a name for the sensor (maximum 10 characters).
This name will be displayed on the iRIS LCD sensor screens.

> Name (max 10)=


Option 3

When this option is selected you will be prompted to enter a number representing the processing mode to
apply to the measurements.

> Mode (0..4)=

Valid modes are:

Mode

Name

Description

0

Instant

Logs only the most recent sample

1

Full Period Average

Logs the average of all samples taken over the logging period

2

Event

(Only valid for pulse input sources) Logs only non-zero samples.
If the logging rate is 0, then any pulse is logged immediately.
If the logging rate is > 0, then the total accumulated in the period is
logged only if it is not zero. In this mode, if there was no sample
logged at the last expected log time, a zero sample is also logged,
time stamped with last expected log time/date. This is required for
some time series management purposes.

3

Scalar Average
(for Wind Direction)

Logs the average of all samples taken over the logging period, but
uses scalar calculations to calculate the average.

4

1 min Average

Logs the average of all samples taken over the one minute period
prior to the data being logged. This is useful for sensors that are
powered on a timed basis using a digital output and some
averaging is still required. In this case, using the Full Period
Average (1) would give an incorrect value.



After selecting the mode, you will then be prompted to configure the extended datalogging options by
entering in a number that represents a set of option “flags”.

> Flags (+1:Min +2:Max +4:Dev +8:Flow/Vol)=

The number entered is the sum of the extended logging options that you want to enable.
See the table on the next page for a listing of all the valid options.


Flag Value 1 = Log Minimum Value sampled in log period
Flag Value 2 = Log Maximum Value sampled in log period
Flag Value 4 = Log Standard Deviation of samples in log period
Flag Value 8 = Log calculated Flow Rate (in l/s) over log period (only pulse types, source = 5, 6, 7 or 8).

Or log Accumulated Volume for sensors with an analog or frequency source.
