When Memory Full; Time To Start & Time To End; Total Time Span; Enabled - Microedge Instruments iLog Series User Manual

When Memory Full

If you want the logger to stop logging when the memory is full select Stop logging. If you
want the logger to continue logging and overwrite the oldest data with the new data (FIFO),
you choose Continue logging.
Time to Start & Time to End
These two fields specify the desired time the logger will start logging data and the time to
stop logging data.
Making changes to the Time to Start/End will affect Total Time Span fields mentioned later.
If you have selected the Continue logging field, when the memory is full, both start time and
end time will move forward accordingly.

Total Time Span

These fields are an alternate way to specify the total logging time from the start time you
specified above.
Changes made on these fields will affect Time to End field.
Channel Settings:

Enabled

Check this field to enable this channel for logging.

Channel Range

This field specifies the measurement range the channel will use. Different channel types have
different input range selections. Please refer to Channels and Sensor Connections chapter
for details.

Description

This field specifies the name or the description of the channel (maximum of 30 characters).

Equation

This field specifies the equation used for the channel. Different channel ranges have different
default equations. Please refer to Channels and Sensor Connections chapter for details.
In order to convert a process signal to a correct measurement value an equation must be
applied to the channel.
For example, if you want to use the 0 – 5 VDC channel to record a battery voltage output,
the logger will first convert the battery voltage values to digital values and save them in the
memory. Later when all data are downloaded to a computer, SiteView will use equation
"VoltageDC" to convert the digital values back to voltage values.
