Logging Mode; Downloading Data; Field Activation - Microedge Instruments iLog Series User Manual

If the logger is configured with a sampling interval of 4 seconds or faster, it will operate in
fast sampling mode. When a logger is in fast sampling mode, it has the following conditions:
1. The logger needs external power supply (supplied by USB or AUX port) for the logging
period.
2. Any communications with the logger will interrupt its operation and stop the recording.
3. The number of enabled channels depends on the sampling intervals:
1 channel with 20 ms interval
2 channels with 30 ms interval

Logging Mode:

This parameter specifies if the logger will stop or continue logging when the memory is full.
Available settings are Stop Logging and Continue Logging.
If Logging Mode was set to Stop Logging, the logger will stop logging at the End Time. If
Logging Mode was set to Continue Logging, the logger will continue logging and the
oldest data will be overwritten by the new data.

Downloading Data

The data in the logger can be transferred to the computer by SiteView software. If the logger is
not in Fast Sampling mode, the data can be downloaded any time even when the logger is still
recording. If the logger is in Fast Sampling mode, downloading the data will make the logger
stop logging at the time when it received the downloading command.
The readings saved in the logger are ADC digital values, and will be converted to physical
measurements by SiteView software after they are downloaded to the computer. The data
conversion is handled by an equation that may be embedded in SiteView software or a script
provided by the user.

Field Activation

iLog data logger comes with an on-board activation button which can be used to activate/initiate
the logging session in the field.
To activate the logger for new session:
1. With the SiteView software, open the configuration dialog of the logger, and set the start
time to any time the desired start time will never reaches. Click OK button to save new
settings to the logger.
