4.14 “LE” - Enable Log Intervals

If logging is started (

command) it will continue based on the interval lengths and iterations of

the log list (

command).

*LE

Log intervals enabled.

*Datalogger#1,2009,94,1004,35,3.22,23.36,9986.394,25.0,1

4.15 “M” - Display Current Monitor Mode Setting

The monitor mode will display arrays as they are stored in memory in the course of logging. This

is useful where a test is being conducted and immediate display of logged values would be

helpful. Use the

(Section 4.16) and

(Section 4.17) commands to disable or enable the use

of the Monitor mode.

Monitor mode enabled.

4.16 “MD” - Disable Monitor Mode

Arrays will not be sent to the host computer as they are logged.

*MD

Monitor mode disabled.

4.17 “ME” - Enable Monitor Mode

Arrays will be sent to the host computer as they are logged.

*ME

Monitor mode enabled.

4.18 “MS” – Display Current Memory Status

Maximum number of readings (8000 or 16000) will be displayed, along with the wrap format

and status of reading synchronization.

*MS

8000 readings maximum

Logging will not stop when memory is full

Readings are synchronized to the top of the hour.
