Hi,

I seem to be unable to put my DT800 to sleep. When I stop a program (logging) and disconnect from the DT800 it seems to be still acquiring something. It will continue to do this until the internal battery runs out of power.

I am using Delogger 4 Pro. Can anyone help me?

Much Thanks,
Sean

Hi Sean,

There are two things that will do this,

1/ Having the DT800 connected to an Ethernet connection.
2/ Not turning off the house keeping.

To fix,

1/ Unplug the Ethernet connection.
2/ Turn of the house keeping /k

If you are storing your logger for any period of time then please disconnect the internal battery.

Regards,
Roger

Just to let others know, I found the problem. The Statistical Report Schedules must not be at every second. So I just changed the RS1S line for RS1H and now it is only using 9 uA when in sleep mode. MARVELOUS!!!

Hi again! I'm trying hard to save power here and I want to use the DataTaker 800 with an external 12 V Battery. The Battery will also power sensors but thru a relay controlled by a digital output (1DSO).

I feed the DT800 thru the =/- Ext Bat terminals and I plugged an multi meter to check the current consumption of the DT800. At the beginning it was near 150 mA and it is slowly going near 125 mA. It does not consume uA like in the manual. I unplugged the RS-232 cable, there is no Ethernet connection, so what is wrong? Can you help? Thanks.

Good afternoon Sean and Peter,

1/ Statistical schedule.

I have just tested the code and it is sleeping regardless of the speed that is set in the statistical schedule.

The speed of the statistical schedule sets the rate at which the sample are taken for the statistical report. As the program does not use any stats then he S schedule does not run and the logger can sleep. If you were using the statistical channel option and sampling every second then the dataTaker would not have enough time to use sleep mode.

2/ Power consumption. If you are connected to the mains power and forcing sleep mode then you are probably measuring the battery charge current.

Cheers,
Roger
