Hi,

I've used two dataTaker after some months. I've bought a new 6V battery (3.3 V is ok), I've connected current transformer, I've set DT80 each 5s and I've started my datalogging.

I've seen immediately a strange battery's discharge (supplied by external current transformer) and, after few hour, datalogging stopped because level internal battery went down to 5,5V.

So I've connected an external 12V battery at "+" e "-" to the "B" "C" "+" "-" connector without any DT80 reply (only a flashing led). I've measured 0,2V at internal battery terminal with 12V external battery connected. What's happening?

Giovanni

Good morning Giovanni,

When you first get your logger you should connect the green 4 way plug with the link and connect the plug pack then leave connected to external power for about a day so the lead acid battery can charge.

If you had the USB or network cables connected then the logger will not be able to use sleep mode so the internal battery will last about 3 hours. When you connect an external 12V battery, this should charge will slowly charge the internal 6 VDC battery.

The red LED is the attention LED that tell you some thing needs to be looked at. In this case it will be a power failure. Depending on the firmware the job may not load and run.

If it has V8 or above firmware then the program by default load and run. If the firmware is less that V8 then you need to run the command RunJobOnReset"" (is the name of the job you want to run). It would be better to upgrade the firmware.

Cheers,
Roger
