Hi,

I have just received a dataTaker and upon connection to the PC, starts making a rather high pitch sound. Not talking about signal noise - an actual audible noise.

I do not currently have a PC Card installed, would that make a difference. I used another dataTaker in the past which did not make the same noise.

Thanks for any help...

Good morning jlaird,

The DT800 does have an internal buzzer that you can use for audible warnings. Try connecting to the DT800 and sending the command FACTORYDEFAULTS.
Then clear out the internal drive.

If you can't clear the problem then you might need to return the logger for repair.

Cheers,
Roger

I'm supposing that what you intend for "high pitch sound" is the internal DT800 switching power supply / voltage adapter. So far DT800 is the only Datataker logger that does this; old DT5xx series and DT8x are "silent" logger (excepting the relays "symphony" during acquisition).

So for DT800 a light hiss, going higher when the current consumption increases, has to be considered normal. Unfortunately some old and deaf dataTaker users (like me) no longer detects this kind of high pitch sound...

Thanks guys. It is that high pitch sound you speak of Teo. It does definitely increase once recording is underway. Just wanted to confirm that is normal and that the unit is not about to explode.

Cheers
