DL1 Pro not logging at 1Khz only at 100Hz

Hi, My DL1 Pro was purchased with the 6g accerometers and the 1KHz logging options. Although I configured it to collect the analog channels at 1Khz it only logged at 100Hz. When I tried to export the CSV file at 1KHz I got each 10ms reading repeated 10 times. Is there an option in the config setup t...

Re: Why does my analog data lag the built-in accelerometer data?

Issue resolved. Was using the accelerometer and the GPS to calculate speed. The DL1 mounting position was rotated last minute so was using the wrong accelerometer axis for the speed calcs.

Thank you.

Why does my analog data lag the built-in accelerometer data?

Hello, I have a DL1-Pro and am logging GPS, internal accelerometers and analog input #2 which is connected to a ribbon switch taped over my brake pedal. While doing some braking testing I noticed that the built-in accelerometer signal reacts before the brake pedal switch is pushed (see attached .jpg...

DL1 Pro Not recording at 1KHz

I have a DL1 Pro with the 1KHz ANA Upgrade. The unit configuration file is set to record 3 analog channels at 1KHz but I get 100Hz samples repeated 10 times. The RUN file shows 1ms data intervals but each 100Hz sample is simply repeated 10 times. Is this what the 1KHz samples means?? Not really an u...

Solved: DL1 Pro not recording frequency

After reformatting the SD card twice and loading config file the DL1 logged the data correctly.
Thanks,

DL1 Pro not recording frequency

I am trying to setup my DL1 to record a wheel sensor on FREQ1 input. I have it on my bench with a 75Hz square wave input with 12V amplitude to Pin "T" of the 19 pin connector. I get no frequency data in the file. Also, the first three analog inputs do collect but only at 100Hx NOT at 1KHz ...

No proper data/time of logged files.

I am logging accelerometer and analog data on a bench test rig I built and not interested in GPS data. The logged .RUN files are saved to the SD card but the data/time stamp on the files is some old default values. Am I correct to assume that the data/time stamp is taken from the GPS data? Or can I ...
