Hello all,
I have some(many) "error" with reading of Vibrating Wires (range 600-1200Hz). i put a Measurement Delay but nothing seems to work well.
With manual reader (GK404 or sisgeo type) no problem appears, the value is stable. I use a DT80G serie3 and the measurement is very degraded , (sometimes i can read the real value same with my manual reader, some other times i read about 2600Hz (variable)

maybe someone can help me with this range of frequence (about 800Hz) ; it s very problematique for many sensors

thank you in advance for any help you could bring (and sorry about my bad english language)

Hi basile,

There is a headphone socket on the top of DT80G logger. Please try to listen a ping sound on every reading attempt.
If the sound is clear then the setting of measurement delay and sample period are good.
But if the sound is not good, you will need to do trial and error on measurement delay and sample period values.

Please refer to page 326 of DT8x manual.

Best regards,
Rudy Gunawan
