Ashcroft support FAQ

Häufig gestellte Fragen zu Handbüchern, Registrierung und Support für diese Marke.

  • How often should I recalibrate my Ashcroft pressure instrument?

    Routine inspection is recommended at least once every 6 months, with recalibration or zero adjustment performed as necessary to maintain accuracy.

  • How do I adjust the zero on an Ashcroft A2 transmitter?

    Depending on the enclosure model, zero adjustment is accessed via a side pot behind a sleeve or a top pot under a threaded cap. Use a small trim pot tool to adjust the zero within ±10% of full scale.
