METER support FAQ

Fesili masani e uiga i tusi lesona, resitalaina, ma lagolago mo lenei ituaiga.

  • How do I connect TEROS sensors to a data logger?

    TEROS sensors typically utilize a 3.5mm stereo plug or stripped wires. They connect directly to METER ZENTRA data loggers or can be integrated into third-party loggers using SDI-12 or DDI serial communications.

  • What software is required for METER data loggers?

    METER ZL6 and similar data loggers are configured and managed using ZENTRA Utility (available for desktop and mobile) or the ZENTRA Cloud web tulaga.

  • How often should METER sensors be calibrated?

    Many METER soil sensors come factory-calibrated for mineral soils and may not require frequent recalibration. However, specific instruments like the AQUALAB series or localized soil setups may benefit from periodic verification or custom calibration service, which METER Support can facilitate.

  • Where can I find firmware updates for my device?

    Firmware updates for loggers and handheld devices are typically available through the ZENTRA Utility software or on the downloads section of the METER Group webnofoaga.

  • Who do I contact for repairs or RMA?

    For troubleshooting, repairs, or Return Merchandise Authorization (RMA), contact the METER support team at support.environment@metergroup.com or call their support line at +1 509-332-5600.
