    Why won't my METER Measuring Instruments SC-1 calibrate, even after multiple attempts?
    • J
      John NelsonSep 12, 2025
      If your METER Measuring Instruments SC-1 will not calibrate, even after multiple attempts, it may not be in thermal equilibrium. Leave the sensor head at ambient conditions for 15 min and try again.

    How to fix a METER Measuring Instruments SC-1 that does not turn on?
    • A
      austinbryceAug 23, 2025
      If your METER Measuring Instruments SC-1 does not turn on, check that the batteries are inserted correctly. If it still does not turn on, replace the batteries.

    What to do if I get a Sensor Head Failure error on my METER SC-1?
    • D
      Douglas PeckAug 27, 2025
      If you encounter a Sensor Head Failure error on your METER Measuring Instruments, first verify the sensor head is securely connected to the serial port receptacle. If the error persists, restart the reading. You may also navigate to the Configuration tab, select Diagnostics, and press ENTER to save a Scan record. Contact Customer Support with the Scan record results ready for review.

    Why am I getting a 'Firmware is corrupted!' error on my METER SC-1, and how do I fix it?
    • R
      Raven JosephAug 28, 2025
      A 'Firmware is corrupted!' error on your METER Measuring Instruments may occur if the firmware was not loaded properly or an update is needed. Before reloading the new firmware, download any data. Check metergroup.com/sc1-support for a new firmware version.

    What should I do if the conductance readings on my METER SC-1 are not as expected?
    • D
      Daniel HebertAug 29, 2025
      If the conductance readings on your METER Measuring Instruments are not what you expected, verify porometer accuracy. You can also recalibrate the sensor head, and clean the sensor head. If the Tefol n filter is wet or dirty, replace the filter.

    Why does an infinity symbol appear instead of a measurement on my METER SC-1 Measuring Instruments?
    • M
      Matthew TerrySep 18, 2025
      An infinity symbol appears in place of the measurement because the stomatal conductance measurement is greater than or equal to 6,000 mmol/(m2s). Remove water from the leaf and repeat the measurement.

    Why does the equilibration shake down period between measurements extend past 75 seconds on my METER Measuring Instruments?
    • H
      hawkinsdanielSep 12, 2025
      If the equilibration shake down period between measurements extends past 75 s on your METER Measuring Instruments, check the integrity of the round rubber seal that caps the measurement chamber, as an air leak may have developed. Test for leaks by placing fresh desiccant in the desiccant chamber and leaving the sensor head undisturbed for 2-3 days. Use the diagnostics screen to check the RH of the unopened sensor head. If the RH is >10%, there is a leak.

    What causes 'Too much drift' error in METER SC-1 and how to solve it?
    • J
      John SanchezSep 8, 2025
      If you are getting a 'Too much drift' error on your METER Measuring Instruments, it means that stable calibration readings were not achieved in 10 readings. Leave the sensor head at ambient conditions for 15 min and try again.

    How to resolve a persistent high RH reading error on METER SC-1?
    • P
      pmoranSep 5, 2025
      To resolve a persistent high RH reading error on your METER Measuring Instruments, check the desiccant and replace it if needed. The Tefol n filter may also be clogged, so replace the filter.
