      If your Alnor Measuring Instruments display is blank, here are a few things to check: 1. Ensure the unit is turned on by pressing the I/O key. 2. Check the batteries. They might be low, dead, or have dirty contacts. Replace or clean them as needed. 3. If you're using an AC adapter, make sure it's properly connected.

    What to do if '------' appears on the display for velocity or volume on Alnor EBT731?

      Angela WestAug 19, 2025
      If you see "------" on the display for velocity or volume on your Alnor Measuring Instruments, it means a valid temperature reading is required to perform the standard or actual velocity/volume correction. To fix this, ensure a temperature-measuring probe is connected to the meter. Alternatively, you can set “Temp Source” to “Entered” in the Actual/Std menu and manually enter the temperature.
