  • Page 6: Check Calibration

    If you have a fresh battery and the instrument still does not indicate a proper calibration, return it to DELMHORST for service. See Service for Your Meter section. When the battery is removed and then reconnected, all the LEDs will flash for a few seconds, then the meter will turn itself off.
  • Page 7: Understanding Your Readings

    READINGS Refer to the chart on page 5 for interpretation of meter readings. Since the J-LITE displays %MC in a range between two val- ues, corrections for wood temperature, pin, and species have less impact on the accuracy of the meter readings, especially below 12%.
