Occasionally Wagner Meters Handheld Moisture Meters require adjustment. However, the process of checking zero points and calibration is very simple.
Note: Wagner Meters are originally calibrated at the factory. Type and amount of use will determine how long this original calibration will last. A calibration reference block is available for the customers who must check their meter's calibration often. Anytime that the moisture meter is not reading correctly on that calibration block, it should be sent into the factory for calibration.
