Calibration
We recommend the device be tested for accuracy every two years or after
mechanical impact (e.g., been dropped).
1) Set up for accuracy test:
2) Push and hold Start/Stop Button, turn the power on, then release
the Start/Stop Button. A series of codes will flash on screen,
then “0.0” will display.
