MeshGuard User’s Guide
5.3.4 Zero Calibration
When “CAL” and “go” are displayed in alternation, and “ZERO” is
shown, the MeshGuard is ready to perform a zero calibration.
Press [Y/+]. The LCD displays “go.”
The display counts down from 10 to 0.
After the countdown reaches 0, the LCD displays “dn,” for “done.” The
reading should show 0 (zero). Otherwise, repeat the zero calibration.
