REF (Relative Value Mode):
In the measurement mode, short press button to enter the Relative Value mode (Set the current value to 0), and short press it again to exit the mode.

Calibration Mode

Place the device on the absolute horizon, continuously long press button for three times to enter the self-calibration mode (see figure 1); CALO flashes on the screen, short press button to confirm to enter the auto zero calibration (see figure 2).
Rotate the device 90 degrees, press flashes on the screen; short press button and CAL1 button to confirm to enter the auto zero calibration (see figure 3). Rotate the device 90 degrees, press short press button and CAL2 flashes on the screen; button to confirm to enter the auto zero calibration (see figure 4). Rotate the device 90 degrees, press and CAL3 flashes on the screen; short press button button to confirm to enter the auto zero calibration (see figure 5).
