The valid range of Pressure input is from 600 to 1120 hPa. (420 - 840 mmHg)
●
When “Atmospheric Correction” in “Initial Setting 1” has been set to “1. AUTO”
or “4. NIL”, “ ” is displayed to the left of the pressure value on the correction
menu screen. When “ ” is on the screen, the pressure cannot be changed.
If “Atmospheric Correction” in “Initial Setting 1” has been set to “3.ppm
INPUT”, no pressure is displayed on the correction menu screen.

Once set, the pressure is displayed at the center of the top of the
measurement screen.
●
The factory initial of pressure is “1. AUTO”.
●
Once set, the pressure remains in memory even after the power is turned off.
●
Pressure correction is based on 1013 hectopascals (hPa).
●
If this instrument is used without correcting the pressure, a distance error per
100 m is about - 0.3 mm per -10 hPa as a pressure difference from 1013 hPa.
(For more accurate values, see page 82.)
