• Once set, the temperature is displayed at the center of the top of the measurement screen. • The factory initial of temperature is “1. AUTO”. • Once set, the temperature remains in memory even after the power is turned off. • Temperature correction is based on 15°C. If this instrument is used without correcting the temperature, a distance error per 100m is about -0.1mm per +1°C as a temperature difference from 15°C. A distance error per 100m is about 0.1mm per -1°C as a temperature difference from 15°C. (For more accurate values, See “13.4 Error when no Atmospheric Correction is made”.) 7.3 Changing the atmospheric pressure The atmospheric pressure setting can be changed only when “Atmospheric Correction” has been set to “ATM INPUT” in “Initial Setting 1”. Example: Setting the pressure to 900hPa Press [F4] [CORR] in mode B. (If the instrument is in mode A, press [F5] [MODE] to enter mode B.) Press [F4] [ ] to move the cursor to “4.PRESS” and press the [F5] [SELECT] to enable the temperature to be changed. Clear the exiting values by pressing [CLEAR] key. Input 900 by pressing the numeric keys. SELECT CORRECTION 1. PRISM CONST * 0mm 2. SHEET CONST * 0mm 3. TEMP : +15°C 4. PRESS : 1013hPa 5. ppm * 0ppm SELECT CORRECTION 1. PRISM CONST * 0mm 2.

MEAS TARGET 0 SET DISP MODE • The valid range of Pressure input is from 600 to 1120hPa. (420 - 840mmHg) • 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 100m is about -0.3mm per -10hPa as a pressure difference from 1013hPa. (For more accurate values, see “13.4 Error when no Atmospheric Correction is made”.) 7.4 Changing the ppm value The ppm value can be changed only when “Atmospheric Correction” has been set to “ppm INPUT” in “Initial Setting 1”. “TEMP” and “PRESS” are not displayed.
