• The valid range of Temperatue input is from -30°C to +60°C.
• When “Atmospheric Correction”in “Initial Setting 1”has been set to “1 .AUTO”or
“4.NIL”,“ ” is displayed to the left of the temperature value on the correction menu
screen.When “ ”is on the screen, the temperature cannot be changed.
If “Atmospheric Correction”in “Initial Setting 1”has been set to “3.ppm INPUT”,
no temperature is displayed on the correction menu screen.
• 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.
