Topcon Synergy GM-50 series - 12 Setting Atmospheric Correction; 12.2 Setting of Atmospheric Correction Value

12-2
12 SETTING ATMOSPHERIC CORRECTION
• If the weather correction is not required, set the ppm value to 0.
12.2 Setting of Atmospheric Correction Value
 How to set temperature, pressure and humidity value directly
Measure the temperature, pressure and humidity surrounding the instrument beforehand.

• Factory setting for humidity input is "OFF". In this case, atmospheric correction factor is calculated
assuming humidity is 50%. To input arbitrary value for humidity, set humidity input to "ON" in
advance.
see Section 6.4.8 “Humidity Input ON/OFF Setting”.
Example: Temperature: 26°C, Pressure:1017hPa, Humidity: 45%
