UIT2400 INSTRUMENTATION MANUAL REV A, May 2020 

13 OF 18 

light level decreases to .5mW/cm2(5e-4) or less, and an Error Level  (8e-5) (Display turns red) 

will occur when the light falls below .08 mW/cm2(8e-5) 

3. For High and Range, the error level must be greater than the warning level. 

i.e target is 1 mW/cm2 (1e-3) the warning must be larger than 1e-3 ie 3e-3 or 3 mW and the 

error must be larger than the warning and target i.e. .5 mW/cm2. 

 

Other Settings

 

15L. Start-Up App:

 Allows the user to change the display style from the default “Home 

Screen” to Meter, Trend, Cloak, Survey or Light stack automatically when the device turns on. 

 

15M. Use Scientific Notation  ON / OFF:

 

Scientific notation ON uses an exponent to show the decimal place, when off, a prefix is used.

 

Examples: 

 

On (1.35 e-3 W/cm2), Off (1.35 mW/cm2)

 

On (4.78e-6 W/cm2), Off (4.78 uW/cm2)

 

 

For help understanding scientific notation: see chart:  

 

15N. Dim Display After time settings

: Sets the time in minutes before the display will dim to 

save on battery life.  Times range from 5 min- 60 min and also includes Never. 

 

15O. Turn Off Display After time settings

: Sets the time in minutes before the display will 

shut off to save on battery life.  Times range from 5 min- 60 min and also includes Never. 

 

Maintenance

 

15P. Set Date and Time

Allows the user to set the date and time which are then used to 

create file names and date/time stamps on the saved .csv files as discuss in 16 above.
