The Kestrel 4200 is capable of storing up to 1600 data points for each measurement. To review the data, 
press the   button while viewing a chart. A cursor will appear on the most recent data point. Press the   

and   buttons to scroll through the data points. The date and time at which the data was stored will be 

displayed at the bottom of the screen, and the data value will be displayed at the top of the screen.  Hold 
down the   or   button to scroll quickly through the data points.
Press the   or   button to review the data for the other measurements. Please note that the cursor will 

remain at the same date and time.  If new data is stored while viewing chart data, the entire chart will shift

Press the   button to return to the Chart Mode.

The Kestrel 4200 is set up to display 12 Measurements (some are 

calculations) in 3 Modes. 
The Measurements are listed here with their corresponding screen 

icon. In addition to these Measurements and Modes, there are also 3 

User Screens, which simultaneously show 3 current measurements, 

and the Date & Time Screen, which gives the current date and 

time. Use the   and   buttons to scroll through the various 

Measurements, followed by the 3 User Screens and the Date/Time 

Screen. Any of these screens can be turned off so that you can 

customize your Kestrel Meter to show the screens that your application 

requires. (See the Measurements section in the Main Menu.)
The Modes are displayed below. Use the   and   buttons to scroll 

through the various Modes. From any mode, you may still scroll to a 

different Measurement by pressing the   and   buttons.

Current - Displays the instantaneous reading.
