TAKING A MEASUREMENT
Correct Way to Hold the Meter
Our quantum meters offer good accuracy at a low cost, but the user should be aware of potential sources of error. The biggest error is often caused by small changes in the position of the meter. The sensor on the top of the meter must be exactly horizontal for the most accurate measurement.  The correct position for making a measurement is shown at right.

USING THE INSTRUMENT
1.  Turn the dial to the "ON" position.
2.  Hold the meter so that the sensor surface on the top is horizontal.
3.  Hold the meter at eye level to avoid shading the sensor with your head.
4.  The number in the display is the PPF with units of µmol m-2 s-1.  See our FAQ page for a discussion about PPF units and conversions to different units.
5.  Turn the meter off after use to conserve battery power.
