Measuring Modes Available: Sensor Type / Device

Energy - Measurements in Joules.
Exposure - Used to measure the sum of the energy (for Pyroelectric and Photodiode sensors).
Fast Power - Power measurement mode using fast sampling rate; used to measure laser modulation and flicker of LED light sources (for Photodiode sensors).
Low Freq Power - Power measurement mode optimized for VCSELs and similar pulsed sources, where low pulse rate and high pulse peak power would cause problems if measuring in regular power mode.
Power – Measurements in Watts.
Pulsed Power - Can display instantaneous power of a laser pulse. Power is calculated from energy when the length of the pulse is known (for Thermopile sensors).
Track - Used to measure beam position and beam size while measuring power (for Thermopile sensors).
