Here s an example of how to determine the attenuation correction factor that needs to be set in the FieldMaxII TO meter If a 1 W laser beam is focused through an attenuator that has an attenuation factor of 50 then to get a true laser measurement value the correction factor in the FieldMaxII TO instrument needs to be set to 2 In other words since only half the power of the beam is transmitted through the attenuator the measured result must be doubled to obtain a true laser measurement The Atten button is used to initiate several activities Toggle the state of Attenuation Correction mode if the button is pressed for less than one second Enter Edit mode and select the attenuation factor 1f Setup Local is pressed beforehand View the attenuation factor if the button is pressed for one second or more 32 Hold Button Functions Auto Zero Operation Pressing the Hold button toggles between freezing the power reading and associated indicators on the LCD and displaying live measurements Pressing the Auto button instructs the FieldMaxII TO to select the best measurement range for the incoming signal Pressing the Zero button causes the analog circuitry to zero its internal settings by running a zero cycle If Auto Ranging is not active the meter will zero the currently selected range If Auto Ranging is active the meter will zero all available ranges for the attached sensor When a zero procedure i
