The X1 position is the most sensitive. Typical survey should begin in the X1 position. If the needle pegs to the top of the scale, then switch the unit into X10 position. This should back the needle down, at which point the readings on the scale are the reading X 10. If the needle is still pegged to the top of the scale in the X10 position, then move the switch into the X100 position. At this point, all of the readings on the meter would be the reading X 100

If an alarm is enabled and Latch is not checked, the alarm will turn on when the level is exceeded and turn off again when the radiation level dips below the alarm level. If Latch *is* checked, the alarm will stay on once the level is triggered even if the radiation level dips below the alarm level. The only way to reset the alarm in that case is to uncheck Latch (when the radiation level is below the alarm setting) or to uncheck the alarm itself.

There are two types of swipes that are for use with the GammaPAL; Air swipes and Wipes for surfaces. The GammaPAL includes wipes for surface testing and are able to be used with The Ranger and Wipe Test Plate (included with The GammaPAL) for quantification or for use with the GammaPAL sampling matrix for qualification and identification. Additional Test Swipes Available Air Swipes are commonly found in an air pump line and are not included in The GammaPAL. They are a typically a small filter that collects the contents of the air passing through it. Most air filters will be able to determine the flow rate. So, for example, you can take a 1 liter sample of air with a fair degree of precision and use the filter to detect potential contaminants in the air via the filter based on a known volume.
