1 The Accu-Pro measures the background zero when you select a dose mode. If high sensitivity is set to
off, the system will make a quick coarse zero measurement. Some fluctuations will be observed in dose
rate mode and dose accumulate may exhibit drifting. If high sensitivity is set to on, the system will make
a fine zero measurement which takes 3 to 5 seconds. The dose rate will fluctuate much less and the
dose accumulate drift will be greatly reduced. It is recommended that high sensitivity mode is enabled for
most dose measurements.
