Possible average count settings*1
*1. The response speed of the linear output is calculated as the measurement period
× (average count setting + 1) (with fixed sensitivity).
The response speed of the judgement outputs is calculated as the measurement period
× (average count setting + 1) (with fixed sensitivity).
