*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).
*2. The output can be switched between a current output and voltage output using a switch on the bottom of the Amplifier Unit.
*3. Setting is possible via the monitor focus function.
*4. A Calculating Unit (ZX-CAL2) is required.
