Operational display ranges are dependent on the detector and dead time configuration. The minimum and maximum display can be set to limit the display to the calibrated range.

Linearity: Readings within 10% of true value

Data Logging: Can store up to 1000 data points internally. Requires Lumic Data Logger Kit, see Options.

Response Time: User-selectable from 1 to 60 seconds, or auto-response rate FAST or SLOW
