    “over-range” value, the alarm level will automatically default to the “over-range” value instead. Also, when the user sets an alarm value in units (other than “cpm”) the ASM-990, ASM-992, and ASM-993 automatically convert those units to the approximate “cpm” value. The conversion accuracy, in this case, is +/- 1% of the set point.

    Calibration Calibration Section 3 Calibration 3.1 Calibration Probe calibration parameters (probe profiles) are NOT operator accessible through the front panel. Rather, they will be downloaded, through the usage of PC based calibration software, via the IrDA port. Parameters for each calibrated probe are then stored/saved in the unit’s non-volatile memory (EEPROM). The user may then select from one of the previously stored probe data calibration parameters.
