To modify alarm settings, highlight “MODIFY SETTINGS” from the “ALARM SUB-MENU;” then press
“SEL.” The screen will now display the “ALARM UNIT SUB-MENU,” as in Figure 2-27. Highlight the
desired unit using the “UP” or “DOWN arrow key, then press “SEL.” The “ALARM LEVEL SETUP” screen
will now be displayed as in Figure 2-28. The level may be modified by using the “UP” or “DOWN” arrow
key. Once the desired value is reached, press “SEL” to permanently save it. To enable (or disable) the
alarm, simply highlight that selection from
the “ALARM SUB-MENU,” then press
“SEL.”
NOTE
If the user attempts to set the alarm level to a value
higher than the “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.

2.3 Operating Modes
The instrument operates in three separate modes: Rate, Integrate, and Scaler. In the Integrate and Scaler
modes, pressing the “START/STOP/RST/SAVE” key will start the operation if none is currently in
progress. Conversely, it will stop the operation if one is currently in progress. When the instrument is in
the “INTEGRATE” mode, the “Readout” area on the normal operating display will show the integrating
result and the corresponding units of measure. The “UNITS” area will display the accumulated time and
its corresponding units (seconds).
