Exposure and rate measurements made with external ion chambers are calculated using the stored
calibration factor (R/nC or Gy/nC) for the selected external chamber and air density correction. For more
information about entry of air density information (temperature and pressure), see SETUP mode.
2.5.9 Setup Mode
The Setup Mode is used to setup various features of the NERO mAx. From the setup screen the user
can do the following:
• Set the instruments internal real time clock.
• Set the temperature and pressure used in air density correction of exposure measurements.

MODE SELECT HOURS MINUTES SECONDS
Using the mode key, go to the SETUP screen and use the select softkey (1) to select TIME. When time is
selected, the time selection blinks and a highlight (reverse video) will extend across the other 3 display
fields. The hours, minutes and seconds keys select and increment hours, minutes or seconds. Holding
down any of these keys (hours, mins, secs) will continuously increment the selected unit. Once a unit of
time is selected, it may also be incremented or decremented with the up or down keys. Once the desired
time has been set, press the ENTER key to accept it.
The NERO mAx keeps time in a military or 24 hour format. As a result, the time must be entered in the
same 24-hour format. For example 9:30 AM is entered as 9:30 but 9:30 PM must be entered as 21:30.
