Rate screen #2 shows the display format during a rate measurement. When the signal from the active
diode(s) indicates the beginning of an exposure, the VeriDose V will start the exposure timer and continue
to acquire data.
The instantaneous rate for each channel is displayed as the exposure is occurring. The cumulative dose
for each channel is measured in the background and although not displayed can be printed on reports.
Any channels that exceed the dose set-point of an active alarm will flash (see MEASURE - ALARMS).
Pressing the DONE soft-key will conclude the measurement and stop the exposure timer. The accumu-
lated dose and "PRESS ANY KEY TO CONTINUE MESSAGE" will be displayed. Pressing the ABORT
soft-key will display a message box that allows the user to continue the exposure by pressing NO or to
return to the MENU display by pressing YES.
If VeriDose V is in A-PRINT (auto-print) mode the message “PREPARING REPORT...PLEASE WAIT” will
appear as the selected report is printed after each exposure (see SETUP - PRINTER). The reports
printed following a rate mode measurement will include the dose values only.

The Alarm screen permits alarm levels to be set and enabled or disabled for any given exposure by
individual channel. Alarm levels and status settings apply to all groups. Pressing the soft-key under the

UP and DOWN keys changes the number. Pressing the STATUS column will toggle the highlighted
STATUS ON/OFF. Pressing the MODE soft-key or OPTION soft-key will exit this screen with the
highlighted items selected. All menu selections are maintained in non-volatile memory and will be
maintained when the power to the instrument is turned off. The default from the factory is alarm channel
STATUS OFF.
