2.2 Power Failure
If a power failure occurs during an Automatic Count, the processing of the samples is
interrupted. An internal battery provides back-up of the system memory. When power is
restored, operation is automatically resumed. A message
“POWERFAIL RECOVERY” and the
date and time are printed to indicate the occurrence of a powerfail.
2.3 Operating Controls
On the front of the instrument are two groupings of controls:
the alpha-numeric keyboard for making letter and number entries; and the operator control
keypad for controlling the instrument and for program editing. See Figure 2.3.
Alpha-numeric Keyboard
The keyboard is used for entering information when setting up a user program, a new isotope,
or a dpm quench curve (if dpm is installed). The basic design is similar to the computer
terminal keyboard. All entries are made in upper case (capital letters). The numeral keys are
used for numbers only. There are separate keys for these symbols: # + - , . :.
