64 Operation and Maintenance Manual
Detector Front Panel Controls
As illustrated in Figure 21, the front panel is divided into three sections: signal
control, display output control, and power control. Each section is described
below. All the front panel LEDs are red in the ON mode and darkened in the
OFF mode except for POWER. This LED toggles green for ON and red for
STANDBY. In STANDBY mode, the front panel display and high voltage to the
photomultiplier tube (PMT) are turned off. The red LED in the STANDBY mode
serves as a reminder that power is still supplied to the instrument.
