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.
