Power

The POWER button toggles the system power on or off.

Test/Detector

The TEST/DETECTOR button displays and sequences the Test/Detector screens.

Units Select

The UNITS SELECT button displays the Units Select screen. Subsequent presses toggle the measurement units between dose and dose rate units.

Air Density

The AIR DENSITY button displays the Air Density screen. Subsequent presses advance the cursor through the temperature, pressure, and Air Density Correction Factor (ADCF) fields.

Gain Select

The GAIN SELECT button displays the Gain Select screen. Holding the GAIN SELECT key for three seconds toggles the 35360A TRACKER Display between the Gain Setting and Normal Operation modes. In the Gain Setting Mode, pressing the GAIN SELECT button advances the cursor through the Front Panel Gain Factor (FPGF) fields.

Measure Select

The MEASURE SELECT button displays the Measurement screen. Subsequent presses toggle the display mode between absolute and percentage presentations.

Reset

The RESET button zeroes all measurement readings when dose units are selected. This button displays the Measurement screen if it is not already displayed.

Up

The UP button function depends on the displayed screen. It increments the temperature, pressure, or a front panel gain. It toggles the state of the air density correction annunciator or the front panel gain annunciator. For the Test/Detector screen or the Measurement screen, it displays the previously displayed screen.

Down

The DOWN button function depends on the displayed screen. It decrements the temperature, pressure, or a front panel gain. It toggles the state of the air density correction annunciator or the front panel gain annunciator. For the Test/Detector screen or the Measurement screen, it displays the next screen.
