In Figure
The battery voltage number displayed is the terminal voltage of the battery. During a charging cycle, the voltage can be anywhere from 5.5 volts to 8.5 volts. After the battery reaches its full charge, the charging circuit switches to trickle charge mode with a corresponding terminal voltage of approximately 7 volts.
The unit will remain in this trickle charge mode as long as the instrument is attached to an AC line. When the instrument is operated with battery power, the voltage will read between 6.5 volts (battery fully charged) and 5.4 volts (low battery shutdown voltage).
2.4.5 Using the UNITS SELECT Button
Pressing the UNITS SELECT button displays the Units Select screen, see Figure
Figure 2-11. The Units Select Screen with Dose Measurement Units Selected
The Display Units Conversion Factor (DUCF) is displayed at the bottom of the Units Select screen. The 35360A TRACKER Display uses the DUCF to convert from the detector calibration units to the display units selected during the customization process (see Section 5).
