Chapter 3. Using Your ATS

Using the Rechargeable Battery
The teaching wafer operates from an internal rechargeable battery. From a full charge, the
battery provides about two hours of continuous use. Before using your teaching wafer for the
first time, charge it for two hours.
The battery can be recharged about 500 times before the charge life starts to degrade
significantly. The battery is not user replaceable. For information on replacing the battery, see
“Annual Factory Calibration and Battery Replacement,” on page 5.2
Battery performance degrades at temperatures outside the optimum operating temperature
range: 20 °C - 50 °C.
Monitoring the Battery Level
TeachView receives frequent updates from the teaching wafer on the state of the teaching
wafer’s battery. The
Battery
indicator in the
ATS wafer status
area of the TeachView window
shows the approximate percentage of operating time remaining before you must charge the
battery.

Charging the Battery
To charge the teaching wafer’s battery:
1. Use only the battery charger supplied with your gapping wafer. Using a different battery
charger might damage your gapping wafer or create a safety hazard.
2. Do not charge the gapping wafer if its internal temperature is higher than 45 °C. Charging
the gapping wafer at a temperature higher than 45 °C might damage your gapping wafer
or create a safety hazard.
3. Place the teaching wafer in the charging clean box. Rotate the wafer until the WaferSense
ATS logo is right side up and approximately level when the hinged edge of the box is
away from you. Close the lid.
