CHAPTER 3 SCALE TESTING AND CALIBRATION
3.5.2 Battery Tests (cont.)
3. With the AC Adapter connected, measure the battery voltage at the battery terminals; the voltage
should be approximately 6 to 7 Volts dc when charging. The voltage should be above 6.0 Volts
dc ten minutes after charging stops.
NOTE : If the scale operates less than 80 hours, charge the battery and turn on the scale and test
how long the scale operates. If the scale operates less than 40 hours with no backlight, the battery
should be replaced. This is 50% capacity.
4. If the battery requires replacement, refer to Section 4.6, charge the new battery overnight and
check scale performance.
