Service Manual Functional Verification 31
Battery Accuracy Test
When a voltage of 6.2 ± 0.05 VDC is supplied to the unit battery terminals, and the AC is
disconnected from the unit, the unit reports a “Normal to High” voltage.
When a voltage of 5.45 ± 0.05VDC is supplied to the unit battery terminals, and the AC is
disconnected from the unit, the unit reports a “critically low” voltage.
1. Unplug unit from line power.
2. Connect a DC power supply in place of the battery.
3. Adjust power supply to 6.2VDC.
4. Turn the unit on, and then verify the unit does not indicate a low or critically low
battery.
5. Adjust power supply to 5.45 VDC.
6. Verify the unit indicates a critically low power and will shut down.
Sleep/Standby Mode Current Test
When the unit is powered on and the AC is disconnected, and the unit is in low power
standby mode, the unit’s current is:
1. Unplug the unit from line power and adjust the power supply to 6.4V DC ± .05.
2. Connect the DVM in series with the positive battery connection from the power
supply.
3. Press the on/standby button.
4. Verify the LCD turns off and that the current draw is less than indicated for the unit.
5. Disconnect the power supply.
Charger Detect Test
1. Connect a DVM to the battery harness while observing correct polarity.
2. Plug the unit into the AC power, and power ON.
3. Choose Main Menu > Systems Setting > Device info > Service Info > Service
Tests>PPPTEST2.EXE.See “Service Tests” on page 25.
Note
The unit may have a 5 to 10 second delayed response.
CP 100 Current CP 200 Current
< 5 mA < 5 mA
Note
There may be up to a 10 sec delay in the drop of current due to the progressive
hibernation mode.
