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.
