7.
Reduce the voltage of the power supply until Voltmeter reads 20.0V, then long press START
on the 9015607 ONLY port. The UUT should read CHARGING. The ammeter should read
220mA or greater. The current displayed on screen should match the ammeter within
±10mA. Long press START on the 9015607 ONLY port. The voltage displayed on screen
should match the voltmeter within ±0.4V.
8.
Increase the voltage of the power supply to 22.0V. The UUT should display FLOAT.
Voltmeter should read 22.0V ±0.4V, and ammeter should read -3mA ±1mA.
9.
Move the test setup to the right side port labeled 9015607/9016925 with Battery Type switch
selecting the 9015607 battery. Adjust power supply to 22.0V.
10.
Reduce the voltage of the power supply until Voltmeter reads 20.0V, then long press START
on the 9015607/9016925 port. The UUT should display CHARGING. The ammeter should
read 220mA or greater. The current on screen should match the ammeter within ±10mA.
Long press START on the 9015607/9016925 port. The voltage displayed on UUT should
match the voltmeter within ±0.4V.
11.
Increase the voltage of the power supply to 22.0V. The UUT should display FLOAT.
Voltmeter should read 22.0V ±0.4V, and ammeter should read -3mA ±1mA.
12.
Set Battery Type switch to the 9016925 position. Reduce the voltage of the power supply
until Voltmeter reads 20.0V. Long press START on the 9015607/9016925 port. The UUT
should display CHARGING. The ammeter should read 450mA or greater.
13.
Long press START on the 9015607/9016925 port. Increase the power supply to 22.0V. The
UUT should read FLOAT. UUT voltage should display 22.0V ±0.4V and ammeter should read
-3 mA ±1 mA.
14.
Turn off power supply and the UUT.
15.
Connect test setup per Figure 2:
