OPERATION

Check USB Charger Voltage

Plug the USB200 into the charger port and read
the voltage (V). If the voltage is outside the
normal 5V (±5%) USB charging range, ‘H’ will

appear (>5.3V) or ‘L’ will appear (< 4.70V).

Check Capacity on Electronic Devices

Plug the USB200 into the charger, connect a
cable to the USB200 input jack, and connect an
electronic device to the cable. Read the current
draw in Amps (A) and transfer capacity in milli­amp hours (mAh).

Compare Charging Cables

Use the same test setup as described in ‘Check
Capacity…’ and compare cables. Read the
displayed current (A) for each cable. Higher
current = better quality cable.

Record Memory for Charge Capacity

The USB200 records charge capacity over time in
mAh units. Insert the USB200 into a charging
port and short press the M button to select a
storage bank (0-9). Recording begins
automatically. To erase data in the selected
bank, long press the CLR button.
