Power Considerations

The 780/780AH has a rocker style power switch on the back panel. Refer to the photo below.
The 780/780AH is a portable battery powered test instrument. It is equipped with nickel metal hydride batteries.
It requires an overnight charge. Quantum Data recommends that you set the screen brightness to the minimum
level required. Turn the unit off if you are not going to be using it for extended periods.
The 780/780AH is supplied with the Part No 25-00094 12V DC power supply and charger as well as a part
number 30A00400A03 line cord. We recommend that you use the 780/780AH with the charger and only
use the batteries when fully charged for a short period of time—an hour or two—when power is not
available.
Important Notes about power usage and status:
Monitor the battery meter on the lower right.

The screen will automatically dim after 2 minutes of inactivity to save on battery life.

The 780/780AH will begin to chirp when it requires recharge. Turn the unit off or plug it in to the wall

charger when you hear the chirp.
A green indication or partial green indication shows the battery is being charged.

A gold color indicates that the device is being powered through the wall charger.

Fully charge the 780/780AH overnight.

You must touch an active portion of the LCD to update the battery indicator to show its power status.

Do not continue using the 780/780AH from battery power when the battery meter indicates that the

batteries are exhausted. When you see a thin green line at the right most portion of the battery icon,
turn the power off and switch to line power using the AC Charger adapter; then reapply power.
