General Operation

This section describes power up, power usage and general operation.
3.1 Power Considerations
The 780 has a rocker style power switch on the back panel. Refer to the photo below.
The 780 is a portable battery powered test instrument. It is equipped with nickel metal hydride batteries. Typically, you
can use the 780 on batteries for about 4 hours. 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 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 with the charger and only use the batteries 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.

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 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 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.
