Ac Operation - ADInstruments AD3A02 User Manual

4.2 AC operation

If the instrument is mainly used at one location, e.g. in a laboratory or test department, the AC adapter
can be used to power it instead of batteries. There is a DC input jack on the left side of the AD3A02
instrument casing into which the output cable of the AC adapter is plugged. And when the AC adapter is
plugged in, the AC Indicator on the LCD will be displayed.
Note:
1 Power is supplied by the AC adapter even if battery is fitted. And the battery indicator is not displayed
on the screen when AC adapter is plugged.
2 Make sure that the operating voltage of the AC Adapter / Charger is the same as the local AC line
voltage.
