the optional adapter to power the unit.
Short press the power button. The display will switch on.
Refer to Section 3.2 for display details.
Configure the 42280A using a PC (recommended) or the front-panel keypad. See Section

Once programmed, long press the START/STOP button to
start logging readings. The green recording LED and the
REC display icon flashes while logging. The logger will not
start if it has not been configured.
