3.2. Operation Keys
Key Description
POWER: The <POWER> key is used to turn the
instrument on and off.
• To initially turn the instrument ON: Press
and hold the <POWER> key until the display
starts up.
• To turn the instrument OFF: Press and hold
the <POWER> key for three seconds. The
instrument will display OFF followed by the
three-second countdown.
Note: If the <POWER> key has been locked,
the instrument cannot be turned off from the
front keypad.
• Battery Operation: When using batteries the
backlight may automatically turn off to
conserve power after a short period of
inactivity. Motion on the scale or a short press
of the <POWER> key will turn the backlight on
again.
• Automatic Operation: The <POWER> key
has a memory function associated with it. This
means that the state of the power setting is
remembered even if external power is
interrupted. It is therefore possible to turn the
instrument on in the safe knowledge that it will
operate whenever external power is available
and will not need to be manually turned on
again if the power is interrupted.
