Operator Manual Rev 1.21
003X-607-121 Page 5
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.

Operator Manual Rev 1.21
Page 6 003X-607-121
Key Description
ZERO: The <ZERO> key is used to perform a
Zero adjustment on the scale display when an
empty scale has drifted away from a true zero
reading.
•The Zero adjustment is stored when power is
removed and is re-used when next powered
up.
•Long Press: When the indicator is set to
Industrial mode a long press of the <ZERO>
key will remove any stored zero adjustment.
TARE: The <TARE> key is used to temporarily
set the scale to zero (such as cancelling the
weight of a carton before performing a filling
operation). The display will show the Net weight
and the Net annunciator will be lit.
•The <TARE> key can operate in all modes
(ie. Industrial, OIML and NTEP).
•The weight tared is deducted from the allowable
range of the scale, reducing the maximum
weight that can be displayed.
•The Tare adjustment is stored when power is
removed and is re-used when next powered
up.
GROSS/NET: The <GROSS/NET> key toggles
the weight display between the Gross weight and
the Net weight (provided that a Tare has
previously been acquired using the <TARE> key).

Operator Manual Rev 1.21
003X-607-121 Page 7
Key Description
PRINT: The <PRINT> key will trigger an output of
the current weight reading if a printer or computer
has been attached to the instrument and the
manual print function has been selected.
•The PRINT prompt is displayed while waiting
for the printer to accept data.
•If the printer is offline the PRINT prompt will
remain for a maximum of 10 seconds before
the operation is cancelled.
•Each weight printed is automatically added to
an internal total weight. Note: For K307,
accumulation mode must be enabled for this to
occur.
•Long Press: A long press of the <PRINT> key
will print the total. The total weight is then
cleared automatically.
FUNCTION: The <FUNCTION> key is program–
mable to suit customer requirements. A label
identifying the special function will be attached.
Refer to Special Function page 10 for details of
the available functions.
•Long Press: A long press of the <FUNCTION>
key may be used for certain functions
depending on the primary function of the key.
3.3. Stability Considerations
Once a <ZERO>, <TARE> or <PRINT> key is pressed the
unit waits for a stable valid reading before performing the
associated operation. If the weight readings remain
unstable or invalid due to some diagnostic error for longer
than 10 seconds, the operation is cancelled and the
STABLE ERROR message is displayed.
