To keep the balance operating properly, keep the housing
and platform clean. If necessary, a cloth dampened with a
mild detergent may be used. Keep calibration masses in a
safe dry place.

Masses must meet or exceed ASTM Class 1 Tolerance.
Calibration masses are available as accessories.
Calibration Masses
Before beginning calibration, make sure masses are available.
If you begin calibration and realize calibration masses are
not available, exit the procedure by pressing and holding Mode
Off until balance returns to weigh mode. The balance will
retain previously stored calibration data. Calibration should
be performed as necessary to ensure accurate weighing.
Masses required to perform the procedures are listed in the
following table.
Span Calibration
1. With the balance turned ON, press and hold >O/T< until
CAL is displayed.
2. Release >O/T<, -C- momentarily displayed followed by the
value of the calibration mass which is to be placed on the
pan.
Do not disturb the balance when -C- is displayed.
Incorrect calibration may result.
3. Place the indicated span calibration mass on the pan.
4. Press >O/T<, -C- is momentarily displayed, then the weight
of the mass on the pan is displayed.
5. Remove the calibration mass from the pan. The balance is
now calibrated and returns to the weighing mode.
Linearity Calibration
1. With the balance OFF, press and hold >O/T< until MENU
is displayed, then release it and UNITS is displayed. Press
Mode Off, LIN is displayed.
2. Press >O/T<, -C- is displayed followed by the value of the
first mass which must be placed on the pan.
3. Place the required mass on the pan and momentarily press
>O/T<, -C- is displayed followed by the value of the next
mass to be placed on the pan.
Do not disturb the balance while -C- is displayed.
4. Place the second required mass on the pan and
momentarily press >O/T<, -C- is displayed. When the
weight on the pan is displayed with the stability indicator,
the balance is calibrated and returns to the weighing mode.
5. Remove the calibration masses from the pan.

SYMPTOM
No Display.
Incorrect weight
reading.
Calibration procedure
does not work.
Unable to display
weight in a particular
weighing unit.
Balance won't store
selections made in
menu.
PROBABLE CAUSE
Power Adapter not
connected.
Balance out of
calibration.
Balance was not
rezeroed before
weighing.
Incorrect calibration
masses being used.
Weighing unit not
activated in menu.
END selection was not
used to exit menu.
REMEDY
Connect AC Adapter.
Calibrate the balance.
Press >O/T< with no
weight on the pan,
then weigh item.
Use correct masses.
Use Units menu to set
desired units ON (see
menu).
You must use END to
exit each menu and
save selections.
TROUBLESHOOTING
