CALIBRATION (Cont.)
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 cal-
ibration data. Calibration should be performed as necessary to en-
sure accurate weighing. Masses required to perform the procedures
are listed in the following table.

Calibration masses are available as accessories.
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 cali-
bration 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 dis-
played, 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.
CARE AND MAINTENANCE
To keep the balance operating properly, keep the housing and plat-
form clean. If necessary, a cloth dampened with a mild detergent
may be used. Keep calibration masses in a safe dry place.
