Span Calibration
1. With the balance turned ON, press and hold >O/T< until CAL
is displayed.
2. Release >O/T< , -C- is 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 cali-
brated and returns to the weighing mode.
5. Remove the calibration masses from the pan.

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 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.
1 N/C
2 Data Out (TXD)
3 Data In (RXD)
4 N/C

SYMPTOM
No Display.
Incorrect weight
reading.
Calibration proce-
dure does not
work.
Unable to display
weight in a particu-
lar weighing unit.
Balance won't
store selections
made in menu.
PROBABLE CAUSE
Power Adapter not
connected.
Balance out of cali-
bration.
Balance was not
rezeroed before
weighing.
Incorrect calibration
masses being used.
Weighing unit not ac-
tivated in menu.
END selection was
not used to exit
menu.
REMEDY
Connect AC Adapter.
Calibrate the bal-
ance.
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.
