standard setting on CAY series.) See 14. STANDARD SPAN
CALIBRATION (Sensitivity Adjustment).
(7) Zero appears on the display and blinks.
(8) The predetermined mass for the calibration weight is displayed and
blinks.
(9) Place the correct calibration weight on the pan.
(10) Zero appears on the display and blinks.
(11) Unload the weight.
(12) If the GLP/GMP corresponding output is ON, the calibration result
is output to an external unit.
(13) Span calibration is complete when
"CAL End"
is displayed for
several seconds and the display returns to mass display.

Span Check Using the Built-in Weight
The built in weight is only available on the CAW/CAX series balances.
Follow the procedure below to perform span check using the built-in weight.
Procedure
(1) Warm-up the balance.
F
See Section
3. “WARM-UP.”
(2) Verify that the balance is level.
(3) Verify that the balance pan is empty and press the
→
O/T
←
key to
zero the display.
(4) From the mass display, press the CAL/MENU key several times.
When
"Func.SEL"
is displayed, press the
→
O/T
←
key.
(5) Press the
→
O/T
←
key when
"CAL"
is displayed.
(6) Press the CAL/MENU key. When
"itESt"
is displayed, press the
→
O/T
←
key.
Span calibration starts at this point.
(7) When
"tESt 2"
is displayed, the balance verifies the zero point.
(8) When
"tEST 1"
is displayed, the built- in weight is automatically
placed on the pan inside the balance.
(9) When
"tESt 0"
is displayed, the balance verifies the zero point again.
(10) The deviation of sensitivity after previous span calibration is
displayed when this check is complete.
(11) If the GLP/GMP corresponding output is ON, the check result is
output to an external unit.
