Calibration check using the external weight
E.TEST
1
Press in the weighing mode.
(the weight symbol) will light up and the
value of the weight that should be placed on the
pan will ash.
*
If "WAIT" is displayed…
The calibration record is being output.
When output has nished, span
calibration will start automatically.
*
If "BUSY" is displayed…
There is something placed on the pan.
Take the item off the pan and follow the
procedure below.
To cancel calibration check, press
( with the TXB series).
*
If no operation is performed within
60 seconds…
"ERR C" (calibration error) is displayed.
Press ( with the TXB series)
and repeat the operation from the
beginning.
2
Enter the calibration weight value.
If necessary change the weight value displayed
to match the weight that will be used for
calibration. If there is no need to change it,
proceed to step
3
.
(Enter a weight value if necessary.)

"Entering Numerical Values", page 49
For details on the range of weight values that
can be used, see "Specications" (^ page
145).
3
Place the calibration weight on the
pan.
Wait until the ashing weight value display
changes to a ashing zero.

With models that feature the
windbreak...
After placing a weight on the pan or
removing a weight from the pan, check
that the glass door is fully shut.
*
If "ERR C" is displayed…
Calibration check has failed for one of
the reasons given below.
There is too large a discrepancy
between the zero point of the
balance and the sensitivity.
A container has been placed on the
pan.
The pan is not on the balance.
The wrong weight has been placed
on the pan.
No operation has been performed
within 60 seconds of the ashing
weight value or zero display.
Press ( with the TXB series)
and repeat the operation from the
beginning.

Take the calibration weight off the
pan.
The sensitivity drift is displayed.
*
If there is no need to change the
sensitivity drift…
On pressing ( with the TXB
series) "ABORT" is displayed and
calibration check ends.
5
Press
"END" will be displayed. The sensitivity drift
is adjusted and the balance will return to the
weighing mode.
What is sensitivity drift?
The sensitivity drift is the amount by which the balance weight reading is off the true value when a
weight close to the weighing capacity is placed on the pan.
For example, with the TX323L (weighing capacity of 320 g, minimum display digit of 0.001 g), if a
300 g weight is placed on the pan after a drift of "-0.005 g" has been indicated, the weight reading will
be "299.995 g".
To correct sensitivity drift by adjustment, perform "span calibration" (^ page 56).
