Calibration - Precise Instrument DAT 400 Technical Manual

The calibration described herein should be performed with the use of sample weights and/or product
pre-weighed on a weighing system.
Before proceeding with the calibration of the full scale, always perform the zero calibration.
During the calibration phase, the display shows the weight intermittently with the inscription CaL.
ATTENTION: At switching off the instrument without exiting the set-up menu, the programming executed
is not stored.
NOTE In the event that after calibration, the system shows linearity errors, you should verify that the
weighed structure is completely free of mechanical constraints.
ZERO CALIBRATION
Perform the operation when the scale has no items (including the
fixed tare), and when the weight is stable. The zero of the system is
done by pressing the key 0.
The weight displayed resets and the display shows Cal alternated
by 0. You can repeat this operation more times.
CALIBRATION OF FULL SCALE
Prior calibration load the sample weight on the system and wait for
the stabilization; the display shows a weight value.
Press the SET key to adjust the weight. The display shows the theo-
retical weight value with the first digit to the left flashing. With the
arrow keys, enter the actual weight loaded on the system starting
from the first flashing digit. Switch to the next digit by pressing 0.
The confirmation of the last digit (far right) with the PRG key corrects
the weight. The display shows CAL, by altering the actual weight
value entered.
If the set value is higher than the resolution offered by the instrument,
the weight is not accepted and the display shows an error message
for a few seconds.
This procedure can be repeated.
Press the PRG key again to return to the CaLIb. menu.
EXIT FROM CALIBRATION MENU
The exit from the menu CaLIb is performed by pressing the
key until the appearance of the message store?.
To store the new calibration and exit the setup menu, press the PRG
key.
To cancel the calibration of zero and full scale:
FUN +0 it cancels the zero calibration.
FUN + SET it cancels the calibration of the full scale.
