In Case The Zone Of Use Is Different From The Calibration Zone One Should - Vetek DGT Technical Manual

If one does not want to carry out the equalization proceed with point 11).
Cell Equalization procedure:
5) Select the "EquAL" step and press ENTER/PRINT: the display shows "rESEt?"; confirm with ENTER to
clear the present equalization and proceed to the equalization of the cells; by pressing C one exits the
equalization.
6) Select "Eq 0" step (equalization of zero): unload the weighing system and press the PRINT key.
7) Select "Eq 1" step (equalization of the first cell): put a calibration weight on the cell connected to input
1 of the indicator and press the PRINT key.
8) Select "Eq 2" step (equalization of the second cell): put the same calibration weight on the cell
connected to input 2 of the indicator and press the PRINT key.
9) If nChan > 2:
Select "Eq 3" step (equalization of the third cell): put the same calibration weight on the cell
connected to input 3 of the indicator and press the PRINT key.
If nChan > 3: Select "Eq 4" step (equalization of the fourth cell): put the same calibration weight on
the cell connected to input 4 of the indicator and press the PRINT key.
10) When the equalization is finished the message 'EQ OK' appears and one exits the equalization
submenu.
11) Select the "ntP" step and press PRINT.
12) Nr. of Calibration points
Set the number of points with the ZERO or TARE keys on which one wants to make the calibration (from 1 to
3, with 1 one will make the zero point and a weight point) and press PRINT.
13) Acquisition of Scale Zero
Select the "tP0" step (scale zero point): unload the scale and wait a few seconds; then press PRINT: if the
equalization of the channels has not been made the 'no Eq?' message appears and the instrument emits an
acoustic signal: press the ENTER/PRINT key to proceed anyways with the acquisition of the weight or the C
- ON/OFF key to exit the step.
14) Repeat the points from 14) to 17) described previously in the "'SCALE CONNECTED TO JUST ONE
CHANNEL' MODE".
15) Saving the Calibration
When the calibration has been made of all the necessary points, press various times the C - ON/OFF key
until the indicator shows "SAVE? in the display: confirm with PRINT to store and return to weighing.
Note: after the cell equalization, is necessary to execute the calibration procedure
4.3 IN CASE THE ZONE OF USE IS DIFFERENT FROM THE CALIBRATION ZONE ONE
SHOULD:
1) Enter the SET-UP ENVIRONMENT of the scale (when turned on, press for an instant the TARE key while
the firmware version is displayed ).
2) Enter the step SEtuP >> ConFiG >> GrAV and set the gravity acceleration value for the CALIBRATION
ZONE.
3) Make the calibration as described previously.
4) Save and exit the SET-UP ENVIRONMENT (press various times the C - ON/OFF key until the indicator
shows "SAVE?" in the display and confirm with PRINT.
5) Enter the SET-UP ENVIRONMENT of the scale and enter the step SEtuP >> ConFiG >> GrAV and set the
gravity acceleration value for the ZONE OF USER.
6) Save and exit from the SET-UP ENVIRONMENT.
7) The weight error caused by a different gravitational value between the calibration zone and the zone of use
is automatically corrected.
NOTE: with Approved Instrument, upon start-up the display shows the gravitational acceleration value of the
ZONE OF USE.
