Calibration Procedure For Dependent Channels Mode (Could Eventually Be Digitally Equalized) - Vetek DGT Technical Manual

from 3) >> 16).
20) Saving the Calibration
Once the calibration has been made of all the necessary points, press many times the C - ON/OFF key until
the indicator shows "SAVE? in the display: confirm with PRINT to store and return to weighing.
N.B.: the calibration points must be in increasing order (point 1 < point 2 < point 3).
4.2 Calibration procedure for DEPENDENT CHANNELS MODE (could eventually be digitally
equalized)
Premise: this procedure is to be followed in case one has to calibrate a scale having 2, 3 or 4 load cells in the
"DEP.CH" functioning mode, (see section. 3.2: tYPE –Application type) and wants to equalize directly from the
indicator, without using the external junction boxes.
In this case one should connect each single cell to one of the available channels of the instrument.
Note: it is always better to carry out the equalization procedure (steps from 4 to 9), but it isn't compulsory (in some
applications, it can not be done).
SETUP
ENVIRONMENT
(§) = indicates that the parameter is visible only in certain programming conditions; see the explanation of the parameter itself for
the details.
(*) = indicates that with an approved instrument the parameter can be not visible or read only; see the explanation of the
parameter itself for the details.
1) Enter in the SET-UP ENVIRONMENT of the indicator (when turned on, press for an instant the TARE key
while the firmware version).
2) Select the type of application:
Enter in the "tyPE" step and select the "dEP.Ch" parameter.
3) Select the number of connected cells
Select the number of cells (in other words, the number of the channels, from 2 to 4) in the SEtuP >>
ConFiG >> nChan step and press ENTER/PRINT.
4) Repeat the passages from 4) to 10) described previously in section 4.1 "Calibration procedure for
INDEPENDENT CHANNELS' mode"
