entered, the instrument emits a prolonged sound, after which it zeros the value just entered.
Ao ZEr
By entering this step, one sets the analogue output value when the scale displays zero weight (supplied when the
scale is in under load). This value can be anywhere between 0 and 65535 (values of the digital/analogue converter);
if a higher digit is entered, the instrument emits a prolonged sound, after which it zeros the value just entered.
Ao Min
By entering this step, one sets the minimum value of the analogue output, in other words:
-
with functioning on the positive weight the value corresponding to the under load condition.
-
with functioning on the negative weight the value corresponding to the full scale value of the scale and the
over load condition.
This value can be anywhere between 0 and 65535 (values of the digital/analogue converter); if a higher digit is
entered, the instrument emits a prolonged sound, after which it zeros the value just entered.
SiGn
By entering this step, one sets the functioning on the negative or positive weight.
Note:
It’s not possible to set the functioning on the negative gross weight; for this purpose the parameter is
displayable only in the functioning on the net weight.

8. PROGRAMMING THE PRINTOUTS
If in the set-up environment the presence of the printer has been configured correctly, the indicator carries out the
print functions; each functioning mode has specific printouts, shown in the "Print examples" section in the user
manual
(USER MAN.REF.) . In any case, it is possible to define some printing fields, the size of the characters, a
heading and other options depending on the printer and the predefined functioning mode.
In the "Pr.Mode" step of the set-up environment it is possible to select whether to print on the DP190 / TPR printer or
the LP542S (LP542P) labeller; see the following steps for all the printing options.
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) Select the SEtuP >> SEriAL >> Com.Prn >> PrMode step and press PRINT .
3) Select the desired printer ("tPR" or "LP542P) and press PRINT .
4) In the section 3 "SET-UP ENVIRONMENT" see the descriptions of the "baud.Pr", "Bit.Pr", "PWr.Prn",
"on.Prin" and "Prn.CtS" steps for configuring the baud rate, the number of transmission bits, the printer’s
power supply and the CTS signal.
5) Select the " Pr Conf " step and press PRINT : one enters the PROGRAMMING MENU OF THE PRINTOUTS.
Below is the description of the steps.
6) Once the setting have been made, press the C - ON/OFF key various times until the indicator shows "SAVE?
In the display: confirm with PRINT to memorize and return to weighing.
