9.10 “SCREEN SAVER” FUNCTION (OPTIONAL OR INCLUDED DEPENDING ON THE MODEL)
If the indicator is fitted with the date/time function (optional or included depending on the model), it is possible to enable the
“Screen Saver”: after a programmable time (from 1 to 255 minutes) with the scale unloaded, the time is shown on the
display, in the “HH:MM:SS” format and the clock symbol ( ) is enabled. As soon as a weight variation is detected, or a
key is pressed, the indicator returns to view the current weight.
To set the function:
- Turn on the scale, press the TARE key while the firmware version is displayed (the display shows the “tyPE” menu).
- Press ZERO many times (to scroll ahead through the parameters) or TARE (to scroll backwards) until one finds the
“F.ModE” parameter.
- Press ENTER/PRINT to enter the menu.
- Scroll to find the “SCr.SAV” parameter and select it.
- With the ZERO or TARE key select the possible options: “no” (disabled), “yES” (enabled).
- Confirm with ENTER/PRINT; if one has selected “yES”, one is asked to enter the number of minutes after which the
indicator should show the time: enter a number between 1 and 255 (using the MODE key to select the digit to be
modified and the ZERO/TARE keys to decrease/increase it) and confirm with ENTER/PRINT.
- Press the C key many times until the display shows the message “SAVE?”.
- Press ENTER/PRINT to confirm the changes made or another key to not save.
NOTE: the “SCr.SAV” parameter is shown if there is the date/time option.
9.11 KEYBOARD LOCK
It is possible to disable the keyboard functions in order to avoid accidental pressing of the keys.
The keyboard can be disabled/enabled by setting the corresponding parameter in the F.ModE >> LCk.kEy step of the
setup environment (TECH.MAN.REF.); if the “on” parameter is selected in the this step, after 15 seconds of keyboard
inactivity in the weighing phase, the keyboard is locked (the “LoC.kEy” message is displayed).
In this case it’s only possible to turn off the instrument by pressing the C key for about 10 seconds, and turn on the
instrument.
By pressing the ZERO and ENTER/PRINT keys in succession, the keyboard is unlocked (the “unL.kEy” message is
displayed). If instead a different key is pressed, the message “PrESS ZEro to unLoCk” is displayed; when the ZERO key is
pressed, the message “noW PrESS Print to unLoCk” is displayed.
NOTE: The keyboard may be disabled also by closing an input, if programmed, of the optional expansion board: refer to the
“inPutS" parameter of the set-up environment (TECH.MAN.REF.); in this case however when the keys are enabled or
disabled, the message “LoCkEd” does not appear on the display and upon pressing a key the display shows “LoCkin” for an
instant.
9.12 PRINTING
If a printer is connected, it is possible to print the programmed weight data, for example:
- 4 heading lines of 24 characters
- GROSS weight
- TARE weight
- NET weight
- ticket number
- date and time (optional or included depending on the model)
- a CODE 39 bar code (both with the LP542PLUS labeller as well as the TPR thermal printer).
Besides the generic printing described above, each single functioning mode will have some specific printouts, which are
described in the operating mode.
It is also possible to send weigh data to the PC, with standard or extended string, via the printer port (ALL.Std/ALL.EXt or
PrPC.Std/PrPC.EXt in “Pr.ModE” parameter).
Executing printouts with NON approved scales.
In order to print with non approved scales the following conditions must exist:
- the weight must be stable;
- the gross weight must be >= 0;
- the printout is always active.
