1. INTRODUCTION
The purpose of this manual is to help the user get to know the weight indicator’s various functioning modes, the keys’
functions and the display indications. t is possible that one may incur into the phrase “TECH.MAN.REF.”: this means that
an advanced function is being described (therefore, for the technical personnel) and which is further explained in the
corresponding technical manual.
We advise to carefully follow the instructions for programming the weight indicator; by taking actions not
indicated this manual, one could cause the scale to not work properly.
n addition to having all the characteristics of a high precision scale, the indicator has the unit of measure / pounds
conversion function, the gross weight / net weight conversion, set point on gross weight or net weight, in/out weigh, single-
multiscale repeater, alibi memory, +/- tolerance check, sample weight percentage, freezing the weight on the display, peak
detector, weighs totaliser and piece counter.
The indicator adapts itself to normal weighing applications in either industrial settings, such as during factory production
processes, or that of commerce, such as legal for trade applications, also satisfying the frequently needed ability to transmit
and print the data through its two bidirectional serial ports.
This manual has been made as carefully and exactly as possible; in any case, your suggestions are always
welcome.
WARNING
Any attempt to repair or alter the unit can expose the user to the danger of electric shock and it will void our warranty. This
instrument is covered under warranty provided that IT HAS NOT BEEN OPENED BY THE USER for any reason. f any
problem with the unit or system has been experienced please notify the manufacturer or the dealer from which the
instrument was acquired.
With the 6V rechargeable battery option, it has to be completely recharged (12 hours) in the first installation of the
instrument; we RECOMMEND disconnecting the battery if the instrument is not going to be used for more than 30
days.
In order to avoid the deterioration of the rechargeable battery:
In standard conditions:
- never leave the battery partially or completely uncharged; at least once a week recharge it completely .
In case the instrument is not used for a long period, one needs to:
- completely recharge the battery before the system is switched off for the last time;
- recharge completely every 3 months.
Do not pour liquids on the indicator!
!!
!
Do not use solvents to clean the indicator!
!!
!
Do not expose instrument to either direct sun light or any heat sources!
!!
!
Always mount the indicator and platform in a vibration free setting!
!!
!
Read carefully & apply what described in the POWER SUPPLY & START-UP section!
Do not install in an environment with any risk of explosion!
!!
!
All the connections of the indicator have to be made respecting the rules applicable in the zone
and in the installing environment
Everything not expressly described in this manual has to be considered as improper use of the
equipment.

.3 DFWPM POWER SUPPLY
The instrument can be powered with 4 AA rechargeable or not rechargeable batteries which are in the extractable battery
box.
t is also possible to power the indicator with a 5 Vdc voltage supplied by the USB port connected to the PC (depending on
the indicator model).
NOTE: if the AA rechargeable batteries are used (not supplied), the recharge MUST be made separately using the
proper battery charger (not supplied).
TO INSERT OR REMOVE the AA batteries, pull out the battery box which is found on the upper side of the instrument
(chapter “ NSTALLAT ON”), remove the discharged batteries and insert the new ones according to the shown polarity, then
insert the battery box again.
TO POWER the instrument using USB-PC port, connect the USB port placed on the upper side of the instrument (chapter
“ NSTALLAT ON”) to the PC USB port through a standard USB cable.
.4 TURNING ON / OFF THE INSTRUMENT
TO TURN ON the instrument press the C key until the indicator turns on; then release.
The display shows:
XX.YY is the installed software version.
The instrument turns on all the display segments and symbols
MAX XXX.XXX capacity of channel 1
(or MAStEr if the“MAStr” functioning mode has been selected, or riPE if the “rEPE” functioning mode has been selected)
bt XXX in which XXX is a number from 0 to 100 which indicates the percentage of battery level (if present).
The indicator has an “auto zero at start-up” function: in other words it means that if at start-up a weight within +/- 10% of the
capacity is detected, it will be zeroed; if the weight is not within this tolerance, with a non approved instrument the display
shows the present weight after a few instants, while with an approved instrument “ZEro” is shown continuously on the
display, until the weight does not re-enter within this tolerance; the auto zero function at start-up may be disabled in the set-
up environment (only with non approved instrument); see SEtuP >> ConFiG >> PArAM >> Auto-0 parameter
(TECH.MAN.REF.).
By pressing the ZERO key for an instant while the version is shown in the LED display, the indicator will show the following
in this order:
MAStEr if the “MAStr” functioning mode has been selected or riPE if the “rEPE” functioning mode has been selected.
CLoCk if date and time is detected .
XX.YY in which XX indicates the instrument type, YY indicates the metrological software version.
XX.YY.ZZ is the installed software version.
XXXXXX is the name of the installed software.
bt XXX in which XXX is a number from 0 to 100 which indicates the battery level (if present).
-K- X.YY in which K identifies the type of keyboard: K=0 5-key keyboard, K=1 17-key keyboard.
X.YY is the installed software version.
After this, it shows the programmed capacity and the minimum division, “hi rES” (in case of NOT approved instrument) or
“LEGAL” (in case of approved instrument), the g gravity value, and finally it executes a countdown (self-check).
TO RESTART the instrument keep the C key pressed for 8 seconds long: the indicator will turn off, then release the key
and the indicator will automatically turn on.
TO TURN OFF the instrument keep the C key pressed until the “- OFF–“ message appears on the display; then release the
key.

6. FRONT PANEL KEYS AND INDICATORS ( key version)
The front panel of the indicator is designed for quick and simple weighing applications. t consists of a display with 6 digits,
25 mm in height, 7 LED indicators (depending on the model), and a 5-key water-proof film keyboard.
f the indicator has an LCD display, while weighing, various multifunction symbols indicating the functioning status will turn
on (see section “SYMBOLS ON THE LCD D SPLAY”).
