5.3 DFWPM POWER SUPPLY
The instrument can be powered with 4 AA rechargeable or not rechargeable batteries which are in the extractable battery
box.
It 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 “INSTALLATION”), 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

5.4 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
