Allmänt
a. Vågen är utrustad med nivå libell under vågplåten samt fyra justerbara fötter. Var noga med att justera
”bubblan” till centrum av den inre ringen.
c. Vågen bör alltid användas i en miljö som är så fri som möjligt från temperaturvariationer, damm,
vibrationer, drag, fukt eller i korrosiv miljö. Dessa faktorer påverkar hållbarhet och tillförlitlighet.
d. För kontinuerlig drift anslut vågen till nätet med nätadaptern. Vi rekommenderar att inte maskiner, tex
borrmaskiner, används på samma säkring. Vi rekommenderar att vågen ansluts till ett vägguttag som
står inkopplat hela dygnet. Undvik att ansluta vågen till nät som är strömlöst över natten, om så är
nödvändigt rekommenderar vi att autopower off funktionen aktiveras.
e. För högsta noggrannhet bör vågen stå på 15 minuter innan den används.
f. En mekanisk transportsäkring till lastcellen är placerad på undersidan av vågen (markerad med etikett).
Lossa skruvarna och förvara dom för eventuell framtida transport av vågen.
g. Finns tveksamhet om hur vågen ska monteras eller om komplett information önskas finns utförlig
information i den kompletta instruktionen. Den kan laddas hem på www.vetek.se.

Tryckknappar
ON/OFF Till / Från
ZERO Nollställning av vågen när vågplattan är obelastad (lasten måste vara <+-2% av max
kapaciteten). Viktdisplayen visar ZERO längst ned till vänster när den är stabil.
TARE Lagrar taravikten i minnet när man lägger på ett emballage eller t.ex. en skål. Vågen visar
sedan nettovikten. Viktdisplayen visar NET/TARE längst ned till vänster.
MODE Val av enhet kg, g, lb, lb-oz, pcs, %.
PRINT Ger printkommando till skrivare. OBS Vågen måste ha option RS232 utgång.
Strömförsörjning
•I normal läge ansluts vågen till 230 VAC.
•Blybatteriet räcker för ca 120 timmars drift och det tar ca 8 timmar att ladda det. När laddning
pågår lyser dioden i fönstret CHARGE röd, när batteriet är fullt lyser dioden grön.
•En symbol visas när batteriet har låg kapacitet.
”Vanlig vägning”
Nollställning & Tara.
1. Närhelst det visas ett värde i fönstret med vågskålen obelastad, går det att nollställa vågen genom att
trycka på ZERO.
2. Lagring av Tara i minnet. Placera en tom behållare på vågskålen, tryck på TARE, ordet Tare skall då bli
synligt i det nedre vänstra fönstret (intill lysdioden) vikten på behållaren är nu lagrad i vågens minne.
3. Lägg önskat material i behållaren, vågen visar nu nettovikten.
4. Om ni nu tar bort behållaren med innehåll, visas behållarens vikt så som negativt värde. Tryck TARE
för att återställa vågen.
Att räkna småsaker
Detta är en våg för ”vanlig vägning” men den har även en enkel räknefunktion.
Räkna enheter
Vågen är utrustad med genomsnitt beräkning, Denna funktion kompenserar för mindre viktskillnader i
provvikterna. Provvikterna bör väga minst 0,8 x vågensgradering. Är vikterna för små för att räknas med
bra noggrannhet piper vågen.
1. Tryck på MODE tills displayen visar 0 PCS
2. Tryck på TARE en gång, displayen visar CAL.
3. Lägg på 25, 50 eller 100 provvikter på vågen, ju fler ju noggrannare blir räkningen. Tryck på TARE tills
displayen visar det valda antalet.Vänta en liten stund tills displayen visar antalet
4. Vågen visar nu antalet enheter på vågplattan.
% Vägning
1. Tryck på MODE tills displayen visar 0 %
2. Tryck på TARE en gång, displayen visar CAL.
3. Lägg på den provvikt som ska motsvara 25, 50 eller 100%. Tryck på TARE tills displayen visar det
valda %-värdet. Vänta en liten stund tills displayen visar detta värde.
4. Vågen visar nu i %.
Ett tips:
Det går inte att tarera bort en tom ask eller låda innan dessa funktioner aktiveras. Men man kan ställa på
denna ”dödvikt” om det inte väger för mycket innan man startar vågen.
