Introduction



ThankyouforselectingtheExtechInstrumentsModelSC600ElectronicCountingScale/Balance.



The SC600 is microprocessor controlled and uses a load cell transducer for high accuracy and

optimumperformance.TheSC600offersalargemeasurementcapacity,highresolution,andlarge

easy to read display. The slide switch on the back of the scale allows for the selection of

measurementunits(gramorounce).



A self‐calibration utility is built‐in and the calibration data is stored internally even upon power

down. The RS‐232 PC interface allows for the transfer of measurement data between the SC600

andaPC.



The SC600 includes ‘bubble’ level, adjustable rubber feetfor leveling, and heavyduty ABSplastic

housing.AnACadaptormaybeusedtopowertheunitortheunitmaybeusedonbatterypower.

Foracollectionofobjectsorpieces(eachpiecehavingthesameweightasthenext),theSC600

can calculate the number of these objects in a collection. A group of pieces can be used as a

sampleexampleingroupsof10,20,50,or100pieces.

1. Prepare a

 group of pieces (ina groupsize of10, 20, 50,or 100pieces). This will be the

‘standard’ that the SC600 uses to count subsequent collections of pieces. Do not place
