1. EPS SERIES ELECTRONIC BALANCE USER S MANUAL 1 Description EPS series portable electronic scales are precision weighing instruments The portable advanced scale consists of a housing constructed of a material which is impact resistant a one piece solid state precision electronic PC board with a 5 digit LCD displayer which is 0 5 inches in height and a strain gauge load cell inside All portable balances are initially factory set to measure in grams and can be set to other units of measure as desired Each balance operates through a series of menus that enable precise calibration and the selection of various parameters that enhances operation A built in lock switch prevents calibration settings from being changed Power is supplied through an AC adapter or batteries 2 Setup menus Press and hold the MODE key for 3 seconds to access the setup menu continue to press the UNIT key to make selection among Unit unit selection A OFF automatic power off CAL calibration and END exit menu In this process you can press TARE key to access a submenu and exit the menu by another touch on TARE when END appears 2 1 Unit selection The unit selection submenu permits you to specify which weighing units and operating modes will be enabled for use during operation The adjacent table lists the units and modes available on the EPS series balances Proceed as Display Weighing unts Follow2. and wait for a few seconds until the displayer stops flashing and shows the value of the calibrating mass that indicates calibration finishes and normal weighing can be done 2 3 2 Linearity calibration When the scale displays LINE press TARE key to see the scale flashes Wait for a few seconds the scale flashes half of the value of the full load specified Put onto the pan the calibrated mass corresponding to the value displayed The scale then flashes the value of the required calibrated mass for full load a few seconds later Put on the corresponding weight to wait till the scale stops flashing and displays the value of the calibrated mass loaded thus the calibration finishes normal weighing can be done Remark Scales are factory calibrated When linearity calibration is necessary or a load cell is replaced please use an accurately calibrated mass to calibrate the scale 3 Backlight Press MODE key to switch on or off the backlight 4 RS232C communication 4 1 Wiring method Connect the scale with PC as below 1 Empty 1 2 RXD j lt 2 RXD 3 TXD 3 TXD 4 4 p 5 G __ 5 G 6 6 7 7 s 8 9 Empty 9 4 2 Baud rate 9600 4 3 Data format output 6 XXX XX Unit lt CR gt lt LF gt All segments above belong to ASC II in which the unit can be that set for the scale 4 4 Demonstrating software of communication a The super end under Win9x NT 2000 XP b The debugging ass
