Application
The instrument provides isolated aux. power.(regularly 5V/80mA) which allows1-4 loadcells connection directly. Up to 6 controll outputs are available for group ingredients weighing or fast/slow weighing;Data/Peak value holding function for choice.RS485 communication interface provides remote link with PC/PLC.Besides,you can Start/Pause/Accumulate/Clear tare weight/average/ clear zero,etc. for the displaying weight with external control terminal.

Set USP=Standard weight(suggest more than 20% load cell scale) set PVF= 0000. c.Without any weight on the instument,press DOWN key >5s until OK flashes. Thats to set the zero point and it displays 0.0; d. Add the weight equal to setted USP,press UP key>5s until OK flashes. Thats to set the high value.and it displays the added weight. e. Should big error happens,just repeat the above operation. f. After finish the above operation, press<</Rst key >2 s. to clear tare weight. g.

On displaying estate,press UP and DOWN key for more than 3 seconds to access to parameter SEL setting.The operation steps are the same as the other settings. After setting, press UP and DOWN key to quit. This operation is to modify SEL value ONLY..Other parameters are fixed by manufactor.Please do not make any changement.
If SEL=XXX1XX,
that means the user cant do on-site weight adjustment by pressing UP/DOWN key. If SEL=XXX0XX, that means the user can do on-site weight adjustment by pressing UP/DOWN key. Note: *** X means the original data. Do not make modification. ***Just make modification to data 1/0 ***Factory setting is XXX0XX. After on-site adjustment,make sure SEL=XXX1XX.This is to avoide incorrect display by users inapropriate key-pressing operation.
SET Zero point adjustment for current/volt output,4mA/ 0.1V adjustable. Available when have analog output.Factory setting,do not make modification. Full point adjustment for current/volt output,20mA/ 10V adjustable. Available when have analog output.Factory setting,do not make modification. A/D convert data when no weight on the loadcell,that is the factory setting for zero point.
Adjustment for large-tonnage scale loadcell:
A. Set USP=the total weight of all input loadcells(eg. each loacell is 1000KG, 3 loadcells in total, the total weight is 3000kg.Then set USP=3000.). Set PVF=0.000, B. Record the displaying value(PV1) when no weight on the loadcells(eg.100.5kg). C. Add the standard weight(the weight should be larger than 20% of the total loadcell weight,eg.500kg). Recorder the displaying value(PV2)(eg. 630kg). D. Calculation: The actual weight added(eg. 500kg)/(PV2-PV1) eg.500/(630-100.5)=0.9442. E. Calculation: USP*(The actual weight added/(PV2-PV1)). eg. USP*(500/529.5)=2832.86, Then set USP=2832.86 again. F. The adjsutment is finished.
