Daytronic CorporationBALANCE Controls: The coarse (Rc) and fine (Rf ) BALANCE controls areused to set the module output to zero when the transducer is unloaded.SPAN Controls: The coarse (c) and fine (f) SPAN controls are used to setthe output to the Equivalent Input value when the CAL button is pressed.CAL Pushbutton: The CAL pushbutton provides for enabling or enteringthe calibration mode. The Cal resistor is shunted across the + Signal and+ Sense terminals when the button is pressed, supplying an EquivalentInput value to the module.Figure 5. Front-Panel Descriptionac power. Allow 5 minutes of warm-up for stabilization of transducercharacteristics.(b) With the transducer unloaded, set the module output to zero using thecoarse (R c ) and fine (Rf) BALANCE controls. In some instances, anintegral digital indicator will be used to display the conditioner output(Model 3270 or 3370). When only the conditioner is supplied (3170), anexternal indicator must be used to monitor the conditioner output.(c) Load the transducer to a convenient up-scale value which is greater thanone half of full scale. Adjust the coarse (c) and fine (f) SPAN controlsuntil the output signal causes a reading equal to the dead weight value.Remove the dead weight, then press the CAL button and note theindicator reading obtained. This reading can now be used in futurecalibrations since it is related to a value obtained thru dead weight11 |
