SCALE FACTORS28The Model 5886-1400 Control includes the abilityto scale incoming counts. This means that for eachpulse received on the count inputs, a fraction ormultiple of that pulse is counted. Scaling can beused to compensate for wear on measuringwheels, consistent material slippage or materialstretch, to make conversions between differentunits of measure (inches to centimeters, for exam-ple) or to totalize parts produced from multiple partmanufacturing processes (such as 6 parts pro-duced for each operation of a press).Figure 22. Table of Scale Factors versus Count SpeedThe scale factor can be a number from 0.0001 to9.9999. This number becomes a factor by whichincoming count pulses are multiplied. The sum ofthe scaled count pulses is shown on the frontpanel display.ENTERING A SCALE FACTORFunction 5 selects the Scale Factor. Note that anyjumper connected to the Program Inhibit terminalon the rear panel of the counter must first be dis-connected before the Scale Factor may be modi-fied. To change the Scale Factor, follow thesesteps:1. Press the “FUNCTION” key. The displayblanks to indicate that the key has beenpressed.2. Press the “5” key. The display indicates thisdigit.3. Press the “ENTER” key. The current value forthe Scale Factor is displayed. If the value doesnot need to be changed, proceed on to step 6below.4. Press the digit keys for the desired entry.
