9. ng channel measures the revolutions according to the L i r parameter and when L i r 60 it simply measures the frequency on the input Ix Hz This mode allows great precision of measuring when noise is low and no filtering is needed d 0 d L S 0 4 Generator mode t YP GEn When used in generator mode CN6S outputs frequency in the band 0 01Hz 5 5kHz The user must choose proper frequency less than 10 Hz ifthe Counter has the standard relay output for this channel This mode is to be used only for units that are equipped with transistor output for service purposes There are two parameters Sh F and dP that facilitate the display of PV in CN6S In rpm frequency meter PV indicates the measured value shifted by S h F digits to the left so some of the fractional digits can be seen When in length speedo meter PV is shifted to the right to hide unnecessary digits fractions of the meter In this case the user can select a proper value for the dP parameter and set the decimal point on the desired place For instance for a speedometer with S h F 0 the user can select d P 4th to visualize the velocity in m min with three digits after the decimal point If the parameters are set Sh F 2 and dP 2nd the velocity will be in m min with only one digit after the decimal point s Chapter IV VI Use of the formula channel ch3 In CN6S is available the so called formula channel ch3 which can be activated only if chl and ch2 are in
