Use the following string format:SddddddTdddd.R(cr)(lf)orSddddddTdddd.L(cr)(lf)Where…S = Speed in rpm. (No leading zeroes are used.)d = Decimal digit 0 through 9.T = Torque in units selected during setup. (The torque value always contains a decimal point.)L = Counterclockwise dynamometer shaft rotation (left).R = Clockwise dynamometer shaft rotation (right).. = Decimal point. (The decimal point location depends on the specific dynamometer andtorque range in use.)Note: When an “A” is in the R/L position (e.g. SdddddTdddd.A(cr)(lf)),it is an indication that the unit is in an alarm condition.Note: The (cr) and (lf) characters will not display.
