I assume this would work too; ( I also have got an A100R )

// --- Vector A100LK ---
#if (WSpeedSensor_Type == 70)   // Vector Intruments, model A100LK : Speed Pulse/sec 0.514444 m/s
#define ClickPerRev  10
#define FORM_FACTOR  0.5144
#endif

// --- Vector A100L2 ---
#if (WSpeedSensor_Type == 71)   // Vector Intruments, model A100L2 : Speed Pulse/sec 0.514444 m/s
#define ClickPerRev  13
#define FORM_FACTOR  0.5144
#endif

// --- Vector A100R ---
#if (WSpeedSensor_Type == 72)   // Vector Intruments, model A100R : Speed Pulse/sec 0.514444 m/s
#define ClickPerRev  1
#define FORM_FACTOR  0.5144
#endif
