Instruction: NSD speedometer single button
An NSD Spinner training really becomes fun with the help of a digital speedometer. The 6 functions of this speedometer are explained in more detail in this manual. This instruction concerns the speedometer that is equipped with only 1 button (named: FCN / CLR). This is one of the signs that the speedometer is equipped without batteries.
When the powerball is equipped with a digital speedometer, accurate trainingprograms can be followed using various statistics that are measured: the number of revolutions in multiples of 100, the current speed in rotations per minute, the top speed in rotations per minute, and a force index value that measures the number of revolutions per 3 time units: 30, 60 and 90 seconds.
This version of the speedometer works without batteries and switches itself on when a speed of approx. 2000 rotations per minute is reached, and switches off automatically when the rotor stops rotating.
Characteristics of the NSD Spinner Speedometer with 1 button
- Digital LCD display, starts operating at a speed of approximately 2000 rotations per minute. At this speed, a red-tinted background lighting also lights up, which is useful for usage in a dark environment. The faster you spin, the brighter the lighting will shine.
- Function / Clear button. Switches between the different functions of the speedometer, or press and hold it inside a function to clear the memorized value of the selected function.
The speedometer is attached to the NSD Spinner instead of the cover. The cover must be removed to make room for the speedometer. Remove the cover by getting under the edge with your nails, you can also use a thin screwdriver or knife to get under the edge. Watch out for your fingers! Then place the speedometer with its two protrusions over the two recesses in the powerball shell and push it with your thumbs until it clicks into place.
Features of the NSD Spinner powerball speedometer with 1 button
Function 1: Total number of revolutions
The function "Total number of revolutions" shows the number of revolutions in multiples of hundreds. For example, if the counter shows 45, it effectively means a number of revolutions of 4500 that have been counted so far. Press the "FCN / CLR" button repeatedly until the corresponding symbol is displayed. Press and hold the "FCN / CLR" button to clear the stored value of this function. When the number of revolutions exceeds 27,000, the counter will stop counting.
Function 2: Current speed
The "Speedometer" function shows the current number of revolutions in revolutions per minute. For example, if 12345 is shown, this effectively means that the rotor is rotating a number of revolutions of 12345 per minute around its own axis. Press the "FCN / CLR" button repeatedly until the corresponding symbol is displayed. This function does not remember historical scores.
Function 3: Top speed
The function "Top speed" shows the highest measured speed that the counter has ever measured. For example, if 12345 is shown, this effectively means that the highest measured speed was a number of revolutions of 12345 per minute. Press the "FCN / CLR" button repeatedly until the corresponding symbol is displayed, then press and hold the "FCN / CLR" button to delete the stored value.
The highest score is stored for a period of approx. 48 hours, after which the counter 'forgets' this score, unless the powerball is used in the meantime and the counter powered again.
Functions 4, 5 & 6: Force index
The function "Force index" shows the number of revolutions that take place in 3 different time intervals: 30, 60 or 90 seconds. For example, if the LCD shows the value 30, the counter will keep track of the number of rotations per minute for 30 seconds. At the end of the 30 seconds, the counter will show the total number of revolutions measured in this time interval.
Press the "FCN / CLR" key repeatedly until the above symbol is displayed in combination with the time unit to be used. The measurement starts when the symbol starts to flash. Press "FCN / CLR" to delete the stored scores.
