This explanation concerns the speedometer equipped with 2 buttons (named: FCN and ON / CLR), one of the signs that the speedometer is equipped with 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.

The speedometer is a must-have add-on for your NSD Spinner powerball if you are competitive and want to outdo your family or friends. In addition, it is an excellent way to gain insight into your progress for rehabilitation and sports-related training programs.

Features of the NSD Spinner powerball speedometer with 2 buttons

Function 1: Total number of revolutions
The function "Total Revolutions" shows the number of revolutions in multiples of hundreds. For example, if the counter shows 45 as opposite, this effectively means a number of revolutions of 4500 that have been counted so far. Press the "FCN" key repeatedly until the above symbol is displayed, if necessary press and hold the "ON / CLR" key to delete the stored value. When the number of revolutions exceeds 18,000, 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, it means that the rotor turns a number of revolutions of 12345 per minute around its own axis. Press the "FCN" key repeatedly until the above symbol is displayed. This function does not remember historical scores.

Function 3: Top speed
The "Top speed" function 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" key repeatedly until the above symbol is displayed, then press the "ON / CLR" key to clear the stored value for the current session, press it again to also delete the historically stored value.

If the symbol flashes, it means that a new record has been detected.

Functions 4, 5 & 6: Force index
The "Force index" function 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" key repeatedly until the above symbol is displayed. The measurement starts when the symbol starts to flash. Press "ON / CLR" to delete the stored readings.

Tips for using the NSD Spinner powerball speedometer with 2 buttons

The batteries of the digital speedometer can be replaced, detach the counter from the powerball and loosen the 2 small screws at the bottom. Replace the button cell batteries with new ones (type: Lr626), and reattach the screws in their original position.
There are a number of models of this speedometer in circulation. The functionality is identical and the difference is purely cosmetic. There is a black model and a gray model.
This speedometer is not suitable for the so-called high speed powerballs, such as the PB-588H (450hz). This powerball model has its own type of speedometer that can handle the higher speeds better.
If you accidentally press the buttons with the inside of your hand when using the powerball, you can also hold the powerball the other way around in your hand, so that the rotor opening is on the inside of your hand. Always watch out for the rotating rotor, because at full speed it can cause painful blisters.
