6. The keyboard test will place two dots on the display for each key on the display, including
the numeric keypad. Pressing a key will cause the upper of the two dots associated with the
key to go out. Test all of the keys in this manner. Tug on the safety key lanyard, to ensure
that the STOP key is operating normally.
7. Press and hold the STOP key or ENTER key to proceed to the heart rate test.
8. The heart rate test will display the heart rate being received during this test from either a
chest strap transmitter, the hand held system or a test transmitter.
9. Three heart rate values will be displayed. They are prefixed “U” for unfiltered, “F” for filtered
and “P” for Polar filtering. The Polar filtered heart rate will also appear in the normal heart
rate display, since Polar filtering is the filtering used during normal operation. The right most
red LED in the smart rate display will flash each time a heart beat is detected.
10. Press the STOP or ENTER key to proceed to the lift test.
11. Two numbers will be displayed, the percent of lift and A/D number related to the current lift
position. The A/D (analog to digital) number represents the lift potentiometer reading. The
A/D number will be in the range of 0 to 255.
12. The lift may be operated using the INCLINE keys. The incline percentage and A/D numbers
will change accordingly. Care must be taken while operating the lift in this mode because
the normal upper and lower range limits are not in effect. It is possible to operate the lift to
it’s physical limits and may cause the lift motor to jam.
13. The A/D reading will be used later in this service manual to calibrate the lift.
14. Press and hold the STOP or press the ENTER key to proceed to the belt speed test.
15. The speed of the running belt is controlled by the SPEED keys during this test.
16. The following values are displayed; time (that the running belt has operated during this test),
current (in amps through the drive motor), belt speed (in MPH) and power bits (PWM value).
17. This test is valuable in diagnosing treadmill load conditions such as running bed and/or
running belt condition. As load is increased, the speed is kept at a constant value (as set via
the SPEED keys) and the current and power bits will vary proportionately to the load.
18. It is suggested that you perform this test on a treadmill known to be in excellent operating
condition. Note the values displayed at a fixed speed (such as 3 MPH) and your body
weight. Those values may then be used to benchmark the operation of treadmills you are
diagnosing.
19. Press and hold the STOP or press the ENTER key to proceed to the belt power test.
20. The belt power test is similar to the belt speed test except that the SPEED keys control the
power bits (PWM value) instead of the belt speed.
21. The same (see step 16) values will be displayed as in the belt speed test.
