Using the computer
49
After setting the programmed power, you can enter it by pres-
sing the MODE key (fig. 23). Once the programmed power has
been entered, the SLOPE value disappears as long as you are
cycling in the WATT prg mode. The computer keeps track of the
most recently programmed power, even after it has been turned
off. To exit from the programmed power, you should press the
SET key twice, which will put you back in the SLOPE mode.
Power (Watt) equals Effort times Speed
During cycling, the Basic will use SLOPE to adjust the power
(watts) you programmed. Suppose, for example, you have
programmed a power of 400 watts and you want to pedal this
relatively high power, using relatively little effort (e.g. resistance
39 x 26) and a relatively low speed (e.g. a pedalling frequency of
70). The SLOPE cannot provide sufficient resistance to attain the
programmed power. You will see that the WATT designation at
the bottom right (actual power) does not agree with the
programmed power (WATT prg).
WATT prg will start to flash at the upper left of the display
(fig. 24) to indicate that you are outside the computer's field of
operation. By adjusting your resistance (greater/heavier) and
pedalling frequency (higher), you will soon find yourself returning
to the computer's field of operation. WATT prg will then light up
continuously.
Conversely, if you have programmed relatively low power and
you attempt to attain it with relatively great effort (e.g. resistance
52 x 16) and a high speed (e.g. pedalling frequency of 100), the
actual power will logically extend beyond the programmed
power. Here, too, you will be outside the computer's field of
operation, with WATT prg flashing in the upper left corner.
Adjust acceleration and pedalling frequency until you reenter the
computer's field of operation.
